Description

Technical Field

[0001] This application relates to the field of coking coal process technology, and in particular to a method and apparatus for determining the comprehensive activity index of coking coal. Background Technology

[0002] According to classical coal petrographic theory, different microscopic components in coking coal exhibit varying activities during the coking process. Generally, vitrinite and chalcanthite are considered active components, while inertinite and minerals are considered inert components. However, studies have shown that some inert components are not entirely inert during carbonization. For example, inertinite in some Australian coking coals can exhibit caking properties during coking, and 50% of the inertinite in Canadian coking coal should be classified as active components. However, during coking, apart from minerals remaining inert, vitrinite, chalcanthite, and inertinite in coal all exhibit varying degrees of activity, and the activity of each component changes with the degree of metamorphism. Therefore, accurately determining the activity of each microscopic component in coking coal has become one of the key research directions in this field. Summary of the Invention

[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0041] This application proposes a method and apparatus for determining the comprehensive activity index of coking coal. Specifically, the method and apparatus for determining the comprehensive activity index of coking coal according to embodiments of this application are described below with reference to the accompanying drawings.

[0042] Figure 1 This is a flowchart illustrating a method for determining the comprehensive activity index of coking coal, provided in an embodiment of this application. Figure 1 As shown, the method for determining the comprehensive activity index of coking coal includes the following steps:

[0043] Step 101: Obtain the average maximum reflectance of the vitrinite and the distribution map of the maximum reflectance of the vitrinite.

[0044] As an example, the maximum reflectance of vitrinite can be measured on coking coal, with at least 100 test points. The mean μ of the test data (measured maximum reflectance of vitrinite) is calculated, and this mean μ is taken as the average maximum reflectance of vitrinite. Based on the test data, the percentage content of each measurement point at each level (or half level) was statistically analyzed in units of 0.10% reflectance interval (level) or 0.05% reflectance interval (half level), and the maximum reflectance distribution map of vitrinite was plotted.

[0045] Step 102: Obtain the contents of vitrinite, inertinite, and chitinite.

[0046] Step 103: Determine the standard deviation of vitrinite reflectance test based on the maximum reflectance distribution map of vitrinite.

[0047] Optionally, in some embodiments of this application, the maximum reflectance distribution map of vitrinite can be corrected using a normal distribution function to obtain a correction curve. The standard deviation of the correction curve is then calculated and determined as the standard deviation of the vitrinite reflectance test. The formula for the correction curve is shown below.

[0048]

[0049] Where x is the maximum reflectance of the vitrinite, f(x) is the distribution ratio corresponding to the maximum reflectance x of the vitrinite, μ is the mean, and σ is the standard deviation of the vitrinite reflectance test.

[0050] As an example, Table 1 shows the statistical characteristics of the maximum reflectance distribution of vitrinite in a certain type of coking coal provided in the embodiments of this application. Based on the measured values ​​of the maximum reflectance of vitrinite, the following can be obtained: Figure 2 The diagram shows the maximum reflectance distribution of vitrinite in coking coal. Correcting the vitrinite distribution yields a correction curve (e.g., ...). Figure 2 The standard deviation of the vitrinite reflectance test can be further determined based on the calibration curve (as shown in the curve).

[0051] Table 1

[0052]

[0053] Step 104: Determine the relative activity of the vitrinite group, the relative activity of the inertinite group, and the relative activity of the chitinite group based on the average maximum reflectance of the vitrinite and the standard deviation of the vitrinite reflectance test.

[0054] It should be noted that during the coalification process, the physical and chemical properties of each microscopic component in coal are constantly changing. The relative activity of each microscopic component in coking coal is affected by the degree of metamorphism. Due to differences in the degree of metamorphism, the activity of the same microscopic component may differ in different coals. Therefore, in this embodiment, the degree of metamorphism of coking coal is characterized by the average maximum reflectance of vitrinite, and the relative activity of each microscopic component is determined based on the average maximum reflectance of vitrinite and the standard deviation of vitrinite reflectance test.

[0055] In one possible implementation, since the relative activity of vitrinite is a function of the degree of deterioration, and in this embodiment, the degree of deterioration is represented by the average maximum reflectance of vitrinite, the characteristic of a normal distribution of vitrinite reflectance can be simulated. Based on the average maximum reflectance of vitrinite, the vitrinite reflectance corresponding to the maximum relative activity of the vitrinite group, and the standard deviation of the vitrinite reflectance test, the relative activity of the vitrinite group is fitted with a normal distribution function to determine the relative activity of the vitrinite group. Similarly, the relative activity of the chitinous group and the inertinous group are respectively related to the degree of deterioration; therefore, the relative activity of the chitinous group and the inertinous group can be determined based on the average maximum reflectance of vitrinite.

[0056] Step 105: Determine the comprehensive activity index of coking coal based on the content of vitrinite, inertinite, chalcanthite, relative activity of vitrinite, relative activity of inertinite, and relative activity of chalcanthite.

[0057] Optionally, in some embodiments of this application, the comprehensive activity index of coking coal can be determined by the following formula:

[0058] CRICM = V × R V +×R I +×R E

[0059] Wherein, CEICM is the comprehensive activity index of coking coal, represents the vitrinite content, I represents the inertinite content, E represents the chrysinite content, and R represents the vitrinite content. V R represents the relative activity of the vitrinite. I R represents the relative activity of the inert group. E The relative activity of the chitinous group.

[0060] Optionally, in some embodiments of this application, when the coking coal is a blended coal (the blended coal includes multiple types of coking coal), the method for determining the comprehensive activity index of coking coal proposed in the embodiments of this application may further include: determining the proportion of each type of coking coal and the comprehensive activity index of each type of coking coal; and determining the comprehensive activity index of the blended coal based on the proportion of each type of coking coal and the comprehensive activity index of each type of coking coal. The determination of the comprehensive activity index of the blended coal can refer to the following formula:

[0061]

[0062] Wherein, TCRICM is the comprehensive activity index of the blended coal, i is the proportion of the i-th type of coking coal, and CRICM i denoted as the comprehensive activity index of the i-th type of coking coal.

[0063] As an example, Table 2 is a coal blending scheme table proposed in the embodiments of this application. In each scheme, the comprehensive activity index of the blended coal can be determined according to the blending ratio of each coking coal and the comprehensive activity index of each coking coal. Figure 3 This is a schematic diagram illustrating the relationship between the comprehensive activity index of blended coal and the post-reaction strength (CSR) of coke, as proposed in the embodiments of this application. Figure 3 As shown, the comprehensive activity index of blended coal can be used to evaluate the quality of coking coal, improve the scientificity and accuracy of coking coal quality evaluation, and provide guidance for the quality control of blended coal in the coking process.

[0065]

[0066] The method for determining the comprehensive activity index of coking coal according to the embodiments of this application utilizes the average maximum reflectance of vitrinite to reflect the degree of metamorphism of coking coal. By determining the activity of different micro-components in coking coal through the average maximum reflectance of vitrinite, the influence of differences in metamorphism on the activity of each micro-component can be overcome to a certain extent, thus improving the accuracy of the comprehensive activity index of coking coal. Furthermore, the method proposed in this application is simple to operate and easy to implement, which can reduce the raw material procurement costs for coking enterprises.

[0067] Figure 4 This is a flowchart illustrating another method for determining the comprehensive activity index of coking coal provided in an embodiment of this application. Figure 4 As shown, the method for determining the comprehensive activity index of coking coal includes the following steps:

[0068] Step 401: Obtain the average maximum reflectance of the vitrinite and the distribution map of the maximum reflectance of the vitrinite.

[0069] Step 402: Obtain the content of vitrinite, inertinite, and chitinite.

[0070] Step 403: Determine the standard deviation of vitrinite reflectance test based on the maximum reflectance distribution map of vitrinite.

[0071] Step 404: Determine the first vitrinite reflectance and the preset comparison threshold. The first vitrinite reflectance is the vitrinite reflectance corresponding to the maximum relative activity of the vitrinite group.

[0072] It should be noted that the relative activity of the vitrinite is a function of the degree of deterioration, and in the embodiments of this application, the average maximum reflectance of the vitrinite is used. Indicates the degree of spoilage. Figure 5 This is a schematic diagram of the relative activity curve of vitrinite provided in the embodiments of this application. According to the classical coal petrography theory, such as Figure 5 As shown, the vitrinite group exhibits optimal caking properties in medium-rank coking coal. The relative activity of the vitrinite group is set to 1.0, representing the maximum relative activity. The vitrinite reflectance at this point is the first vitrinite reflectance A (i.e., the vitrinite reflectance corresponding to the maximum relative activity of the vitrinite group). When the vitrinite reflectance is less than B (i.e., the lower limit of vitrinite reflectance corresponding to a relative activity of 0) or greater than C (i.e., the upper limit of vitrinite reflectance corresponding to a relative activity of 0), the relative activity of the vitrinite group is set to 0. Figure 5 It can be seen that when the vitrinite reflectance is less than A, the relative activity of the vitrinite group increases with increasing reflectance; when the vitrinite reflectance is greater than A, the relative activity of the vitrinite group decreases with increasing vitrinite reflectance. The specific values ​​of A, B, and C are determined based on the coal blending structure.

[0073] According to relevant experimental data, generally, A represents a value of vitrinite reflectance between 1.1% and 1.3%, B represents a value of vitrinite reflectance between 0.3% and 0.6%, and C represents a value of vitrinite reflectance between 1.8% and 2.1%. The distance between AB and AC is the same, i.e., CA = AB.

[0074] Step 405: Determine the relative activity of the vitrinite group based on the average maximum reflectance of the vitrinite, the reflectance of the first vitrinite, and the standard deviation of the vitrinite reflectance test.

[0075] Optionally, in some embodiments of this application, the relative activity of vitrinite can be fitted using a normal distribution function, wherein the relative activity of vitrinite can be determined by the following formula. This formula allows for the assignment of different activity weights to vitrinite samples with different degrees of deterioration.

[0076]

[0077] Among them, R V The relative activity of the vitrinite. Let be the average maximum reflectance of the vitrinite, A be the first vitrinite reflectance, σ be the standard deviation of the vitrinite reflectance test, and K be the proportionality coefficient.

[0078] Step 406: Determine the relative activity of the chitinous group based on the average maximum reflectance of the vitrinite and the preset comparison threshold.

[0079] It should be noted that the content of vitrinite in coking coal is not high. During carbonization, the vitrinite completely melts and can improve the melting characteristics of the surrounding vitrinite. Therefore, the vitrinite has high reactivity. Numerous studies have shown that when the reflectance of vitrinite exceeds a certain threshold, the properties of the vitrinite are the same as those of the vitrinite. Therefore, in some embodiments of this application, when the average maximum reflectance of vitrinite exceeds a certain threshold, the vitrinite exhibits the same properties as the vitrinite. When the relative activity of the chitinous group is less than a preset comparison threshold, it can be determined as the first activity value. When the average maximum reflectance of the vitrinite is... When the relative activity of the chitinous group is greater than or equal to a preset comparison threshold, the relative activity of the chitinous group is kept consistent with that of the vitrinous group. As an example, the preset comparison threshold can be set to 1.2%, and the first activity value can be set to 1.0. That is, when the average maximum reflectance of the vitrinous group is less than 1.2%, the relative activity of the chitinous group can be determined to be 1.0. When the average maximum reflectance of the vitrinous group is greater than or equal to 1.2%, the relative activity of the chitinous group is kept consistent with that of the vitrinous group.

[0080] Step 407: Determine the relative activity of the inert group based on the average maximum reflectance of the vitrinite.

[0081] Figure 6 The maximum reflectance distribution histogram of various microscopic components of coking coal provided in the embodiments of this application is shown below. Figure 6 As shown, the reflectance distribution of the inert group is not concentrated, exhibiting a tail-like pattern. The inert group in low-rank coking coal has relatively high activity, which gradually decreases with increasing rank. Therefore, the relative activity R of the inert group can be considered as... I It can be considered as a linear function of vitrinite reflectivity. As an example, the relative activity of the inert group can be determined by the following formula:

[0082]

[0083] Among them, R I The relative activity of the inert group, This represents the average maximum reflectance of the vitrinite.

[0084] Step 408: Determine the comprehensive activity index of coking coal based on the content of vitrinite, inertinite, chrysinite, relative activity of vitrinite, relative activity of inertinite, and relative activity of chrysinite.

[0085] In the embodiments of this application, steps 401-403 and 408 can be implemented in any of the embodiments of this application. This application does not make specific limitations on these steps and will not elaborate further.

[0086] The method for determining the comprehensive activity index of coking coal according to embodiments of this application utilizes the average maximum reflectance of vitrinite to reflect the degree of metamorphism of coking coal. Based on the relationship between the activity of different micro-components in coking coal and the degree of metamorphism, a scientific and quantitative method for determining the relative activity of different micro-components is established. Determining the activity of different micro-components in coking coal through the average maximum reflectance of vitrinite can, to a certain extent, overcome the influence of differences in the degree of metamorphism on the activity of each micro-component, further improving the scientificity and accuracy of coking coal quality evaluation. Furthermore, the method proposed in this application is simple to operate and easy to implement, which can reduce the raw material procurement costs for coking enterprises.
