[0056] Embodiment 1
[0057] In order to provide effective data support for the optimization of petroleum-based carbon materials performance, such as Figure 1As shown, in an embodiment of the present invention, a method for predicting the performance of a petroleum-based carbon material is provided, comprising the steps of:
[0058] S11, constructing a database of refinery data; setting the structural data of the carbon material in the refinery data as first preset data;
[0059] The inventive ideas of the present invention include: since the raw materials of petroleum-based carbon materials are widely sourced and the types and components are complex, most of the existing prediction methods adopt single-factor analysis methods; under this method, there is a defect that the analysis of refinery data is not comprehensive enough, so the deviation between the predicted results and the actual results is too large, and therefore it is impossible to provide effective data support for the optimization of the performance of petroleum-based carbon materials.
[0060] In order to solve the above problems, the present invention conducts multi-dimensional analysis on the raw material data of petroleum-based carbon materials, the process control data of carbon materials, the structural data of carbon materials and the performance data of carbon materials, and pre-processes the refinery data; determines the correlation between various data of the refinery data and the production target carbon materials, and establishes a high-accuracy prediction model.
[0061] In an embodiment of the present invention, the refinery data are classified, and the structural data of the carbon material in the refinery data are set as the first preset data; wherein the structural data of the carbon material may include specific surface area, pore volume, tap density, and the like.
[0062] S12, preprocessing the refinery data, including updating the first preset data;
[0063] Updating the first preset data includes: using the structure data as input to calculate the data value of the preset property of the carbon material according to the preset carbon material model; the carbon material model is established according to the structure data of the carbon material; the preset property of the carbon material is used as a new data item; the preset property includes one or more of electron density, energy band structure, density of states, lattice constant, interatomic distance and chemical bond length;
[0064] For the production of petroleum-based carbon materials, refinery data includes a large number of data items; if the original values of these data items are used as feature data for model training and verification during modeling, the generated prediction model has poor prediction accuracy.
[0065] The inventors have found through research that some data items in the refinery data, such as the structural data of carbon materials, can be supplemented or replaced by the values of new data items of carbon materials to improve the prediction accuracy of the prediction model.
[0066] Next, in the embodiment of the present invention, new data items of the carbon material are set, such as: the electron density, energy band structure, density of states, lattice constant, interatomic distance and chemical bond length of the carbon material;
[0067] After the above settings, the specific process of preprocessing the first preset data may include:
[0068] With the specific surface area, pore volume and tap density of carbon materials as input, first principle calculations are performed according to the carbon material model to obtain data values of preset properties of carbon materials such as electron density, energy band structure and density of states, lattice constant, atomic spacing and chemical bond length. The obtained values of the preset properties are then used as new data item values to replace the original structural data of carbon materials such as specific surface area, pore volume and tap density.
[0069] It should be noted that the carbon material model is established based on the structural data of the carbon material; wherein the categories of the carbon material model may include needle coke, diamond, petroleum coke electrode, carbon fiber, carbon nanotube and graphene, etc.
[0070] Since the value of the new data item of the carbon material in the first preset data has a clearer influence on the performance of the carbon material, the prediction accuracy of the prediction model can be effectively improved through the above preprocessing.
[0071] Furthermore, in order to better improve the accuracy of the prediction model, the preprocessing process in the embodiment of the present invention may also include: updating the second preset data, including: converting each item of data in the second preset data into binary data by re-encoding; the second preset data is the raw material source data and the process condition data for producing raw materials in the refinery data.
[0072] In the implementation of the present invention, the raw material source data and the process condition data for producing the raw materials (i.e., the second preset data) are re-encoded according to one-hot coding because the conditions are relatively fixed, and each data is converted into binary data.
[0073] Furthermore, in order to further improve the accuracy of the prediction model, in an embodiment of the present invention, the preprocessing process may also include: updating the third preset data, including: respectively calculating the difference between each data in the third preset data and the corresponding standard data, and updating each data in the third preset data with the difference; determining the standard data includes, based on the set carbon material performance, determining the standard data corresponding to each data in the third preset data; the third preset data is the raw material physical and chemical properties data and the process control data of the carbon material in the refinery data.
[0074] The physical and chemical property data of raw materials and the process control data of carbon materials. For the production process of petroleum-based carbon materials, the values of these data items can determine their respective optimal values according to the carbon material performance of the product carbon; for example, under a certain carbon material performance standard, the optimal value of each data in the corresponding physical and chemical property data of raw materials, as well as the optimal value of each data in the process control data.
[0075] Next, in the embodiment of the present invention, for the set carbon material performance, the optimal value corresponding to each data item in the third preset data is predetermined, and the optimal value of each data item is used as the standard data.
[0076] After the above settings, the specific process of preprocessing the third preset data may include:
[0077] For a certain data item, the difference between the data of the data item and the standard data is calculated according to the corresponding standard data, and the data of the corresponding data item is updated with the difference result, thereby replacing the original data; for example: the standard data for determining the thermal expansion coefficient in the physical and chemical properties of raw materials is A, and the original thermal expansion coefficient obtained from the refinery data is B, and the difference between B and A is used to update the original thermal expansion coefficient data.
[0078] Since the difference between the third preset data and the standard data has a clearer influence on the performance of the carbon material, the prediction accuracy of the prediction model can be further effectively improved through the above preprocessing.
[0079] Among them, the physical and chemical properties data of raw materials may specifically include fraction distribution, distillation range, density, viscosity, carbon-hydrogen ratio, elemental composition, volatile matter, porosity and thermal expansion coefficient; the process control data of carbon materials may specifically include temperature, pressure, residence time and processing volume corresponding to each process type.
[0080] Further, in an embodiment of the present invention, updating the third preset data may also include: normalizing the covariance of the third preset data, removing data with large correlation, and performing a first dimensionality reduction. In this embodiment, a correlation coefficient analysis is performed on each data in the newly obtained raw material physical and chemical property data and the process control data of the carbon material. The correlation coefficient analysis is the normalized covariance between each data, and the data with large correlation is removed to perform a preliminary dimensionality reduction.
[0081] Furthermore, in an embodiment of the present invention, the updated first preset data, the second preset data and the third preset data can be subjected to secondary dimensionality reduction to obtain new feature data for each item; in practical applications, the principal component analysis (PCA) method can be used to further reduce the dimensionality of the above three types of preset data to obtain new feature data for each item after reduction.
[0082] Furthermore, in an embodiment of the present invention, preprocessing may also include: updating fourth preset data, including: determining the levels corresponding to various performance data of the target carbon material according to preset level classification rules; the fourth preset data is the performance data of the carbon material.
[0083] Since whether the performance of the carbon material meets the standard is judged based on whether each indicator is within a set range, in order to reduce the difficulty of correspondence between the independent variable data and the dependent variable data in the prediction model and reduce the difficulty of modeling the prediction model, in the embodiment of the present invention, a method of characterizing the data of each indicator (i.e., each data) of the performance of the carbon material with a set grade score is also adopted, specifically:
[0084] For each performance data item of carbon materials, a corresponding grading interval is set. For example, the data item of needle coke can be divided into multiple grades. In this way, the corresponding level can be determined according to the specific values of the needle coke performance data. Similarly, other data items such as carbon fiber and negative electrode can be divided into multiple grades.
[0085] It should be noted that, in the embodiments of the present invention, the number of classifications of each performance data item of the carbon material can be determined by those skilled in the art according to needs and experience, and is not specifically limited here.
[0086] S13. Using various data of the refinery data as characteristic data, a prediction model is established for the purpose of predicting the performance of the target carbon material.
[0087] In the embodiment of the present invention, the prediction model may select a neural network model or an integrated learning model according to the actual application; the neural network model or the integrated learning model is established according to the preprocessed data.
[0088] The prediction model is trained by the constructed training set, and the score of the target carbon material performance is output; the accuracy of the prediction model is verified by the constructed test set; in the embodiment of the present invention, the data set is composed of the scores of the new feature data and the various performance data of the target carbon material; and the data set is reasonably divided into a training set and a test set.
[0089] The prediction model is machine-learned through the training set, and the prediction model outputs the scores of various properties of the target carbon materials produced by different raw materials in each process route. The accuracy of the prediction model is then continuously cross-validated through the test set to obtain a prediction model with high accuracy.
[0090] The following is a specific example to illustrate the accuracy of the prediction model. For example, the ethylene tar produced by a refinery in Nanjing was analyzed and tested by experimenters. The tar's fraction distribution, distillation range, density, viscosity, carbon-hydrogen ratio, elemental composition, volatile matter and other physical and chemical properties and information about the tar-producing device were submitted to the prediction platform including the prediction model. The prediction platform was able to query that this type of raw material can be used to produce needle coke, and the best route is to produce 8-point quality needle coke products by delayed coking. According to this process route, the actual result is high-quality needle coke material, which also verifies the accuracy of the prediction model.
[0091] In summary, an embodiment of the present invention provides a method for predicting the performance of petroleum-based carbon materials, which first constructs a database of refinery data; sets the structural data of carbon materials in the refinery data as first preset data; then preprocesses the refinery data, including updating the first preset data; including: using the structural data as input to calculate the data value of the preset attribute of the carbon material according to a preset carbon material model; establishing the carbon material model according to the structural data of the carbon material; using the preset attributes of the carbon material as new data items; the preset attributes include one or more of electron density, energy band structure, density of states, lattice constant, atomic spacing and chemical bond length; using each item of refinery data as feature data, establishing a prediction model for the purpose of predicting the performance of the target carbon material.
[0092] The embodiments of the present invention effectively improve the prediction accuracy of the prediction model for the performance of the target carbon material by generating data that cannot be directly collected, such as electron density, band structure, density of states, lattice constant, atomic spacing and chemical bond length.
[0093] Furthermore, in an embodiment of the present invention, a multi-dimensional analysis can be performed on the raw material data of petroleum-based carbon materials, the process control data and production condition data of carbon materials, the structural data of carbon materials and the performance data of carbon materials, and the refinery data can be preprocessed; the correlation between various data of the refinery data and the performance of the production target carbon materials can be determined, and a high-accuracy prediction model can be established, thereby providing effective data support for the optimization of the performance of petroleum-based carbon materials.
[0094] In addition, the embodiment of the present invention is mainly based on feature data identification and prediction of target carbon materials, and establishes a technology that can quickly identify feature data and extract raw materials of petroleum-based carbon materials, forming an intelligent decision-making method that integrates raw material property analysis, optimal route selection, target carbon material product performance prediction and economic cost accounting of petroleum-based carbon materials.
