Description

Technical Field

[0001] The present invention relates to the technical field of coal liquefaction, and particularly to a method for evaluating the direct coal liquefaction performance, a storage medium, and an electronic device. Background Art

[0002] The direct coal liquefaction reaction is a process in which an oil-coal slurry prepared by mixing coal, a solvent, and a catalyst generates oil, water, and gas under high temperature and high pressure. At present, the free radical reaction mechanism of direct coal hydrogenation liquefaction has been widely recognized by many scholars. The coal liquefaction process is a process in which weak bonds in the coal molecular structure are broken to initiate free radical reactions. The complex molecular structure of coal is broken at high temperature to form free radicals with a single atomic structure, and under the action of a catalyst and a hydrogen-donating solvent, active hydrogen combines with the free radicals to stabilize the free radicals by hydrogenation, generating low-molecular-weight gases, water, oil, asphaltene and other products, and at the same time, it can also remove some heteroatoms such as nitrogen, oxygen, and sulfur.

[0003] However, there are many factors affecting the direct coal liquefaction performance. It is of great significance to explore the influence of each influencing factor on the direct coal liquefaction performance. For example, some experimental parameters such as reaction conditions have certain commonalities in their influence on the direct coal liquefaction performance, but there are differences in the liquefaction reactivity of different coal types. Therefore, if we explore the influence of each factor on the direct coal liquefaction performance, it will consume a large amount of time cost, and if we consider the influence of more factors on the direct coal liquefaction performance, the time consumed will increase exponentially.

[0004] Therefore, how to provide an effective, accurate, and rapid method for evaluating the direct coal liquefaction performance of a reaction kettle has become an urgent problem to be solved. Summary of the Invention

[0042] It is easy to understand that according to the technical solution of the present invention, under the condition of not changing the essence of the present invention, those of ordinary skill in the art can use various structural ways and implementation ways that can be mutually replaced. Therefore, the following specific embodiments and the drawings are only illustrative descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the invention.

They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0044] This application is mainly applied to the direct liquefaction of coal in a reactor, such as Figure 1 As shown, a method for evaluating the direct liquefaction performance of coal provided by an embodiment of the present invention includes:

[0045] Step S101: Obtain real-time influence factor information that determines the direct liquefaction performance of coal. The real-time influence factor information includes coal factor information, catalyst factor information, hydrogen-donating solvent factor information, and reaction condition factor information;

[0046] Step S102: Input the real-time influence factor information into a preset target evaluation model to obtain liquefaction performance evaluation indicators. The liquefaction performance evaluation indicators include conversion rate, oil yield, water yield, gas yield, hydrogen consumption, and asphaltene yield;

[0047] Step S103: Determine the direct liquefaction performance of coal according to the liquefaction performance evaluation indicators.

[0048] Specifically, when the direct liquefaction of coal is carried out in a reactor and the direct liquefaction performance of coal needs to be evaluated, the controller executes Step S101 to obtain real-time influence factor information. The real-time influence factor information refers to the factors that affect the direct liquefaction performance of coal during the direct liquefaction reaction process. The real-time influence factor information includes coal factor information, catalyst factor information, hydrogen-donating solvent factor information, and reaction condition factor information; then executes Step S102 to input the real-time influence factor information into a preset target evaluation model to obtain liquefaction performance evaluation indicators. The target evaluation model is trained by using linear regression algorithm, random forest method, light gradient boosting algorithm, and extreme gradient boosting algorithm; finally executes Step S103 to determine the direct liquefaction performance of coal according to the liquefaction performance evaluation indicators. For example, the higher the conversion rate, oil yield, water yield, gas yield, and asphaltene yield, and the lower the hydrogen consumption, the better the direct liquefaction performance of coal, thus realizing a rapid, effective, and accurate evaluation of the direct liquefaction performance of coal, and at the same time providing a guiding role for the regulation of the direct liquefaction experiment through the liquefaction performance evaluation indicators.

[0049] In this embodiment, by obtaining the real-time influencing factor information that determines the direct coal liquefaction performance, inputting the real-time influencing factor information into a preset target evaluation model to obtain a liquefaction performance evaluation index, and determining the direct coal liquefaction performance according to the liquefaction performance evaluation index, it is possible to quickly, effectively, and accurately evaluate the direct coal liquefaction performance with multiple influencing factors in a short time, which plays a guiding role in the regulation of direct coal liquefaction experiments.

[0050] In one embodiment, after step S101, it further includes:

[0051] Processing the real-time influencing factor information by deletion method and interpolation method to obtain sub-target influencing factor information;

[0052] Performing one-hot encoding and sequence encoding on the qualitative variables in the sub-target influencing factor information to obtain target influencing factor information, where the qualitative variable is the classification information in the sub-target influencing factor information.

[0053] Specifically, preprocessing the missing, repeated, and abnormal real-time influencing factor information by deletion method and interpolation method to obtain more accurate influencing factor information, and then using one-hot encoding to convert n real-time influencing factor information and d variables of different categories into d binary variables, which formally looks like an n-row d-column boolean matrix (a matrix with all elements being 0 or 1), and using sequence encoding to assign a unique integer value to each category in the qualitative variable, so as to realize the encoding of qualitative variables for the real-time influencing factor information, which is convenient for the target evaluation model to identify. The qualitative variables include catalyst, promoter, sulfur additive, catalyst type, and hydrogen-donating solvent.

[0054] In one embodiment, the coal factor information includes proximate analysis, ultimate analysis, ash composition analysis, and maceral analysis, the catalyst factor information includes catalyst, catalyst addition amount, promoter, sulfur additive, catalyst type, and sulfur-iron molar ratio, the hydrogen-donating solvent factor information includes hydrogen-donating solvent, coal-solvent ratio, and solvent element composition, and the reaction condition factor information includes reaction temperature, reaction pressure, and isothermal time.

[0055] Based on the above embodiment, as Figure 2 shown, another embodiment of the present invention provides a method for evaluating the direct coal liquefaction performance, including:

[0056] Step S201: Obtain historical influencing factor information;

[0057] Step S202: Divide the historical influencing factor information into a training set and a test set;

[0058] Step S203: Use the linear regression algorithm, random forest algorithm, light gradient boosting algorithm, and extreme gradient boosting algorithm to train the training set, and construct the corresponding linear regression training model, random forest training model, light gradient boosting training model, and extreme gradient boosting training model;

[0059] Step S204: Use the test set to test the linear regression training model, random forest training model, light gradient boosting training model, and extreme gradient boosting training model to obtain the linear regression model, random forest model, light gradient boosting model, and extreme gradient boosting model;

[0060] Step S205: Use the coefficient of determination, mean squared error, root mean squared error, and mean absolute error to evaluate the model fitting performance of the linear regression model, random forest model, light gradient boosting model, and extreme gradient boosting model;

[0061] Step S206: Determine the model with the largest coefficient of determination and the smallest mean squared error, root mean squared error, and mean absolute error as the target evaluation model;

[0062] Step S207: Obtain real-time impact factor information;

[0063] Step S208: Input the real-time impact factor information into the target evaluation model to obtain the liquefaction performance evaluation index;

[0064] Step S209: Determine the direct coal liquefaction performance according to the liquefaction performance evaluation index.

[0065] Specifically, when it is necessary to evaluate the direct coal liquefaction performance, the controller executes steps S201 - S204 to construct a linear regression model (MLR), random forest model (RF), light gradient boosting model (LightGBM), and extreme gradient boosting model (XGBoost). As shown in Table 1 below, the training and validation results of different models for the training set and test set (only one combination of influencing factors).

[0066] Table 1 Training and validation results of different models on the training set and test set

[0067]

[0068]

[0069] Then, the controller executes steps S205 - S206 to compare the coefficient of determination (R 2 ), mean squared error (MSE), root mean squared error (RMSE), and mean absolute error (MAE) of different models to evaluate the model fitting performance, where R 2The result is between 0 and 1. The closer the result is to 1, the better the fitting performance of the model. Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and Mean Absolute Error (MAE) etc. represent the error between the predicted value and the true value. The smaller this value is, the better the fitting performance of the model. The model with the largest determination coefficient and the smallest mean squared error, root mean squared error, and mean absolute error is determined as the target evaluation model.

[0070] Finally, steps S207 - S209 are executed to determine the direct coal liquefaction performance, so as to realize a rapid, effective, and accurate evaluation of the direct coal liquefaction performance. At the same time, the liquefaction performance evaluation index plays a guiding role in the regulation of the direct coal liquefaction experiment.

[0071] In this embodiment, by constructing a target evaluation model, a rapid, effective, and accurate evaluation of the direct coal liquefaction performance using multiple influencing factors within a short time is realized, which plays a guiding role in the regulation of the direct coal liquefaction experiment.

[0072] In one of the embodiments, after step S204, it further includes:

[0073] Using the grid search method and the cross - validation method to optimize the model parameters of the linear regression model, random forest model, light gradient boosting model, and extreme gradient boosting model respectively.

[0074] Specifically, the grid search method systematically traverses all possible combinations of the set parameters to find the best parameter combination; the cross - validation method divides the training set data into five parts (five - fold), and each part takes turns as the validation set, while the other four parts are used for training to ensure the model performance and improve the generalization ability of the model in actual applications.

[0075] In one of the embodiments, the real - time impact factor information is determined by the following method:

[0076] Arrange and combine the historical impact factor information in ascending order to obtain a historical information set;

[0077] Input the historical information set into the linear regression model, random forest model, light gradient boosting model, or extreme gradient boosting model respectively to obtain the importance ranking and Shapley values of the historical information set;

[0078] Determine the real - time impact factor information according to the importance ranking and Shapley values.

[0079] Specifically, the historical impact factor information is analyzed using the contribution degree analysis method to determine the impact factor information. Specifically: variable importance analysis and Shapley additive explanation are respectively used. Variable importance analysis can obtain the order of the contribution degree of impact factors to the liquefaction performance, understand which impact factors have the greatest contribution degree to the liquefaction performance, and which impact factors have a very small contribution degree to the liquefaction performance; Shapley additive explanation assigns a data to the contribution of each impact factor in the model to the direct coal liquefaction performance, so as to understand how each impact factor affects the evaluation index of the direct coal liquefaction performance, and then judge and adjust the priority of the impact factors affecting the direct coal liquefaction performance of the reactor to determine the impact factor information.

[0080] In one embodiment, to improve the accuracy of the target evaluation model, step S202 includes:

[0081] The historical impact factor information is divided into a training set and a test set according to 8:2.

[0082] The following is an example to illustrate the evaluation of the direct liquefaction performance of the reactor under different reaction conditions. The catalyst is selected as Fe 2 O 3 , the hydrogen-donating solvent is tetralin, the catalyst addition amount is 3%, n S :n Fe is 2, the coal dissolution ratio is 3, and the above-mentioned direct coal liquefaction performance evaluation method is used to obtain the evaluation results shown in Table 2 below.
