摘要：Facing the rapid growth of the demand for aromatic hydrocarbons, combined with China's energy development status of "coal-rich, lean oil, and low gas", the methanol-to-aromatics (MTA) process has good development prospects. In this paper, the influence of reaction temperature, space velocity, and other conditions on the reaction performance of methanol-coupled light hydrocarbons to aromatics was investigated and then a lumped reaction kinetics study was carried out. The results of the study are: To investigate the composition and distribution of the products obtained by the reaction, according to the needs of lumped reaction kinetics research, six lumped mixed raw materials, C1, olefin alkanes, and aromatic hydrocarbons classified by different categories were constructed; based on the MTA reaction mechanism, assuming each reaction series, the reaction network and lumped kinetic equations were established; simplex algorithm and the Levenberg-Marquardt optimization method were used to fit the regression to obtain the kinetic model parameters; through the statistical test calculation of the model, each set of the overall decisive indicators are all greater than 90% and F > 10F(0.05), so the established kinetic model of methanol-coupled light hydrocarbon to aromatics is suitable.
