The invention provides a catalyst performance testing device with real-time monitoring and
data analysis functions, the catalyst performance testing device comprises a filter, a pressure stabilizing valve, a dryer and a testing
assembly, one side of the filter is fixedly connected with the pressure stabilizing valve, one side of the pressure stabilizing valve is fixedly provided with the dryer, one side of the dryer is fixedly provided with the testing
assembly, and the testing
assembly is fixedly connected with the pressure stabilizing valve. The filter is arranged to prevent impurities from entering a
reaction zone of a catalyst to influence the accuracy of catalytic reaction, the pressure stabilizing valve adjusts the pressure of gas or liquid flow to ensure that the pressure in the
system is always kept in a set range, so that the reaction environment is kept stable, and the dryer is arranged to effectively remove unwanted
moisture in the
system; according to the device, various impurities mainly including
thiophene in crude
benzene are completely removed by hydrogenation through a hydrogenation method, all sulfides are converted into H2S, nitrides are converted into NH3, oxides are converted into H2O, unsaturated hydrocarbons are subjected to hydrogenation saturation, and then the impurities are removed by
extractive distillation, so that high-quality
benzene is produced.
