Abstract: In conventional catalyst evaluation, products were off-line analyzed, and only average conversion and product distributions were provided without information about the proceeding of catalyst deactivation. In order to obtain more information from the catalyst evaluation, a new method, continuous pulse micro-reactor chromatography, was proposed and put into practice to observe the deactivation of catalyst. The new method could obtain various evaluation information in 20 min (per run), and it could provide some new understandings about the catalyst performance, which was impossible for the conventional methods. Only 5-30 mg sample was needed, and the test was accurate, fast and economic.
