Abstract:
Coke deposition on pentasil zeolite catalysts during MeOH conversion to hydrocarbons at 520° occurred in 3 forms: in a high C-H ratio form on the surface, in a low C-H ratio form on the surface, and in a high C-H ratio form on the active sites in the pores. In contrast, coke deposition at 420° occurred only in 2, high and low C-H ratio forms on the surface of the catalysts. The deactivation rate of the catalysts increased 7 fold as temp. rose from 420 to 520°, due to the coke deposition in the pores. The coke deposited in the pores was not accessible to O and susceptible to removal by HClO4. Each form of the coke deposits had a different superimposed NMR signal and a characteristic DTA curve.
