Catalytic Conversion of Chloromethane to Methane and Propane on SiO2/Al2O3: Kinetics of Deactivation Caused by Coking

Leopoldo O. A. Rojas, João F. Sousa, Juan A. C. Ruiz & Márcio B. D. Bezerra · Chemical Science International Journal · 2016

Chloromethane was catalytically converted into methane and propane in a fixed-bed reactor with control of pressure and flow rates. The deactivation by coking was studied in a microadsorber equipped with gravimetric monitoring. In this study, two models are proposed: the first one...
