Catalytic Pyrolysis of Propane-Butane Hydrocarbon Mixture on the Composite Ceramic Materials in an Open System

摘要

Catalytic pyrolysis of propane-butane hydrocarbon mixture on the composite ceramic materials with the surface modified with zinc-, cadmium- phosphorus- and silicon-containing compounds in an open system was studied in the temperature range 500-850°C, at the rate of the gas mixture flow 20-200 ml min~(-1), contact duration 0.75-155 s, and the values of the heterogeneity factor 2.0 to 2.9X10~5 cm~(-1). The catalytic activity of the systems under similar conditions was compared, the influence of various factors on the yield of ethylene and propylene was investigated and the sooting was estimated.
