Influence of the surface on the kinetics of the thermal decomposition of acetylene

Abstract

1. The thermal decomposition of acetylene proceeds according to first or second order, depending upon the nature of the surface of the heat carrier. 2. In the presence of corundum and metallized quartz, at a set degree of conversion of acetylene, the yields of coke and methane are increased, while the yield of benzene is reduced. 3. In the transition from quartz to corundum and metallized quartz, the rate of coke formation increases five- to sevenfold, while the rate of methane formation increases three- to fourfold.
