Activity of Zeolites of Different Types in n-Alkane Cracking in a Three-Phase Reactor

Abstract

The catalytic activity of zeolites of three types—Y, ZSM-5, and Beta—in the cracking of С₂₀–С₃₅n-alkanes in a three-phase reactor has been studied under the following conditions: a temperature of 300–380°C, a hydrogen pressure of 7 atm, and a catalyst content of 1 wt %. It has been shown that the activity of zeolite Beta in cracking reactions is several times higher than the activity of zeolites of the other types. This finding can be apparently attributed to a large mesopore volume in the Beta structure.
