Process for the conversion of linear butenes to propylene.

摘要

A process for the conversion of olefins having from 4 to 12 carbon atoms into propylene, characterized in that said olefins are brought into contact with a zeolitic compound (optionally in admixture with a binder), selected from silicalites, boralites, chromosilicates and those zeolites ZSM5 and ZSM11 in which SiO2/Al2O3 (by moles) is >/= 350, at a space velocity of from 5 to 200 kg/h of olefins per kg of pure zeolitic compound (binder excluded) and at a temperature of from 400 to 600 DEG C, said zeolitic compound being used as such or in a modified form.
