MANUFACTURE OF AROMATIC COMPOUNDS FROM ETHANE AND/OR ETHYLENE

摘要

The present invention relates to a process for producing aromatic hydrocarbons from a hydrocarbon feedstock rich in C2 hydrocarbons. In particular it is a process for producing aromatic hydrocarbons comprising bringing into contact at a temperature between 580 DEG C and 750 DEG C hydrocarbon feedstock containing at least 70% by weight of C2 hydrocarbons with a catalyst composition comprising an aluminosilicate having gallium deposited thereon and/or an aluminosilicate in which cations have been exchanged with gallium ions, said aluminosilicates containing silica to alumina in a molar ratio of at least 5:1. The process affords a one-step method of upgrading C2 feedstock into aromatics.
