  • Production of aromatics from ethane and/or ethylene
    Patent number: 4899006
    Abstract: The invention relates to a process for producing aromatic hydrocarbons from a hydrocarbon feedstock rich in C.sub.2 hydrocarbons. In particular it is a process for producing aromatic hydrocarbons comprising bringing into contact at a temperature between 580.degree. C. and 750.degree. C. a hydrocarbon feedstock containing at least 70% by weight of C.sub.2 hydrocarbons with a catalyst composition comprising an aluminosilicate having gallium deposited thereon and/or 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 C.sub.2 feedstock into aromatics.
