Process for the production of aromatic hydrocarbons from aliphatic hydrocarbons.

摘要

Aromatic hydrocarbons are produced by catalytic conversion of aliphatic hydrocarbons using an aluminogallosilicate catalyst. A feed of the aliphatic hydrocarbon is mixed with a recycle gas and the mixture is contacted with the catalyst. The resultant conversion product is separated into a gas phase and a liquid phase containing aromatic hydrocarbons. The gas phase is separated into a hydrogen-rich gas and a methane- and/or ethane-rich gas while the liquid phase is separated into an aromatic hydrocarbon-containing product and a light hydrocarbon-containing gas. At least part of the methane- and/or ethane-rich gas and the light hydrocarbon-containing gas is recycled as the above recycle gas. The catalytic conversion is performed while increasing the reaction temperature as the process proceeds.
