Abstract
The invention relates to a process for converting a feed stream consisting of reactive components and an optional feed diluent to a product stream comprising aromatic hydrocarbons and C2-C3 olefins, wherein the reactive components comprise at least 90 vol % of an aliphatic ether selected from the group consisting of methyl tertiary butyl ether and ethyl tertiary butyl ether, the process comprising the step of contacting the feed stream with a catalyst composition comprising a zeolite catalyst, wherein the zeolite catalyst is a zeolite modified by Ga and an element M1 selected from the group consisting of Zn, Cd and Cu.

A process for converting a feed stream comprising reactive components and an optional feed diluent to a product stream comprising aromatic hydrocarbons and C2-C3 olefins, the process comprising:
- contacting the feed stream with a catalyst composition comprising a zeolite catalyst, wherein the zeolite catalyst is a zeolite modified by Ga and an element M1 selected from the group consisting of Zn, Cd and Cu;
- and
- converting the feed stream to the product stream comprising aromatic hydrocarbons and C2-C3 olefins, wherein the reactive components comprise at least 90 vol % of an aliphatic ether selected from the group consisting of methyl tertiary butyl ether and ethyl tertiary butyl ether.
A process for converting a feed stream comprising reactive components and an optional feed diluent to a product stream comprising aromatic hydrocarbons and C2-C3 olefins, the process comprising:
- contacting the feed stream with a catalyst composition comprising a zeolite catalyst, wherein the zeolite catalyst is a zeolite modified by Ga and an element M1 selected from the group consisting of Zn, Cd and Cu, wherein the amount of Ga in the zeolite catalyst is 0.1-10 wt %;
- and
- converting the feed stream to the product stream comprising aromatic hydrocarbons and C2-C3 olefins, wherein the reactive components comprise at least 90 vol % of an aliphatic ether selected from the group consisting of methyl tertiary butyl ether and ethyl tertiary butyl ether.
