Abstract
Aromatic hydrocarbons are produced from a feedstock comprising ethane and/or propane and/or butane by the steps of: PA0 (A) reacting the feedstock in the presence of a dehydrocyclodimerization catalyst to produce a product comprising aromatic hydrocarbons, hydrogen and methane, PA0 (B) separating the product of step (A) into an aromatic hydrocarbon fraction, a methane-rich gaseous fraction and a hydrogen-rich gaseous fraction, PA0 (C) feeding all or part of the methane-rich gaseous fraction separated in step (B) to a synthesis gas production unit, thereby to produce synthesis gas, and PA0 (D) contacting the synthesis gas from step (C) together with all or part of the hydrogen-rich gaseous fraction separated in step (B), thereby increasing the hydrogen to carbon monoxide ratio of the synthesis gas, with a Fischer-Tropsch conversion catalyst to produce a hydrocarbon product.
