Improvements in hydrocarbon processing.

摘要

A mixture of C10 to C14 aromatic hydrocarbons, e.g., resulting from a synthesis reaction, is upgraded to lower alkyl benzenes by passing the mixture over an aluminosilicate catalyst together with a catalytic additive, which can be recovered for re-use. At least an equivalent weight of catalytic additive is used and the upgrading is carried out in the vapour phase.
