METHOD FOR PRODUCING AROMATIC HYDROCARBONS

WIPO Patent Application WO/2002/066579

A1

The invention relates to organic chemistry, in particular to catalytic methods for producing aromatic hydrocarbons C¿6?-C¿12 ? from hydrocarbons C¿2?-C¿12?. The aim of the invention is to develop an improved method for producing the hydrocarbons characterised by an increased product yield. The inventive method for producing aromatic hydrocarbons consists in transforming a methane mixture with at least one hydrocarbon from the C¿2?-C¿12 ?range¿? in the presence of a porous catalyst. Zeolite having an alumosilicate composition and a molar ratio SiO¿2?/Al2O¿3 ?equal or less than 450 and chosen from a range ZSM-5, ZSM-11, ZSM-35, ZSM-38, ZSM-48, BETA is used as a catalyst. Gallosilicate, galloalumosilicate, ferrum silicate, ferrumalumosilicate, chromosilicate, chromoalumosilicate having a structure ZSM-5, or ZSM-11, or ZSM-48, or BETA, or alumophosphate having a structure of type of ALPO-5, or ALPO-11, or ALPO-31, or ALPO-36, or ALPO-37, or ALPO-40 with elements introduced into structure at stage of synthesis and chosen from the following range: magnesium, zinc, gallium, manganese, ferrum, silicium, cobalt and cadmium are also used as a catalyst. The catalyst for all variants of the method can also contain zinc, and/or gallium, and/or rare-earth elements, or platinum group metals in a quantity equal or less than 10 mass %.
