FIELD: petrochemical processes and catalysts.
SUBSTANCE: invention relates to processes for hydrocarbon feedstock conversion into aromatic hydrocarbons, in particular to light hydrocarbon aromatization process catalysts, to catalyst preparation processes, and aromatic hydrocarbon production processes. A composite light hydrocarbon aromatization process catalyst is described, which contains acidic microporous component with pore size at least 5 Å and oxide component exhibiting dehydrogenation activity and selected from aluminum hydroxide and/or oxide having transportation pore size at least 20 nm, said oxide component having been treated with promoter element compounds. Described are this catalyst preparation method and aromatic compound production process in presence of above-described catalyst.
EFFECT: increased activity and selectivity regarding formation of aromatic hydrocarbons and stabilized functioning of catalyst.
