BISMUTH- AND PHOSPHORUS-CONTAINING CATALYST CARRIERS, REFORMING CATALYST BASED THEREON, PREPARATION METHOD, AND PETROLEUM REFORMING PROCESS Russian patent published in 2007 - IPC B01J21/04 B01J27/192 B01J23/644 B01J23/36 B01J27/10 C10G35/85 C10G35/09 

FIELD: petroleum processing and catalysts.

SUBSTANCE: invention relates to bismuth- and phosphorus-containing catalyst carriers, petroleum reforming catalysts prepared on these carriers, to methods for preparing both carriers and catalysts, and to petroleum reforming process using these catalysts. Described are catalyst carrier containing γ-alumina particles wherein bismuth and phosphorus are distributed essentially uniformly in catalytically efficient concentrations and a method for preparation thereof comprising (a) preparing solution containing bismuth precursor and solution containing phosphorus precursor; (b) preparing γ-alumina/alumina sol mixture; (c) mixing mixture of step (b) with solutions prepared in step (a) to produce carrier precursor containing essentially uniformly distributed phosphorus and bismuth; (d) molding; and (e) drying and calcination. Invention also describes petroleum reforming catalyst containing above-defined carrier and catalytically efficient amount of platinum, chlorine, and optionally rhenium; method of preparation thereof; and petroleum reforming process after hydrofining, which involves contacting petroleum with above-defined catalyst in presence of hydrogen at elevated temperature and pressure.

EFFECT: reduced catalyst coking velocity and achieved high stable activity of catalyst.
