PARAFFIN HYDROCARBON ISOMERIZATION CATALYST (EMBODIMENTS) Russian patent published in 2007 - IPC B01J29/80 B01J29/68 B01J29/22 B01J29/44 C07C5/27 

FIELD: petrochemical process catalysts.

SUBSTANCE: invention provides paraffin isomerization catalyst containing platinum or palladium and γ-alumina as binding material and zeolite selected from zeolite beta and/or ZSM-5, zeolite beta and/or mordenite, and mesoporous aluminosilicate of the type Al-MCM-41 at following proportions: platinum and/or palladium 0.2-0.3%, zeolite (beta and/or ZSM-5, beta and/or ZSM-12, beta and/or mordenite) 30-60%, mesoporous aluminosilicate 5-20%, and γ-alumina the rest. In another embodiment, catalyst contains composite material BEA/Al-MCM-41, which is mixture of zeolite beta and mesoporous aluminosilicate Al-MCM-41 at following proportions: platinum and/or palladium 0.2-0.3%, composite material BEA/Al-MCM-41 30-60%, zeolite (ZSM-5 or ZSM-12, or mordenite) 0-10%, and γ-alumina the rest.

EFFECT: increased catalyst stability and selectivity with regard to 2,2-dimethylbutane, and reduced catalyst preparation time.
