HYDROGENATION CATALYSTS WITH BINDER THAT FEATURE SMALL SURFACE AREA Russian patent published in 2013 - IPC B01J21/12 B01J29/06 C01B39/02 

FIELD: process engineering.

SUBSTANCE: invention relates to hydrocarbon dewaxing catalysts. Proposed dewaxing catalysts comprise zeolite with silicon dioxide-to-aluminium oxide ratio of 100 or less, combined with binder of metal oxide or aluminium silicate. Prior to catalyst moulding, aforesaid binder has surface area of 80 m²/g or smaller. Applied catalyst features zeolite surface area-to-outer surface area ratio of, at least, 80:100. In compliance with one version, used is zeolite with pores formed by 10-link rings.

EFFECT: higher catalytic activity.
