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 m/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.16 cl, 5 dwg, 1 tbl, 8 ex |
