METHOD OF MAKING MEMBRANE CATALYST AND METHOD OF HYDROCARBON DEHYDRATION USING OBTAINED CATALYST Russian patent published in 2013 - IPC B01J21/18 B01J23/40 B01D71/00 B82B3/00 C07B35/04

Abstract RU 2497587 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production and application of hydrocarbon dehydration catalysts. Proposed catalyst represents a stainless steel, nickel or copper substrate with one side coated with polyacrylonitrile (UV-PAN) pyrolised by UV radiation. Opposite side of said substrate has the layer containing nanoparticles of alloys Pt-Ru, Pt-Re, Pt-Rh or Pd-Ru distributed in UV-PAN film. Proposed method comprises application of PAN layer of its solution in organic solvent on said substrate, draying, irradiation by UV light and application on opposite side of precursor, i.e. combined solution of PAN with compounds of Pt or Pd c Ru or Re or Rh at the ratio of Pt(Pd):Ru(Re,Rh)=(7÷10):1 with introduction of fine carbon material into said solution. It includes also the stepwise irradiation by UV light of definite intensity at every step and cooling. Method of hydrocarbon dehydration is implemented at the plant with through-flow membrane reactor wherein obtained catalyst divides the plant into dehydration zone and that wherein hydrogen selectively diffuses.

EFFECT: higher efficiency and catalyst stability, efficient dehydration.
