STRAIGHT-RUN GASOLINE FRACTION CATALYTIC REFORMING PROCESS Russian patent published in 2000 - IPC

FIELD: petroleum processing. SUBSTANCE: raw material is first subjected to hydrofining at 280-380 C and pressure 1.5-4.0 MPa on catalyst composed of 2-6% cobalt or nickel oxide, 10-20% molybdenum or tungsten oxide, and carrier: mixture of aluminum, boron, titanium or zirconium, and manganese oxides at weight ratio 1:(0.005-0.053):(0.002-0.042):(0.0004- 0.0015). Refined product is then subjected to reforming at 460-520 C and pressure 1.4-3.5 MPa on catalyst composed of, wt %: platinum 0.2-0.5, rhenium 0.015-0.8, chlorine 0.8-1.4, carrier - the balance, or platinum 0.2-0.5, rhenium 0.015-0.8, chlorine 0.8-1.4, promoter (selected from palladium, iridium, zinc, copper, tin, chromium, phosphorus, and zirconium) 0.02-1.5, and carrier - the balance. EFFECT: stabilized process parameters. 4 cl, 2 tbl, 24 ex
