METHOD OF PRODUCING HYDROCARBON FUEL Russian patent published in 1997 - IPC

FIELD: petroleum processing. SUBSTANCE: oil distillate boiling off within temperature range 140(180)-260(360) C is divided into two streams in weight proportion 5-9 to 1-5. The first stream is subjected to hydrofining at 3-5 MPa and zeolite deparaffinization, and the second one to hydraulic refinement, whereupon obtained products are combined. Hydrofining is conducted at 320-380 C, volume velocity of feed 1-5 h^-1, and hydrogen-containing gas to raw material ratio 250-1000 cu.nm/cu.m. Deparaffinization is conducted at 360-450 C, 0.5-2.0 MPa, and volume velocity of feed 0.5-4.0 h^-1, and hydraulic refinement, respectively, 320-380 C, 3-5 MPa, 1.0-5.0 h^-1. EFFECT: optimized process parameters. 4 cl
