METHOD OF PROCESSING OIL SLIME AND TRAP OILS Russian patent published in 1995 - IPC

Abstract RU 2041861 C1

FIELD: coal chemistry. SUBSTANCE: oil slimes and trap oils were subjected for settling at 60-100 C. Sediment is subjected for oxidative cracking by spraying latter in the closed volume with a mixture of air and steam heated up to 400-500 C for 0.5-6.0 s, cooled, and liquid phase is separated. Oxidative cracking is carried out at the mass ratio sediment air steam 1: (0.2-0.3): (0.05-0.15). Before cracking sediment can be mixed with water-soluble metal salts of transient valency, such as iron, chrome, nickel, cobalt, tungsten taken at concentration 0.02-0.5 wt.-% (as salt). EFFECT: improved method of oil processing. 4 cl, 1 dwg, 1 tbl
