FIELD: petrochemical processes. ^ SUBSTANCE: dark petroleum-polymer resin is obtained from heavy fraction of hydrocarbon feedstock pyrolysis products. Process consists in catalytic polymerization of pyrolysis product fraction 160-dry point at temperature 150-210 and pressure up to MPa for 0.5-2 h in presence of stationary, loaded into reactor alumino-cobalt-molybdenum catalyst containing 2.0-6.0% CoO and 10.0-18.0% MoO3 on gamma-alumina carrier. Distilling off liquid hydrocarbons produce dark petroleum-polymer resin with softening temperature 80-95, yield 43-58%. ^ EFFECT: increased yield of resin and reduced power consumption. ^ 2 tbl, 9 ex |
