PROCESS OF PRODUCING DARK PETROLEUM-POLYMER RESIN Russian patent published in 2004 - IPC

Abstract RU 2231530 C1

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^оС-dry point at temperature 150-210^оС 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 γ-alumina carrier. Distilling off liquid hydrocarbons produce dark petroleum-polymer resin with softening temperature 80-95^оС, yield 43-58%.

EFFECT: increased yield of resin and reduced power consumption.
