Inferior Residual Oil Hydrogenation Technology in Boiling-solid Composite Bed From FRIPP

Among them, the fixed bed residual oil hydrogenation technology is mature, simple and reliable, accounting for more than 75% of the current total residual oil hydrogenation processing capacity.The ebullated bed residual oil hydrogenation technology has the advantages of small pressure drop in the reactor bed, uniform temperature distribution, high mass and heat transfer efficiency, and flexible operation.It can effectively solve the problems of short operation cycle in the traditional fixed bed hydrogenation technology when dealing with inferior residual oil feedstock.It is the preferred technology for the efficient conversion of heavy oil at present.Sinopec (Dalian) Research Institute of Petrochemical Industry Co., Ltd. (FRIPP, referred to as "Dalian Institute") started the research on ebullated bed and fixed bed residual oil hydrogenation technology in the 1960s and 1980s respectively, which is the earliest domestic research on residual oil hydrogenation technology scientific research institutions.
