BRICC heterogeneous phase suspended bed reactor hydroconversion process for mid-low temperature coal tar
Abstract：In order to improve the utilization efficiency of inferior quality heavy oil containing lots of sulfide,nitride,oxide,metal and other heteroatom which weren't treated by fixed bed technology,the BRICC ( Beijing Research Institute of Coal Chemistry) heterogeneous phase suspended bed reactor hydroconversion process was adopted. The research and development background,technical route and characteris-tics,technical progresses about BRICC heterogeneous phase suspended bed reactor hydrogenation process for mid-low temperature coal tar were elaborated. According to the characteristics,the various existing coal tar hydrogenation technologies were divided into four categories and the advantages and disadvantages of each technology were discussed. The difference between heterogeneous phase suspended bed reac-tor hydrogenation process for mid-low temperature coal tar and other existing technology was analyzed. The continuous operation of 200 kg/d experimental device showed that the BRICC technology was suitable for treatment of coal-tar heavy oil with high impurity content. With this technology,the different processing routes were used in accordance with the quality and grade oil. The yield of liquid product was above 90% which was an advanced technology of coal tar deep processing.
