摘　　要：为了解决目前固定床加氢技术无法处理的硫化物、氮化物、氧化物、金属等杂原子和杂质含量较高的煤焦油类的劣质重质油的问题,阐述了BRICC(Beijing Research Institute of Coal Chemistry)中低温煤焦油非均相悬浮床加氢技术的开发背景、工艺技术路线、特点及技术进展,把现有各种煤焦油加氢技术根据特点划分为4类,分析每一类技术的优缺点,指出了BRICC中低温煤焦油非均相悬浮床加氢技术与现有其他技术的区别;用200 kg/d规模的连续运转装置的实际运行结果验证了BRICC技术的先进性:BRICC技术适合加工目前固定床加氢技术无法加工的杂质含量较高的煤焦油重质油,根据所加工油品的性质可采用不同的加工路线进行分质分级加工利用,液体产品收率高达90%以上,是目前先进的煤焦油深加工技术。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 characteristics,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 reactor 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.
