烟煤与重质油共处理的研究

STUDY ON REACTION PROPERTY OF CO-PROCESSINGBITUMINOUS COALS AND HEAVY OILS

煤与重质油的共处理是最有希望实现“由煤制油”的第三代煤液化新工艺之一。我国目前炼油厂每年有四、五千万吨石油渣油产出，只有一小部分用作制氢或合成气的生产原料以及生产沥青或石油焦，其余大部分用于工业燃料［１］。如将减压渣油与煤进行共处理，共同提质，提高其...

The reaction process of co-processing two bituminous coals with low temperature coal tar distillate (LTCTD) and petroleum residue (PR) from Beijing Yanshan Petrochemical Corporation were studied by using resonance agitation reactor The effects of temperature and types of heavy oils on coals conversion and products including preasphaltene, asphaltene were also investigated When reaction time was 60 min, the highest conversion was obtained at temperatures of 390C and 410C for Yangcun coal and Daliuta coal, respectively The conversion followed the order of both LTCTD>blended heavy oils>PR There is no intensive synergy between LTCTD and PR on coal conversion GC-MS analysis showed that PR mainly consisted of long-chain alkane and LTCTD was mainly derivate of naphthalene Their interactions with coal were discussed
