摘　　要：本实验以煤和石油渣油(1∶1)为主要原料,进行共处理反应研究.概述了进行该反应在不同条件下反应产物的性质评定,指出由于温度、反应时间等实验条件的不同,重质产物的性质存在着很大的差别.随着反应温度的变化,催化裂化油浆与兖州煤共处理的重质产物族组成呈规律性的变化,重质产物性质与高等级道路沥青近似,由此试验可看出,重质产物有望用于制备高等级道路沥青.The co-processing reaction of coal and catalytic residue(CCR),especially the heavy toluene soluble fractions(HTSF) produced were studied in a autoclave when the ratio of coal to CCR is 1∶1. The yield of HTSF is the highest among the other products.The properties of the HTSF changes regularly with the variation of reaction temperature and time. Group composition of HTSF from co-processing of coal and CCR changes regularly with some rules. Characters of HTSF and the asphalt are approximative. It may be used as high grade paving asphalt for highway and a pitch precursor of carbon artifacts.
