Abstract：In order to obtain lower-priced fuel oil,the feasibility of process for co-vis breaking to coal tar or biomass-oil and heavy oil was explored. The vis-breaking technology was mainly used for processing heavy oil from fossil oil,coal tar and biomass-oil mainly depended on the hydro-cracking of light and refined processing. By studying the mechanism of vis breaking to coal tar or biomass-oil and heavy oil, it was concluded that their reaction on vis-breaking had complementary advantages if they were subjected to co- vis breaking. More organ-ic oxygen functional group were presented in coal tar or biomass-oil,they could become hydrogen donors and / or small free radical frag-ments generators with small molecular weight during vis breaking,the hydrogen donors and/ or small free radical fragments were benefit to vs breaking to coal tar or biomass-oil and vis breaking to heavy oil. The co-vis breaking of coal tar or biomass-oil and heavy oil could im-prove the quality of coal tar,biomass oil and heavy oil,and get more light oil fraction,it also could greatly reduce the comprehensive pro-cessing treatment cost of coal tar or biomass-oil and heavy oil.
