Abstract
The results of the catalytic hydroconversion of oil shale pyrolysis tar in the presence of in situ and ex situ synthesized ultradispersed and nanosized MoS2 particles in a flow reactor at a hydrogen pressure of 7MPa, a temperature of 430–450°C, a feed space velocity of 1–2.9 h–1, and an H2/feed flow ratio of 1000 L(NTP)/L with and without recycling the unconverted residue are reported. The optimum conditions of hydroconversion under which the yield of distillate fractions was 91.9 wt % on a raw material basis are proposed. It is shown that the quality of the refined synthetic oil makes it possible to use it in traditional petrochemical processes.
