Abstract

This paper first examines the five kinds of heavy oil, including Lungu atmospheric residue (LGAR), Du-84 super heavy oil (Du-84), the islands of less the slag (GDVR) of Daqing Residue (DQVR) and Liaohe vacuum residue (LHVR) between Inner Mongolia lignite, bituminous coal hydrogenation Shenhua of adaptability, effects of N, N dimethyl formamide (DMF) swelling of coal, the traditional iron catalyst loading and DMF the Swelling load iron catalyst blending the two with heavy oil co-processing. Introduced chemical pointer the anthracene to reveal coal - heavy oil hydrogenation refining hydrogenation performance and several heavy oil for hydrogen performance swelling effect, both traditional loading iron catalyst and swelling load iron catalyst preparation system hydrogenation performance, initially revealed coal - heavy oil refining matching reasons. Investigation of the adaptability of coal - heavy oil refining: five kinds of heavy fuel oil and coal between different adaptability. DMF swelling effect can significantly promote coal liquefaction performance - heavy oil hydrogenation total refining, but there are some differences in the effect of different heavy oil - coal system, which oil for LGAR Du-84 with a total refining the promoting effect of the system obvious. The traditional supported iron catalysts can play a very good catalyst to promote a system of liquefied yield its hydro-liquefaction effect is obvious than with DMF swelling promoting effect; compared with traditional iron catalyst loading by DMF swelling the iron catalyst load method liquefaction better, Du-84-Inner Mongolia lignite liquefaction rate of the system up to 88%. The introduction of chemical pointer anthracene: heavy oil for hydrogen performance is not the only key factor in control of of total refining the heavy oil and coal hydrogenation for hydrogen heavy oil is not necessarily with the coal hydrogenation solvent refining. The presence of a gas phase molecular hydrogen, with oil for hydrogen has increased, and is conducive to the molecular hydrogen to the PAHs, the hydrogen transfer process. DMF swelling action processing Blending chemical probes anthracene in the hydrogenation of heavy oil with coal hydrogenation of refining capacity can be improved, thereby suppressing the polycondensation reaction of the coal, to reduce the formation of coke. Compared with traditional iron catalyst loading, the swelling load iron catalyst, not only can improve the index of hydrogenation of the chemical probe anthracene total refining system, but also to achieve the the Chemical pointer anthracene depth hydrogenation octahydro anthracene. This indicates that the presence of iron catalyst in the swollen load coal - oil refining hydrogenating ability of the system is better, thus promoting the coal - heavy oil refining reaction is transformed to a higher liquefaction rate.
