Effect of reaction temperature on hydrotreatment of a recycle solvent in the NEDOL coal liquefaction process was studied from the data obtained by the operation of a 150t/d pilot plant. Hydrotreatment of the recycle solvent was carried out under a hydrogen pressure of 100kg/cm2G over Ni–Mo/Al2O3 catalyst in a fixed bed reactor. As the reaction temperature increased from 290 to 330°C, the hydrogen...
The catalytic activity of pyrite and synthesized α-FeOOH in coal liquefaction was investigated using batch autoclaves with the aim of developing an industrial iron catalyst. The results indicate that the presence of H 2 S helps gaseous hydrogen transferring and prevents deactivation so that the catalyst promotes hydrocracking of coal and hydrogenation of the products. The activity converges...
The article presents the findings of an investigation of the influence of heavy distillate in the recycle solvent in the coal liquefaction process with a 5-L batch autoclave. Concentrating in heavy distillate in the recycle solvent causes an inhibition of the coal liquefaction reaction and the solvent hydrogenation reaction. Increase of gas/slurry ratio in the coal liquefaction reaction and sever...
