Yield and free radical data set of direct coal liquefaction products under the action of different hydrogen sources at 460℃

The Shendong coal was selected as raw material, and four hydrogen-donating solvents, tetrahydro-naphthalene (TH), dihydro-anthracene (DHA), the recycled solvent (RS) used in the Shenhua direct coal liquefaction process, and the mid- distillate (MTD) of the recycled solvent, and a non-hydrogen-donating solvent, anthracene, were selected. The experiment was out in a micro-vibration reactor with a single reaction tube volume of 30 mL.

The coal sample, catalyst, co-catalyst S, and solvent placed in the reaction tube, with n(Fe):n(S) = 1:2 and a coal-to-solvent ratio of 2:1. Threes, Fe2O3, Mo-Co/Fe2O3, and Ni-Mo-Co/Fe2O3, were used, with a Fe addition 3% and a metal content of 1% in Ni-Mo-Co and Mo-Co. After a gas tightness test, the reactor was purged andurized three times to remove air from the reactor.
