Effects of Hydrogen Donor and Hydrogen on Thermal-, Hydro-, and Catalytic Hydro-cracking of Subfractions of LiaoHe Residue

摘要

Hydrogen donors and hydrogen with/without dispersed catalysts can provide the activation hydrogen atom when heated together with vacuum residue, have been used in order to improve upgrading of feed. The former report~([1-5]) show the hydrocracking of residue could be improved by the combination of dispersed catalysts and hydrogen donors in comparison with pure dispersed catalysts. The aim of this work is to investigate the effect of hydrogen donors and hydrogen in the hydrocracking reaction systems of subfractions of LiaoHe residue with the combination of dispersed catalyst and H-donor and to study the synergism between hydrogen donors and dispersed catalysts in slurry-bed hydrocracking.
