Sensitivity of synergism between hydrogen donors and dispersed catalysts in different base residue hydrocracking

摘要

The catalytic hydrocracking processes of vacuum residue with dispersed catalysts have been extensively reported (1) and the catalytic or non-catalytic liquefaction of coal with hydrogen donors have been known for about 70 years(2-3). However, the hydrocracking process of vacuum residue with dispersed catalysts and hydrogen donors have seldom been reported and the process was nearly reported in order to improve upgrading of low quality feed (6).
