Arthur J Dahlberg, John H Shinn, Joel W Rosenthal, Tim T Chu: Two-step hydroprocessing of heavy hydrocarbonaceous oils. Chevron Research Company, D A Newell, S R La Paglia, S H Roth, June 21, 1983: US04389301 (92 worldwide citation)

A heavy hydrocarbonaceous oil feed is hydrogenated in a two-stage process by contacting the oil with hydrogen in the presence of added dispersed hydrogenation catalyst, suspended in the oil, and porous solid contact particles. At least part of the normally liquid product from the first stage is hydr ...

Disclosed is a two-stage process for the production of clean liquid hydrocarbons from coal. In the process subdivided coal is dissolved in a process derived solvent at a temperature in the range 425.degree.-480.degree. C. The dissolver effluent is passed through a catalytic reactor operating under h ...
