An improved process and apparatus for hydrogenating a stream of hydrocarbons is provided. The pressure and temperature of the stream are elevated and the stream is passed through two or more serially connected hydrogenation reaction zones. While passing through the reaction zones hydrogen is dispersed in the stream and the stream is caused to flow along successive downward and upward paths. The reacted stream is cooled prior to reducing the pressure exerted thereon.

Process and apparatus for hydrogenating hydrocarbons

A process for upgrading carbonaceous materials having low carbon content comprising preheating the carbonaceous material to a temperature above about 200.degree. C. in the absence of a solvent, extracting the heated carbonaceous material under moderate temperature and pressure conditions, and hydrotreating the extract under supercritical solvent conditions.
