Countercurrent hydroprocessing with feedstream quench to control temperature

A process for upgrading a liquid petroleum or chemical stream wherein said stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. Injecting feed into one or more downstream reaction zones controls the temperature of at least one reac...
