Abstract
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. The temperature of at least a portion of the liquid stream in the reactor is used to control the flooding characteristics of the reactor.
