Abstract

A reactor for reacting liquid petroleum or chemical streams wherein the liquid stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas. The reactor is comprised of at least one vertically disposed reaction zone, each containing a bed of catalyst, wherein each reactionzone may contain vapor bypass means, and wherein each reaction zone is immediately preceded by a non-reaction zone, and wherein each non-reaction zone contains a gas/liquid contacting zone for stripping gaseous by-products, such as NH3 and H2S, from the liquid stream.
