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 reaction zone 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 NH.sub.3 and H.sub.2 S, from the liquid stream.

[ What is claimed is:] [1.]1. A reactor for reacting liquid petroleum and chemical streams with a hydrogen-containing treat gas in the presence of a catalyst in at least one countercurrent reaction zone, which reactor comprises:(a) a continuous wall enclosing a countercurrent first reaction zone, wherein said first reaction zone includes a bed of the catalyst, and wherein there is a first non-reaction zone immediately upstream of said first reaction zone and at least a second non-reaction zone downstream of said first reaction zone;(b) a gas-liquid contacting zone within each of said non-reaction zones, which gas-liquid contacting zone contains a contacting means comprised of open-structure solid material;(c) liquid inlet means upstream of said first non-reaction zone of said first reaction zone for allowing an unreacted portion of said liquid stream to enter said reactor;(d) gas inlet means downstream of said first reaction zone for allowing an unreacted portion of treat gas to enter the reactor;(e) liquid outlet means downstream of said first reaction zone for allowing a reacted portion of said liquid stream to exit said reactor;(f) gas outlet means upstream of said first non-reaction zone of said first reaction zone for allowing a reacted portion of said treat gas to exit said reactor; and(g) first gas bypass means in said first reaction zone for allowing at least a portion of the treat gas to bypass said first reaction zone.
