    Abstract: An apparatus for catalytic distillation consists of alternatively a catalyst unit and an active liquid distributor tray. The catalyst unit is formed by series of troughs containing catalysts with spaces between adjacent troughs for vapor flow. The active liquid distributor tray is preferably a V-shaped tray formed with collectors that function as both a liquid distributor to deliver liquid at the appropriate locations to the underneath catalyst unit and a mass transfer device. Liquid flows down to the catalyst toughs from bottom of the sump of each collector and vapor flows up through the upper diverging walls of the collector. Packing materials may be placed on the tray or in the spaces between the troughs or both to enhance mass transfer. The catalyst troughs preferably are partitioned to cause the liquid to flow through the catalyst and to overflow the upper rim of the troughs to escape therefrom whereby the catalyst is maintained submerged.

    Abstract: A hydrogenation reactor comprises an elongated vertical container with a height greater than twice the width and divided into a plurality of tall slender chambers, either as a new reactor or as a modified existing reactor, having greatly increased distribution of a fluid reactant mixture flowing through a solid catalyst. Vertical baffles divide the container into various novel configurations having an increased height-towidth ratio giving increased linear velocity of the flowing reactants to several times that of the single pass reactor while maintaining the space velocity constant, the baffles further providing high strength-to-weight ratio and greater distribution while still permitting easy loading, regeneration, and dumping of the catalyst. With the last chamber being a downflow chamber in all modifications, catalyst ''''carry over'''' is minimized. Most of the modifications have an even number of chambers with inlet and exit nozzles at the bottoms of both the first chamber and last chamber insuring more efficient reverse flow at any time.

    Abstract: The improved generally-inverted T-shape converter for ammonia synthesis comprises a horizontal high-pressure vessel on which is positioned a vertical high-pressure vessel with free fluid commnication therebetween. Inside these vessels is placed a lowpressure vessel forming one unit also of inverted T-shape geometry similar to that of the high-pressure assembly. The horizontal part of the reactor contains at least two axiallyaligned reaction chambers, within each of which is a catalyst supported on grates forming catalyst beds, and the vertical part contains a heat exchager of which one side is in fluid flow communication with a first one of the reaction chambers, which chambers have serial fluid flow communication, and a second side of the heat exchanger is in fluid flow communication with the second one of said reaction chambers. The space under the catalyst bed of the second reaction chamber is fluidly connected with the second side of the heat exchanger by means of a combined heat-exchanger support and vertical duct resting on the inner surface of the horizontal low-pressure vessel directly, or by means of another support therefor.
