1,232,449. Catalytic apparatus. PULLMAN Inc. 8 Aug., 1968 [18 Aug., 1967], No. 28031/ 68. Heading B1F. In apparatus for catalytic ammonia or methanol synthesis involving heat exchange at heat exchanger 19 between reactants introduced at 50, and hot products withdrawn at 52, the reactants pass along annular chamber 18 into heat exchanger 19, thence through charge line 51 to meet quench gas from 41 in perforated distributor 46. The gas mixture then passes down catalyst bed 14, up chamber 38, down catalyst bed 15, up the next chamber 38, and so on through beds 16 and 17 to reach heat exchanger 19. Quench gas may be introduced via pipe 41, or via concentric perforated pipes 42, 43, 44 to mixing chambers below the catalyst beds. Thermocouples 49 measure the temperature in the catalyst beds. |
