1387044 Catalytic reactor CHEMIE LINZ AG 24 May 1972 [24 May 1971] 24529/72 Heading B1F [Also in Division C1] In catalytic high pressure synthesis apparatus e.g. for synthesis of ammonia from nitrogen/ hydrogen mixture, the synthesis gas enters at 1 and passes down the outside of sleeve 3, then upwardly through heat exchanger 5, conduit 13, lower heat exchanger 7, and upper heat exchanger, and then passes outwardly through upper annular catalytic bed 6, down through upper heat exchanger 7, outwardly through middle annular catalytic bed 6, down through lower heat exchanger 7, outwardly through annular catalytic bed 6, downwardly through lower heat exchanger 5 and leaves at 18. The catalyst particle size is preferably less than 3mm. |
