一、引言在对合成氨厂原料气的净化研究中,用于脱除有机硫化物的固体脱硫剂,目前有活性炭、分子筛、氧化铁、氧化锌、氧化锰以及钼酸钴、钼酸镍和钼酸铁等。有些固体脱硫剂已能成功地用于工业生产,但对其脱硫反应过程往往还不十分清楚。这一方面是因为原料气中所含的有机硫形态复杂繁多,反应过程也非常复杂,另一方面那种模拟工业条件的一般反应器也不适宜进行这种较深入的研究。随着催化学科的 I. INTRODUCTION In the purification of feed gas for ammonia plant, there are activated carbon, molecular sieve, iron oxide, zinc oxide, manganese oxide and cobalt molybdate, nickel molybdate and molybdenum Acid iron and so on. Some solid desulfurizer has been successfully used in industrial production, but the process of its desulfurization reaction is often not yet clear. This is partly because the organic sulfur contained in the feed gas has a complicated and complicated form and the reaction process is very complicated. On the other hand, the general reactor simulating the industrial conditions is not suitable for such deeper research. With the catalytic discipline
