A JOINT PROCESS FOR PREPARING ALCOHOL-ETHER, ALCOHOL- HYDROCARBON AND SYNTHESISING AMMONIA

摘要

A joint process for preparing alcohol-ether, alcohol-hydrocarbon and synthesising ammonia is disclosed. In particular, a process of converting CO and CO2 present in feed gas of ammonia synthesis comprising H2 and N2 as major components, into useful coproducts is disclosed. The process characterized in is that the alcohol-ether formed reaction is firstly carried out by using copper group catalyst, then the alcohol-hydrocarbon formed reaction is carried out by using iron group catalyst, the individually formed alcohol-ether and alcohol-hydrocarbon products are separated by water cooling and condensing, and discharged into corresponding storage tanks, and the remaining gas, in which the amount of CO+CO2 is less than or equal to 10ppm, is feed to ammonia synthesis system. Since the alcohol-hydrocarbon can be used as liquid fuel, the product composition of ammonia plant is improved, and the amount of CH4 feeded into ammonia synthesis system is decreased, and the amount of venting is thus reduced.
