ABSTRACT:
A joint process for preparing alcohol/ether mixtures, alcohol/hydrocarbon mixtures and synthesizing ammonia is disclosed. In particular, a process of converting CO and CO2present in the feed gas of ammonia synthesis, comprising H2and N2as major components, into useful co-products is disclosed. The process is characterized in that the alcohol/ether forming reaction is firstly carried out by using a copper series catalyst, then the alcohol/hydrocarbon forming reaction is carried out by using an iron series 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 and CO2is less than or equal to 10 ppm, is fed into the ammonia synthesis system. Since the alcohol/hydrocarbon can be used as liquid fuel, the product composition of the ammonia plant is improved, and the amount of CH4fed into the ammonia synthesis system is decreased, and the amount of venting is thus reduced.
