    • A joint process for preparing alcohol/ether mixtures, alcohol/hydrocarbon mixtures and synthesizing ammonia is disclosed. In particular, a process of converting CO and CO2 present in the feed gas of ammonia synthesis, comprising H2 and N2 as 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 CO2 is 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 CH4 fed into the ammonia synthesis system is decreased, and the amount of venting is thus reduced.
    • 公开了制备醇/醚混合物,醇/烃混合物和合成氨的联合方法。 特别地,将氨合成的原料气体中存在的CO和CO 2 CO 2转化为主要组分的方法,包括H 2 N 2和N 2 N 2 ,成为有用的共同产品。 该方法的特征在于首先通过使用铜系催化剂进行醇/醚形成反应,然后通过使用铁系催化剂,单独形成的醇/醚和醇/烃来进行醇/烃形成反应 产物通过水冷和冷凝分离,并排放到相应的储罐中,CO和CO 2 CO 2的量小于或等于10ppm的剩余气体进料到 氨合成系统。 由于醇/碳氢化合物可以作为液体燃料,所以氨厂的产品组成得到改善,并且进入氨合成系统的CH 4 N 3的量减少,排气量为 从而减少。
