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 10ppm, 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.

La présente invention concerne un processus lié de préparation d'alcool-éther, d'alcool-hydrocarbure et d'amoniac de synthèse. Cette invention concerne, en particulier, un processus de transformation de CO et de CO¿2 ?présents dans un gaz d'amoniac de synthèse comprenant H¿2? et N¿2? comme composants principaux, en des coproduits utiles. Ce processus se caractérise en ce que la réaction formés d'alcool-éther est d'abord menée par utilisation d'un catalyseur du groupe cuivre, puis la réaction formée d'alcool-hydrocarbure est menée par utilisation d'un catalyseur du groupe fer, les produits alcool-éther et alcool-hydrocarbure formés individuellement sont séparés par une eau de refroidissement et de condensation et évacués dans des réservoirs correspondants, le gaz restant, dans lequel la quantité de CO+CO¿2? est inférieure ou égale à 10ppm, est alimenté dans le système de synthèse d'amoniac. Comme on peut utiliser l'alcool-hydrocarbure comme combustible liquide, la composition de produit d'usine d'amoniac est améliorée et, la quantité de CH¿4? alimentée dans le système de synthèse d'amoniac est diminuée et la quantité de dégazage en est donc réduite.
