醇烃化工艺在联碱厂的应用

Use of Methanolization-Hydrocarbylation Process in Integrated soda Plant

采用铜-锌-铝系甲醇催化剂和铜-铁系烃化催化剂，合成氨原料气醇烃化精制工艺。在联碱生产工艺中应用成功。通过连续2年的运行，CO＋CO2含量可降至（3-5）×10^-6，运行状况良好。

The final purification by the methanolization-hydrocarbylation process of the ammonia feedgas is used successfully in an integrated soda plant with copper-zinc-aluminum based methanol catalyst and copper-iron based hydrocarbylation catalyst. Through two years of continuous operation, the CO ＋ CO2 content can be decreased to （3 ～5） × 10^-6, and the plant runs smoothly.
