摘　　要：以焦炉气为原料生产甲醇是焦炉气利用的一个重要方向。焦炉气经净化、转化后作为甲醇生产的新鲜气,气体中氢碳比高,大量的氢气不能被充分利用。煤气经变换、脱碳后作为新鲜气生产甲醇,气体中氢碳比偏低。转化气与脱碳气混合,气体的氢碳比得到调节。甲醇生产中,调整两种气体比例,使新鲜气组成达到最佳。甲醇合成的弛放气中氢气含量很高,利用膜分离或变压吸附技术对弛放气进行回收以达到有效利用。Methanol synthesis plays an important role in the utilization of coke-oven gas. The H/C ratio of the syngas prepared from coke-oven gas by purification and reforming is too high, so hydrogen couldn＇t be fully used. The decarbonization gas prepared by shift reaction and decarbonization of coal gas has low H/C ratio. Therefore, the H/C ratio could become appropriate for methanol synthesis when the two kinds of gases are mixed by regulating and optimizing the ratio of two feed gases. Methanol synthesis exhaust gas is rich in hydrogen which could be effectively recovered and utilized by the technology of membrane separation or pressure swing adsorption.
