摘　　要：由于焦炉煤气氢碳比高于甲醇合成的理想比例,使生产规模受到限制。大量过剩氢存在于驰放气中,降低了氢资源的利用率。采用氢碳摩尔比低的气源,与焦炉煤气双气制甲醇可以解决这一问题。从氢碳比和实际应用角度对此进行了分析,并对某煤化工企业甲醇补碳的合理性及可行性进行了论证。The methanol production scale is limited because the hydrogen-carbon ratio of coke oven gas is higher than the ideal ratio of methanol synthesis. A large number of excess hydrogen exists in the tail gas and reduces the efficiency of hydrogen utilization. This problem could be solved by using the gas of low ratio of hydrogen to carbon and coke oven gas for producing methanol. In this paper,the analysis is made from the point of the practical application of the ratio of hydrocarbon. Furthermore, the reasonability and feasibility of adding carbon for methanol in a coal chemical enterpris is discussed.
