Abstract:

利用C守恒原理对煤制甲醇及下游产品过程CO_2排放点进行分析,对比了选用不同气化原料生产单位甲醇CO_2排放量,得出气化原料多元化对降低CO_2排放量有利的结论。计算出典型煤制甲醇及下游产品过程中各主要排放点的大致排放量比例,可知燃料燃烧排出的CO_2占总排放量的比重较大,甲醇合成过程排出CO_2浓度较高,适于后续加工利用。 Research on CO_2 emission during making methanol and it's downstream products from coal based on carbon conservation principle.Diversification of gasification raw materials can decrease CO_2 emission according to test the changes of CO_2 emission while taking different gasification raw materials.Calculate approximate CO_2 emission rules in each main emission process,find that the burn of raw materials discharges most CO_2,while methanol synthesis process discharges the highest concentration of CO_2
