摘要
甲烷蒸汽补加二氧化碳催化转化制合成甲醇合成气是利用废弃的CO2 ,使之转化为有用的碳源 ,达到调节合成气中H2 /CO比例的目的 ,从而降低甲烷消耗 ,降低合成气成本 ,使甲醇产品更具市场竞争力。在磁力搅拌内循环无梯度反应器中 ,采用正交表L2 5(5 6 )安排试验 ,在压力 3.0MPa下 ,以温度、甲烷流量、CO2 /烃碳、H2 O/烃碳四种因素为影响因素 ,考察Z - 2催化剂反应的宏观动力学 ,得到了在温度 6 5 0～ 85 0℃范围内的宏观动力学方程式。
The researchers at home and abroad attach much importance to the study on catalyst for methanol syngas by methane steam reforming with supplement of CO 2. One of the reasons is that the preparation can use waste carbon dioxide to convert into useful carbon and reduce the ratio of H 2/CO; the other is that it can reduce the amount of CH 4,therefore, it cuts down the cost, and makes methanol production more competitively. In this study, experiments were done as testing table L 25 (5 6) in the inner circular gradientless reactor by magnetic stirring, the macro-kinetics of Z-2 catalyst were studied under 3.0MPa pressure and by four effect factors——temperature, velocity of CH 4, CO 2/ΣC, H 2O/ΣC, then the macro-kinetics equations within temperature range 600～850℃ were obtained.
