Z型甲烷蒸汽转化催化剂用于补碳制合成甲醇合成气的研究

选择工业应用效果较好的CNYQ、Z-2和Z-3型催化剂，并补加CO₂,对在其上的甲烷水蒸汽转化制合成气催化反应过程进行了测试研究。结果表明，在适当补加CO₂、反应温度600～850 ℃下，制得的合成气适合于甲醇合成。Z型催化剂用于CH₄-H₂O-CO₂转化制合成甲醇合成气，在当前情况下可满足某些合成甲醇厂的需要。

Preparation of methanol synthesis gas by methane steam reforming over Z type catalyst with carbon dioxide supplement

A methane steam reforming test was carried out over CNYQ, Z-2 and Z-3 catalyst, respectively, with supplement of carbon dioxide for preparation of methanol synthesis gas. The test results showed that H₂/CO of the resultant synthesis gas, prepared by steam reforming at 600-850 ℃ with supplement of appropriate amount of CO₂, was suitable for methanol synthesis. Z series catalyst is applicable to preparation of methanol synthesis gas via CH₄-H₂O-CO₂ reforming to meet the need of some methanol synthesis plants.
