甲醇合成气中羰基金属化合物对催化剂的影响及对策

Effects of metal carbonyl to methanol synthesis catalysts in synthesis gas and countermeasures to them

羰基铁、羰基镍是导致铜基合成甲醇催化剂中毒的物质。详细论述了羰基铁、羰基镍的形成机理及对甲醇催化剂的影响,指出使用脱羰基铁、羰基镍吸附剂是延长催化剂使用寿命,提高甲醇产品质量的有效措施。

Iron and nickel carbonyls can deactivate the copper-based catalyst for methanol synthesis. The formation mechanism of iron and nickel carbonyl and their influences on the methanol catalyst are reviewed in detail in this paper. It is pointed out that the use of adsorbents to remove iron and nickel carbonyl is an effective measure to prolong the life of synthetic catalyst and improve the property of methanol product.
