摘要
脂肪醇是表面活性剂工业的重要基础原料。综述了脂肪酸甲酯加氢制脂肪醇Cu/Zn催化剂的失活研究进展,介绍了Cu/Zn催化剂的烧结、中毒、结焦等主要失活形式的机理,分析了硫、氯、氮、磷、钠的化合物和水、皂、游离脂肪酸、甘油、甘油酯等具有代表性的杂质对Cu/Zn催化剂活性的影响,讨论了Cu/Zn催化剂失活的控制方法。
Fatty Alcohols are important raw materials for surfactant industry. The progress in the study of deactivation of Cu/Zn catalyst for hydrogenation of fatty acid methyl esters to fatty alcohols is reviewed, and the deactivation mechanism related to sintering, poisoning and coking is introduced. The destrucrive effects on the activity of the catalyst of various species, including sulfide, chloride, nitride, phosphide, sodium, water, soap, free fatty acid. glycerine and glyceride are listed. The methods of controlling the deactivation ard discussed.
