一种用于由1,1-二氟乙烷制备氟乙烯的铝基催化剂、其制备方法及应用
摘要：
本发明公开了一种用于1,1-二氟乙烷气相脱氟化氢制备氟乙烯的铝基催化剂，含有主要活性组分铝和改性组分，所述改性组分选自镧、钇、铈、锆、锌、镁、镍、钴、铁、锰、锡和铋中的一种、两种或三种以上组合。本发明公开的铝基催化剂能够显著地降低1,1-二氟乙烷气相脱氟化氢制备氟乙烯的反应温度、提高转化率和选择性。
摘要（英）：

The invention discloses an aluminum base catalyst for preparing vinyl fluoride through gas phase hydrogen fluoride removal of 1,1-difluoroethane. The catalyst contains a main active component aluminum and a modification component, and the modification component is one of or a combination containing two or three of lanthanum, yttrium, cerium, zirconium, zinc, magnesium, nickel, cobalt, iron, manganese, tin and bismuth. The aluminum base catalyst disclosed in the invention can substantially reduce the reaction temperature of the preparation of vinyl fluoride through gas phase hydrogen fluoride removal of 1,1-difluoroethane, and improves the conversion rate and the selectivity.
