稀土催化的早期研究主要局限于稀土氧化物。60年代初就发现稀土分子筛用作石油裂解催化剂可提高汽油收率。目前,这一含稀土的分子筛催化剂已用于工业生产。此外,将稀土氧化物用于氢氧化、异构化、烷基化、歧化、环 Early studies on rare earth catalysis have mainly been limited to rare earth oxides. In the early 1960s, rare earth zeolite was found to be used as a petroleum cracking catalyst to increase gasoline yield. At present, this rare earth-containing molecular sieve catalyst has been used in industrial production. In addition, rare earth oxides are used for the hydrogenation, isomerization, alkylation, disproportionation, ring
