Hydroisomerization catalyst as well as preparation method and application thereof

The invention discloses a hydroisomerization catalyst as well as a preparation method and application thereof, and belongs to the technical field of catalysts. The catalyst comprises the following rawmaterials: a carrier, a noble metal and a rare earth element. The carrier comprises aluminum hydroxide dry glue, an HY molecular sieve and an HZSM-5 molecular sieve, the aluminum hydroxide dry glue accounts for 26%-43% of the total weight of the carrier, the HY molecular sieve accounts for 49%-63% of the total weight of the carrier, and the HZSM-5 molecular sieve accounts for 7%-21% of the totalweight of the carrier. The noble metal accounts for 0.1%-1% of the total weight of the carrier. The rare earth element accounts for 1%-4% of the total weight of the carrier. According to the hydroisomerization catalyst provided by the invention, the conversion rate and isomerization selectivity of n-alkanes can be effectively improved, and the cracking rate is low. 本发明公开了一种临氢异构化催化剂及其制备方法和应用，属于催化剂技术领域。所述催化剂包括如下原料：载体、贵金属和稀土元
