The invention provides a catalyst which has relatively high activity on hydrodeoxygenation and hydroisomerization of paraffin. The catalyst contains a molecular sieve such as SAPO-11, a metal component such as platinum and/or palladium or nickel tungsten sulfide or nickel molybdenum sulfide, and a binder such as gamma alumina. The catalyst shows relatively uniform distribution of high-proportion weak acid sites and metal components on the molecular sieve and the binder. 本发明提供了一种对于链烷烃的加氢脱氧和加氢异构化具有较高活性的催化剂。该催化剂含有分子筛诸如SAPO-11、金属组分诸如铂和/或钯或镍钨硫化物或镍钼硫化物和粘结剂诸如γ氧化铝。该催化剂表现出高比例的弱酸位点和金属组分在分子筛和粘结剂上的相对均匀分布。
