    摘要: Provided herein are catalysts for dewaxing of a feedstock, the catalyst comprising between about 40 wt.% and about 99.9 wt.% zeolite, between about 0 wt.% and about 40 wt.% binder and at least about 0.1 wt.% noble metal, as well as catalyst systems, methods and products produced using the catalysts. The zeolite having a crystal comprising a largest included sphere less than or equal to about 7,5 angstroms, a largest diffusing sphere greater than or equal to about 5.0 angstroms, and a silica to alumina ratio greater than or equal to about 100:1. The catalyst having a temperature-programmed ammonia desorption ("TPAD") of less than about 0.25 mmol/g.

    摘要: A hydroisomerization catalyst comprising a molecular sieve belonging to the ZSM-48 family of zeolites; an inorganic oxide support; one or more first modifiers selected from Groups 8 to 10; and one or more second modifiers selected from the group consisting of calcium (Ca), chromium (Cr), magnesium (Mg), lanthanum (La), barium (Ba), praseodymium (Pr), strontium (Sr), potassium (K) and neodymium (Nd). The molecular sieve comprises: a silicon oxide to aluminum oxide mole ratio of about 40 to about 220; at least about 70% polytype 6 of the total ZSM-48-type material present in the product; and an additional EUO-type molecular sieve phase in an amount of between about 0 and about 7.0 percent by weight of the total product. The molecular sieve has a morphology characterized as polycrystalline aggregates comprising crystallites collectively having an average aspect ratio of between about 1 and about 8.
