摘要： The invention provides for a process for dewaxing a waxy hydrocarbon feedstock to form a lubricant oil. The invention is also directed to a catalyst system comprising a hydrotreating catalyst upstream of a dewaxing catalyst, used in the dewaxing of a waxy hydrocarbon feedstock to form a lubricant oil. In particular, the invention is directed to a process and catalyst system designed to maintain yield of lubricant oil product. Specifically, the yield of lubricant oil does not decrease more than 2%, at a target pour point, over a dewaxing temperature range. The hydrotreating catalyst helps prevent aging of the dewaxing catalyst and maintains lubricant oil product yield at a target pour point over a wide temperature range. The hydrotreating catalyst comprises platinum, palladium, or combinations thereof on a low acidity inorganic oxide support where acidity is measured by a decalin conversion of less than 10% at 700° F.
摘要翻译： 本发明提供了一种蜡蜡原料脱蜡以形成润滑油的方法。 本发明还涉及包含在脱蜡催化剂上游的加氢处理催化剂的催化剂体系，用于蜡蜡原料的脱蜡以形成润滑油。 特别地，本发明涉及一种设计用于保持润滑油产品的产率的方法和催化剂体系。 具体地说，在目标倾点下，在脱蜡温度范围内，润滑油的收率不会降低2％以上。 加氢处理催化剂有助于防止脱蜡催化剂的老化，并在较宽的温度范围内将润滑油产品的产率保持在目标倾点。 加氢处理催化剂包括铂，钯或其组合在低酸性无机氧化物载体上，其酸度通过在700°F下低于10％的十氢化萘转化率来测量。

摘要： The invention is directed to a method of making a small crystal SSZ-32 zeolite, known as SSZ-32X. The catalyst is suitable for use in a process whereby a feed including straight chain and slightly branched paraffins having 10 or more carbon atoms is dewaxed to produce an isomerized product, with increased yield of isomerized material and decreased production of light ends.

摘要： A diesel fuel having at least 50% C10 to C20 paraffins, wherein the iso-paraffin to normal paraffin mole ratio is up to 21:1 and higher. This diesel fuel can be produced from a feed containing at least 90% C10+ normal paraffins. This diesel fuel is produced by contacting a feed in an isomerization reaction zone a feed with a catalyst comprising a SAPO-11 and platinum in the presence of hydrogen (hydrogen:feed ratio of from 1,000 to 10,000 SCFB) at a temperature of from 340° C. to 420° C., a pressure of from 100 psig to 600 psig, and a liquid hourly space velocity of from 0.1 hr−1 to 1.0 hr−1.
