摘要： An improved hydroisomerization catalyst system and process for making a base oil product using a combined catalyst system comprising SSZ-91 molecular sieve and SSZ-95 molecular sieve. The catalyst system and process generally involves the use of a catalyst comprising an SSZ-91 molecular sieve and a separate catalyst comprising an SSZ-95 molecular sieve to produce dewaxed base oil products by sequentially contacting the catalysts with a hydrocarbon feedstock. The catalyst system and process provide improved base oil yield along with other beneficial base oil properties.

摘要： Systems and methods are provided for processing a feed derived from a biomass source that contains nitrogen in the form of fatty amides, e.g., derived from hydrothermal processing of a biomass source feed, while reducing/minimizing the amount of heteroatom removal performed during subsequent/concurrent hydroprocessing. Optionally, the feed can also contain free fatty acids. This is accomplished in part by first exposing the feed to a catalyst comprising a rare earth oxide, alkali oxide, and/or alkaline earth oxide, which can remove the nitrogen heteroatoms from the compounds within the feed or can convert the nitrogen to a form readily removed in subsequent hydroprocessing. The catalyst may also suitable for catalyzing coupling (such as condensation) or conversion reactions of amides, carboxylic acids, carboxylic acid derivatives, and/or other molecules in the feed suitable for participating in the coupling reaction.

摘要： A new crystalline molecular sieve designated SSZ-95 is disclosed. In general, SSZ-95 is synthesized from a reaction mixture suitable for synthesizing MTT-type molecular sieves and maintaining the mixture under crystallization conditions sufficient to form product. The product molecular sieve is subjected to a pre-calcination step, and ion-exchange to remove extra-framework cations, and a post-calcination step. The molecular sieve has a MTT-type framework and a H-D exchangeable acid site density of 0 to 50% relative to molecular sieve SSZ-32.

摘要： A method for modification of pretreated acidic porous material via selective cation exchange using suitable solvent to obtain higher noble metal dispersion is described herein. The solvent system required for cation exchange should have its dielectric constant in the range of 25-45, wherein this solvent property is found to impart significant effect on cation loading and distribution, which in turn defines the stability, dispersion of the noble metals. The catalyst so obtained has higher noble metal dispersion and when used for hydroisomerization reaction, leads to higher selectivity even at significantly high conversion values.
摘要翻译： 本文描述了通过使用合适的溶剂通过选择性阳离子交换改性预处理的酸性多孔材料以获得更高贵金属分散体的方法。 阳离子交换所需的溶剂系统的介电常数应在25-45的范围内，其中发现这种溶剂性质对阳离子负载和分布具有显着的影响，从而限定了贵金属的稳定性，分散性。 如此获得的催化剂具有更高的贵金属分散体，并且当用于加氢异构化反应时，即使在显着高的转化率下也导致更高的选择性。
