A method for isomerizing alpha olefins to produce an isomerization mixture comprising branched olefins can comprise contacting an olefinic feed including one or more C-Calpha olefins with a catalyst under skeletal isomerization conditions, wherein the catalyst comprises a molecular sieve having an MRE topology; and obtaining an isomerization mixture comprising one or more C-Cbranched olefins.

Methods for isomerizing alpha olefins

Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.

Dewaxing using a molecular sieve catalyst

Compositions can include mixtures having from about 2 wt % to about 40 wt % of C-Clinear paraffins based on the weight of the mixture, from about 60 wt % to about 98 wt % of C-Cbranched saturated hydrocarbons based on the weight of the mixture, and less than or equal to about 30 wt % of Csaturated hydrocarbons based on the weight of the mixture. Methods to obtain these compositions can include the isomerization of one or more C-Calpha olefins under skeletal isomerization conditions to obtain an isomerization mixture and the hydrotreating of the isomerization mixture.

Branched paraffinic compositions derived from isomerized and hydrogenated linear alpha olefins

Processes are provided for preparing molecular sieves. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier L selected from the group consisting of nonionic surfactants, anionic surfactants, sugars and combinations thereof.

Molecular sieves and a process for making molecular sieves

Processes are provided for preparing molecular sieves of framework structure MEI, TON, MRE, MWW, MFS, MOR, FAU, EMT, or MSE. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier L selected from the group consisting of cationic surfactants having a quaternary ammonium group comprising at least one hydrocarbyl group having at least 12 carbon atoms, nonionic surfactants, anionic surfactants, sugars and combinations thereof.

The disclosure relates to olefin oligomerization processes and related zeolites and structure directing agents. The olefin oligomerization processes can exhibit relatively high conversions. The zeolites can exhibit comparatively high stabilities. The zeolites can have relatively high ratios of external surface area to total surface area. An exemplary zeolite is a beta zeolite having a relatively high ratio of external surface area to total surface area. The disclosure also relates to structure directing agents, and methods of using the structure direction agents to prepare the zeolites.

Olefin oligomerization processes and related zeolites and structure directing agents

Processes are provided for preparing molecular sieves for use as catalysts. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier which may be selected from cationic surfactants having a single quaternary ammonium group comprising at least one hydrocarbyl group having at least 12 carbon atoms, nonionic surfactants, anionic surfactants, sugars, and combinations thereof.
