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

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.

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.

Process for making molecular sieves

The use of a polyalphaolefin oil or combinations of polyalphaolefin oils to modify the softening point characteristics of a tackifier and compositions containing a tackifier and polyalphaolefin oil are disclosed herein.
