  • Dewaxing using a molecular sieve catalyst
    Patent number: 11542446
    Abstract: 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.
    Type: Grant
    Filed: August 14, 2019
    Date of Patent: January 3, 2023
    Assignee: Exxon Mobil Technology and Engineering Company

  • Molecular sieves and a process for making molecular sieves
    Patent number: 11318451
    Abstract: 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.

  • Process for making molecular sieves
    Patent number: 11111153
    Abstract: 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.
