  • Method of making SAPO-34 membranes for use in gas separations
    Patent number: 8568518
    Abstract: A method of making a crystalline silicoaluminophosphate-34 (SAPO-34) membrane. The method comprises the steps of providing a porous support having a pore size distribution such that a small proportion of its pores are larger than 10 microns, seeding the porous support with SAPO-34 seed crystals by capillary suspension infiltration to give a seeded support, and growing a SAPO-34 membrane layer on the surface of the seeded support.
    Type: Grant
    Filed: March 3, 2011
    Date of Patent: October 29, 2013
    Assignee: Shell Oil Company
    Inventors: Benedictus Clemens Bonekamp, Hendrik Jan Marsman, Johannis Pieter Overbeek, Paul Jason Williams

  • Process of producing a microporous hydrophobic inorganic membrane
    Patent number: 6797206
    Abstract: Microporous hydrophobic inorganic membrane having an average pore size of less than 2 nm and a hydrophobicity index octane/water of at least 2 can be obtained by a process comprising hydrolyzing a metal alkoxide in the presence of a hydrocarbyl metal alkoxide having at least one non-hydrolyzable group in an organic solvent to produce a metal (hydr)oxide sol, and precipitating metal (hydr)oxide from said sol and drying the precipitate. In this process, at least 50% of the amount of hydrocarbyl metal alkoxide is introduced into the solvent after 20% of the hydrolysis period has lapsed.
