Latest Patents

One of Yu-Han Chu's latest patents involves carbon molecular sieve membranes containing a group 13 metal and a method to manufacture them. This carbon molecular sieve (CMS) membrane is designed to have improved separation characteristics, specifically for separating olefins from their corresponding paraffins. The membrane is composed of carbon with minimal trace amounts of sulfur and incorporates a group 13 metal. The manufacturing process involves pyrolyzing a precursor polymer that is devoid of sulfur, into which the group 13 metal has been incorporated in a reduced state. This pyrolysis occurs in a nonoxidizing atmosphere, ensuring that the metal remains in a reduced state, either covalently bonded to carbon or nitrogen or in its metallic form.
