Hollow fibers with a thin zeolite beta-polysulfone mixed matrix selective layer and enhanced selectivity for He/N 2 and O 2 /N 2 separation have been developed in this study. It is believed that the heat treatment and the coating processes combine to bring out the separation properties of zeolite be
