Abstract
A process for making a mechanically strong, high permeance, and relatively inexpensive support structure for zeolite membranes is described. In an example implementation, a process includes forming a silica powder from silica fibers, mixing the silica powder and a polymer solution to form a mixture, forming the mixture into a shaped mixture, and sintering the shaped mixture to form a silica support.
