Abstract
A self-supporting structure comprising an inorganic sorbent and method for preparing is described in which the self-supporting structure is substantially free of sorbent fines and the sorption characteristics of the sorbent particles is retained. The process for immobilizing the sorbent particles in the self-supporting structure comprises the steps of: PA0 (a) preheating inorganic sorbent particles to an elevated temperature; PA0 (b) mixing the sorbent particles with particles of a polymeric binding material to form a mixture comprising the particles of polymeric binding material adhered to the sorbent particles; and PA0 (c) heating the mixture to about the solid-liquid transition temperature of the polymeric binding material with or without pressure to form a structure which upon cooling is self supporting.
