ABSTRACT:
In a chemisorption reaction process wherein a polar gas is repeatedly alternately adsorbed and desorbed on a complex compound formed by adsorbing said polar gas on a metal salt, said complex compound capable of having a first density if allowed to expand without restriction during said adsorption, a method of increasing the reaction rates of said chemisorption reaction process comprises controlling the volumeric expansion of said complex compound formed during at least the initial adsorption reaction of said polar gas on said metal salt to form at least a partially structurally immobilized, self-supporting, coherent, reaction product mass having a second density. The metal salt may also be mixed with a zeolite, activated carbon, activated alumina or silica gel prior to the first adsorption reaction. In another embodiment, the polar gas is used initially to form a complex compound with the salt and thereafter desorbed and a nonpolar gas used for being adsorbed and desorbed on the zeolite, activated carbon, activated alumina silica gel, or metal hydride.
