Recuperation in solid-vapor sorption system using sorption energy and vapor mass flow

摘要

A method of carrying out recuperation between alternately absorbing and desorbing reactors in which in a first reaction cycle in a desorbing reactor a gaseous reactant is desorbed from a solid sorbent and concurrently in an absorbing-reactor the gaseous reactant is absorbed on a solid sorbent, and in a second reaction cycle, absorption and desorption are reversed in said reactors, respectively, comprising communicating the reaction chambers of the desorbing reactor with the reaction chamber of the absorbing reactor and directing a portion of gaseous reactant desorbed from the sorbent composition in the desorbing reactor near the completion of a desorbing cycle to the absorbing reactor for less than about 10 minutes prior to reversing the cycles.
