Patent number: 5056591Abstract: A method is provided of conducting a thermochemical absorption or desorption reaction between a gas and a solid in the presence of a heat-carrying fluid in a closed enclosure. This method comprises a first step in which, for the pressure prevailing in the reactor, the variation of the mean power of the reaction is determined as a function of the difference which exists between the temperature of the heat-carrying fluid and the equilibrium temperature of the reaction, given by the Clapeyron diagram, for defining an optimum zone in which the reaction takes place with maximum mean power, and a second step in which the reaction takes place, in which a reference temperature is imposed on the heat-carrying fluid such that the reaction takes place in the optimum zone.Type: GrantFiled: September 2, 1988Date of Patent: October 15, 1991Assignee: Societe Nationale Elf AquitaineInventors: Bernard Spinner, Sylvain Mauran, Alain Roca, Marianne Balat
