Method and apparatus for achieving high reaction rates in solid-gas reactor systems
First Claim
1. A reaction apparatus comprising one or more reaction chambers containing a solid reactant adapted to form a reaction product by adsorbing and desorbing a gaseous reactant on said solid reactant said solid reaction product having an increased or decreased volume as compared to said solid reactant prior to said adsorption or desorption reaction, each of said one or more reaction chambers having a reaction chamber volume defined by reaction chamber walls and a reactant support surface, and wherein said reaction chamber walls and/or said reactant support surface are moveable and biased and form movable volumetric expansion control means for maintaining contact with said solid reactant and said reaction product substantially throughout said adsorption and said desorption reactions, whereby said reaction chamber walls and/or said reactant support surfaces provide moveable volumetric expansion control means for restricting the volumetric expansion and optimizing the density of said reaction product, and whereby said reaction chamber walls and said reactant support surface maintain contact with said of reaction product during said adsorption and desorption reactions.

Abstract
Reaction rates in chemisorption reactions involving solid reactants and gaseous ligands are improved by maintaining optimized solid density throughout the reaction. Methods and apparatus which restrict volumetric solid expansion, compression of the solid reactant, and mixture with inert solid porous or particulate materials are disclosed.
