APPARATUS AND METHOD FOR PREPARATION OF COMPOUNDS OR INTERMEDIATES THEREOF FROM A SOLID MATERIAL, AND USING SUCH COMPOUNDS AND INTERMEDIATES

摘要

An apparatus is described, as including a reaction region for contacting a reactant gas with a reactive solid under conditions effective to form an intermediate product, and an opening for allowing an unreacted portion of the gaseous reagent and the intermediate product to exit the reaction region. The apparatus can be beneficially employed to form a final product as a reaction product of the intermediate product and the reactant gas. The reaction of the reactant gas and reactive solid can be conducted in a first reaction zone, with the reaction of the reactant gas and intermediate product conducted in a second reaction zone. In a specific implementation, the reaction of the reactant gas and intermediate product is reversible, and the reactant gas and intermediate product are flowed to the second reaction zone at a controlled rate or in a controlled manner, to suppress back reaction forming the reactive solid.

1. An apparatus comprising:
a reaction chamber for contacting a gaseous reagent with a solid material under temperature and pressure conditions effective to form an intermediate species; a plurality of openings along a surface of the reaction chamber for allowing an unreacted portion of the gaseous reagent and the intermediate species to exit the reaction chamber; and a reduced temperature region configured to receive the unreacted portion of the gaseous reagent and the intermediate species exiting the reaction chamber and effect reaction between the intermediate species and the unreacted portion of the gaseous reagent to form an end product.
