Abstract:
1. A conversion process, comprising: introducing a gaseous reactant-rich stream at a feed temperature into a heat exchange passage of a heat exchanging reaction zone to pre-heat the reactant-rich stream to an inlet temperature, wherein the heat exchange passage comprises a shell-side of a shell-and-tube heat exchanging reactor; introducing the pre-heated reactant-rich stream at the inlet temperature into a reaction passage to exothermically convert the reactant gas to a product gas to form a product-enriched mixture of the reactant and product gases, wherein the reaction passage comprises a tube-side of the shell-and-tube heat exchanging reactor, and wherein the tube side comprises a plurality of catalyst-containing tubes; indirectly transferring heat from the reaction passage to the heat exchange passage at a rate effective to maintain the mixture of gases below the equilibrium temperature; and recovering an effluent from an outlet from the reaction passage at a discharge temperature enriched in the product gas.
