REACTORS AND METHODS FOR PROCESSES INVOLVING PARTIAL OXIDATION REACTIONS
First Claim
1. A reactor suitable for conducting a partial oxidative reaction, wherein the reactor comprises a vessel comprising a process channel and a composite catalyst structure,wherein the composite catalyst structure comprises a catalyst layer, comprising a substrate and a catalyst, andwherein at least a portion of the composite catalyst structure has a porous heat transfer structure configured to quench free radicals and prevent explosions or propagation of a fire during the partial oxidative reaction.

Abstract
Described herein are improved chemical reactors for carrying out partial oxidation reactions. The chemical reactor permits the use of levels of oxygen above the lower explosion limit (LEL) typically used in partial oxidation reactions, which increases both volumetric reactivity and conversion per pass, resulting in reduced separation and reactant recycle costs. Also described are methods of using the reactors.
