Title: Chemical reactor for use with overly reactive chemicals

Patent ·
OSTI ID:1483652

A chemical reactor for use in a chemical process wherein a reactant and/or a target product is prone to produce undesirable byproducts through secondary reactions. The reactor is configured with a first flow passage for passing a flow of an overly reactive reactant; a permeable first wall for controlled flow of the overly reactive reactant into a second flow passage providing a flow of a second reactant; a permeable second wall having a catalyst supported on an inner surface thereof for catalyzing reaction of the reactants flowing in the second flow passage; the permeable second wall passing through a flow containing the target product; and a non-permeable third wall defining a third flow passage for exiting the product mixture. The reactor can be employed in selective oxidation, oxidative dehydrogenation, and alkylation processes to reduce the formation of byproducts.
