ABSTRACT:
A reactor of the shell and tube type wherein the head on the first end of the reactor is divided by a partition. A reactant, e.g. oxygen, is passed into one side of the divided head, passed through the tubes containing catalyst on one side of the reactor which are available to that portion of the head. Upon exiting into the head at the opposite end of the reactor the reactant oxygen is mixed with another reactant, e.g. a chlorinated hydrocarbon, and fed into tubes on the other side of the reactor, which also contains catalyst, and wherein the oxidation of the chlorinated hydrocarbon occurs. The product gases exit on the side of the divided head opposite the oxygen inlet at the first end of the reactor. A heat exchange medium surrounds the tubes and circulates within the shell to either heat or cool the said tubes as necessary. When the catalyst employed in the reaction becomes coated with carbonaceous material the flow is reversed and the oxygen fed into that side of the reactor to regenerate the catalyst.
