Regenerative treatment manner of the catalytic converter, and the organicity halogen compound in the resolution mannered null suffering treatment

摘要

PROBLEM TO BE SOLVED: To provide a regeneration treatment method of a catalyst capable of restoring the activity of the poisoned catalyst used in the decomposition treatment of oil in which a very small amount of an organohalogen compound gets mixed, and a decomposition method of the organohalogen compound using the regenerated catalyst.;SOLUTION: The catalyst lowered in its decomposition capacity, which is used in the decomposition treatment of the organohalogen compound in oil to be treated in the presence of an alkaline substance, a hydrogen donor and the catalyst, is washed with a washing agent to remove the neutral salt of dissociated halogen and the alkaline substance bonded to the catalyst to restore the decomposition capacity of the catalyst. This regenerated catalyst is used to again decompose the organohalogen compound in the oil. By this constitution, since the decomposition treatment due to the catalyst and the regeneration treatment can be performed at the same time using two systems of catalyst columns 2 filled with the catalyst, continuous decomposition treatment can be continued even in a case decomposition does not advance without disassembling an apparatus.;COPYRIGHT: (C)2006,JPO&NCIPI
