Abstract
A process for the catalytic conversion of various chlorinated hydrocarbon byproducts and waste products especially to less chlorinated, useful or salable products, in which a chlorinated hydrocarbon feedstock containing two or more chlorines is reacted with hydrogen in the presence of a catalyst consisting essentially of an active hydrogenating metal component such as platinum in elemental or compound form, and a surface segregating metal component such as copper in elemental or compound form on a support.
Claims27
A process for the conversion of a chlorinated alkane feedstock containing two or more chlorines to reaction products comprising a less chlorinated alkene, wherein the chlorinated alkane feedstock is reacted with hydrogen in the presence of a supported catalyst consisting essentially of an active hydrogenating metal component selected from the Group VIb and Group VIII metals in elemental or compound form and a surface segregating metal component selected from the metals of Groups IB, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIA, VIIA and VIII in elemental or compound form on a support, the group VIII hydrogenating metal component being different from the group VIII metal comprising the surface segregating metal component under conditions effective to produce the corresponding less chlorinated alkene in a yield of at least about 10 percent and in preference to a corresponding less-chlorinated alkane.
