Abstract
Vinyl chloride is incinerated at relatively mild temperatures, e.g., 20.degree. to 300.degree.C., by contacting it in a combustion zone with an oxygen-containing gas in the presence of hydrated metal oxide catalyst selected from the group consisting of the oxides of manganese, copper, and mixtures of said oxides. The temperature of incineration is adjusted within the range of 20.degree.-300.degree.C. depending on the relative humidity of the gases in the combustion zone to maintain catalytic activity. Commonly, the vinyl chloride is contained in a gas stream in small amounts, e.g., less than 0.05 weight percent.
