A method for reducing the vinyl chloride content of vinyl chloride hold strength gasstroemen

摘要

Vinyl chloride is incinerated at relatively mild temperatures, e.g., 20 DEG to 300 DEG 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 DEG -300 DEG 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.
