Abstract: A chemical reactor system includes: a feed; a methane oxychlorination catalyst, wherein a product of an oxychlorination reaction is dichloromethane; and a dichloromethane conversion catalyst, wherein the dichloromethane conversion catalyst provides a product stream having a dichloromethane selectivity less than 5%. The addition of the dichloromethane conversion catalyst to the reactor bed can decrease the amount of dichloromethane produced and increase the amount of monochloromethane produced. Accordingly, dichloromethane does not have to be separated from the product stream and the monochloromethane can then be used to produce other products, such as olefins.
