ABSTRACT:
A reactor with swing feeds is provided for oxychlorination. This reactor comprises multiple inlets with controls capable of introducing feed streams sequentially to the reactor. In one configuration, a feed stream comprises a paraffin or olefin hydrocarbon such as methane or ethylene, and a second feed stream comprises oxygen and hydrogen chloride. By segregating these feeds, combustion reactions can be minimized and yields of chlorinated components increased.
