Abstract

A method of and apparatus for increasing yields of certain recoverable gases, particularly ethylene feedstocks, produced during the manufacture of coke from a raw material in a coking apparatus is disclosed. The method includes the steps of heating the raw material to its coking temperature to cause evolvement of the recoverable gases in an effluent zone in the coking apparatus above the raw material; and simultaneously introducing a cooling fluid into the effluent zone to maintain the temperature of the recoverable gases in the effluent zone below their decomposition temperature, thereby increasing the yield of certain recoverable gases from the coking apparatus while maintaining maximum coke-producing rates in the coking apparatus.
