text: A process for producing an off-gas containing substantial amounts of acetylene from feed stock consisting essentially of normally gaseous hydrocarbons by the application of a plurality of regenerative heating steps in a first and second regenerative heating zones containing slots which comprises: passing said gaseous hydrocarbons upwardly through slots in a first regenerative heating zone the top of which Zone is at a temperature substantially higher than the bottom thereof and of a temperature sufficient to convert at least a part of said gaseous hydrocarbons into a second gas containing intermediate hydrocarbon products more readily convertible to acetylene, however, the temperature of this first zone not materially exceeding 2000o injecting va motive gas into this second gas, said injecting being in a manner that the motive gas draws the second gas toward the top of the second regenerative heating zone and mixes with this second gas to form a third gas, passing this third gas at a high velocity downwardly through slots in this second regenerative heating Zone, said zone being shorter and hotter than the rst zone aforesaid whereby the third gas is heated for less than le of a second at 'a temperature sufficient to cause substantial acetylene formation but not in excess of 3000c F.; and quickly cooling the acetylene containing gas produced to a temperature at which acetylene is reasonably stable.
