text: A process for producing an off-gas which contains a substantial amount of acetylene from an in-gas containing suitable stock hydrocarbon which can be pyrolyzed to produced acetylene which comprises firing in the same direction substantially adjacent first and second regenerative heating zones, the second heating Zone being fired to an acetylene-forming temperature and a temperature higher than the temperature of the first Zone, passing the in-gas into the first zone at a point in the rst zone substantially opposite from the point of firing of the first Zone, conducting the in-gas through the rst zone and out of the first zone substantially at the point of ring, motivating the gas emerging from the first Zone and conducting this motivated gas into the second hotter Zone, the motivated gas being conducted into the second zone at substantially the point of ring of the second Zone whereby the movtivated gas is quickly cracked at the higher temperature to the off -gas aforementioned containing substantial amounts of acetylene, stopping the flow of gas through said zones before the temperature of the second Zone has fallen below that at which the effective pyrolysis of the gas to acetylene ceases and thereafter repeating the cycle.
