Process and apparatus for pyrolysis of hydrocarbons

Claim 2

A PROCESS FOR THE PYROLYSIS OF A HYDROCARBON TO PRODUCE PYROLYSIS PRODUCTS INCLUDING ACETYLENE WHICH PROCESS COMPRISES BURNING HYDROGEN WITH OXYGEN TO FORM A COMBUSTION GAS HAVING A TEMPERATURE IN THE RANGE 4500 TO 5300*F., PASSING SAID COMBUSTION GAS IN A LONGITUDINAL DIRECTION OF FLOW, MAINTAINING A HELICALLY MOVING BLANKET OF TEMPERING GAS ANNULARLY DISPOSED ABOUT THE SAID LONGITUDINALLY FLOWING COMBUSTION GAS IN SUFFICIENT AMOUNT TO COOL SAID COMBUSTION GAS TO A TEMPERATURE NOT HIGHER THAN 4200*F., PREHEATING A GASEOUS HYDROCARBON TO A TEMPERATURE IN THE RANGE 1800 TO 2400*F., INTRODUCING THUS PREHEATED GASEOUS HYDROCARBON INTO ADMIXTURE WITH SAID COMBUSTION GAS IN A GENERALLY TRANSVERSE DIRECTION THERETO, WHEREBY MIXING OF COMBUSTION GAS AND GASEOUS HYDRO-
