Process for production of acetylene and other products by partial combustion of hydrocarbons

Claim 1

A PROCESS FOR MAKING ACETYLENE COMPRISING SUBJECTING A HYDROCARBON TO INCOMPLETE COMBUSTION WITH OXYGEN, COOLING THE HOT REACTION GASES CONTAINING ACETYLENE TO MINIMIZE DISSOCIATION OF THE ACETYLENE, SAID COOLING BEING CARRIED OUT BY CONTACTING A HYDROCARBON OIL WITH THE SAID HOT GASES, THE LATTER BEING AT A TEMPERATURE AT LEAST SUFFICIENTLY HIGH TO RESULT IN PARTIAL CRACKING OF SAID OIL, THE HYDROCARBON BEING A MINERAL OIL HAVING A BOILING POINT ABOVE 250*C., THE QUANTITY OF OIL BEING INITIALLY ADJUSTED TO LOWER THE TEMPERATURE OF THE GASES DOWN TO WITHIN THE RANGE OF 700* TO 800*C., AN ADDITIONAL QUANTITY OF SAID OIL BEING INTRODUCED INTO THE EXIT GASES SO PRODUCED TOO LOWER THE TEMPERATURE DOWN TO A TEMPERATURE NOT HIGHER THAN ABOUT 200*C., THE TIME INTERVAL BETWEEN THE FIRST AND SECOND COOLING STAGES BEING NOT MORE THAN A FEW HUNDREDTHS OF A SECOND.
