Carbon black manufacture

Claim 1

A PROCESS FOR THE MANUFACTURE OF CARBON BLACK WHICH INCLUDES THE STEPS: (1) PREHEATING A CARBON BLACK PRODUCING FEEDSTOCK CONSISTING ESSENTIALLY OF AN ADMIXTURE OF FROM ABOUT 75 TO 25 PARTS OF A RESIDUAL OIL HAVING A HYDROGEN TO CARBON ATOMIC RATIO OF LESS THAN ABOUT 1.25 AND A * API GRAVITY LESS THAN ABOUT 10, SAID RESIDUAL OIL FURTHER CHARACTERIZED IN CONTAINING A SUBSTANTIAL AMOUNT OF A NON-VAPORIZABLE COMPONENT, AND CORRESPONDINGLY FROM ABOUT 25 TO 75 PARTS JOF A PETROLEUM DISTILLATE HAVING A HYDROGEN TO CARBON ATOMIC RATIO OF GREATER THAN ABOUT 1.25 AND A * API GRAVITY BETWEEN ABOUT 10 AND 30 TO A TEMPERATURE WHICH EFFECTS SUBSTANTIALLY COMPLETE VAPORIZATION OF SAID PETROLEUM DISTILLATE COMPONENT THEREOF; (2) CONTINUOUSLY INTRODUCING INTO ONE END OF AN ELONGATED REACTOR SAID PREHEATED FEEDSTOCK AND CONTINUOUSLY ESTABLISHING ABOUT THE LATTER A TURBULENT HEAT-RADIANT LAYER OF HOT COMBUSTION GASES HAVING A TEMPERATURE IN EXCESS OF ABOUT 2000*F.; (3) CONTINUOUSLY PASSING SAID FEEDSTOCK TOGETHER WITH THE SURROUNDING LAYER OF HOT COMBUSTION GASES THROUGH THE ELONGATED REACTOR SO AS TO EFFECT DISSOCIATION OF A PREDOMINANT PORTION OF THE FEEDSTOCK INTO CARBON BLACK AND BY-PRODUCT GASES; AND (4) RECOVERING CARBON BLACK FROM THE EFFLUENT EMANATING FROM SAID REACTOR.
