Claim 1
Independent Claim
156 words
IN A HYDROCARBON OIL FLUID COKING PROCESS, A METHOD OF INTRODUCING HEAT-CARRYING PARTICULATE CONTACT SOLIDS DIRECTLY INTO THE DENSE TURBULENT REACTION BED WHICH COMPRISES UPWARDLY PASSING A RELATIVELY DILUTE SOLIDS-GAS SUSPENSION OF HOT CONTACT SOLIDS THROUGH A PASSGEWAY INCLINED 10* TO 60* FROM THE VERTICAL AND TERMINATING IN A HORIZONTAL PLANE, SAID SOLID-GAS SUSPOENSION BEING DISCHARGED FROM SAID PASSAGEWAY DIRECTLY INTO SAID BED, INITALLY DLOWING SAID SOLIDS-GAS SUPENSION THROUGH SAID PASSAGEWAY AT A VELOCITY IN THE RANGE OF 5 TO 20 FT/SEC. AND AT A DENSITY IN THE RANGE OF 10 TO 25% OF THE TRUE PARTICLE DENSITY OF SAID CONTACT SOLIDS, THEREAFTER INCREASING THE VELOCITY OF SAID SUSPENSION TO A VELOCITY INTHE RANGE OF 10 TO 40FT/SEC., DISCHARGING SAID SUSPENSION AT THE INCREASED VELOCITY FROM THE TERMINAL, HORIZONTAL PLANE OF SAID PASSAGEWAY DIRECTLY INTO SAID REACTION BED, THE AREA IMMEDIATELY ABOVE SAID HORIZONTAL PLANE BEING PARTIALLY ENCLOSED TO PREVENT BACKFLOW OF SOLIDS INTO SAID PASSAGEWAY.
