Treatment of carbonaceous solids

Claim 1

THE METHOD OF CARBONIZING A BITUMINUOUS MATERIAL OF HIGH VOLATILITY AND LOW ASH CONTENT WHICH COMPRISES FEEDING SAID MATERIAL IN SUBDIVIDED FORM TO A DENSE TURBULENT FLUIDIZED BED OF CARBONACEOUS SOLIDS MAINTAINED IN A CARBONIZATION ZONE, PASSING A GAS UPWARDLY THROUGH SAID BED AT CARBONIZATION TEMPERATURES OF ABOUT 800*-1600* F. AND ELEVATED PRESSURES OF ABOUT 5-100 P. S. I. G. CONDUCTIVE TO THE CRACKING CONVERSION OF CARBONIZATION PRODUCTS OF UNIDESIRABLY HIGH BOILING POINT INTO GASES, LIGHT OILS AND COKE, WITHDRAWING VOLATILE CARBONZATION PRODUCTS CONTAINING ENTRAINED CARBONACEOUS SOLIDS FINES UPWARDLY FROM SAID ZONE, SCRUBBING SAID VOLATILE PRODUCTS IN A SCRUBBING ZONE AT A TEMPERATURE ABOVE THE BOILING POINT OF THE HIGHEST BOILING VOLATILE CARBONIZATION PRODUCTS DESIRED FOR RECOVERY WITH A HYDROCARBONACEOUS LIQUID COMPRISING SUBSTANTIAL PROPORTIONS OF CONDENSED CARBONIZATION PRODUCTS BOILING ABOVE ABOUT 700* F. TO REMOVE ENTRAINED SOLIDS FINES FROM SAID VOLATILE PRODUCTS, RECOVERING VOLATILE PRODU CTS FREE OF ENTRAINED SOLIDS FROM SAID SCRUBBING ZONE, AND RECYCLING USED SCRUBBING LIQUID CONTAINING SAID ENTRAINED SOLIDS IN SUSPENSION TO SAID CARBONIZATION ZONE WHEREBY SAID SCRUBBED FINES ARE IMPREGNATED BY SAID SCRUBBING LIQUID AND AGGLOMERATED IN THE COURSE OF SAID RECYCLE PROCEDURE TO FORM PARTICLES OF SUBSTANTIALLY GREATER SIZE THAN THAT OF SAID ENTRAINED FINES RECYCLED SCRUBBING LIQUID BEING CRACKED TO FORM LIGHTER PRODUCTS IN SAID CARBONIZATION ZONE.

Claim 2

THE METHOD OF CARBONIZING A BITUMINUOUS MATERIAL OF HIGH VOLATILITY AND LOW ASH CONTENT WHICH COMPRISES FEEDING SAID MATERIAL IN SUBDIVIDED FORM TO A DENSE TURBULENT FLUIDIZED BED OF CARBONACEOUS SOLIDS MAINTAINED IN A CARBONIZATION ZONE, PASSING A GAS UPWARDLY THROUGH SAID BED AT CARBONIZATION TEMPERATURES OF ABOUT 800*-1600* F. AND ELEVATED PRESSURES OF ABOUT 5-100 P. S. I. G. CONDUCTIVE TO THE CRACKING CONVERSION OF CARBONIZATION PRODUCTS OF UNIDESIRABLY HIGH BOILING POINT INTO GASES, LIGHT OILS AND COKE, WITHDRAWING VOLATILE CARBONZATION PRODUCTS CONTAINING ENTRAINED CARBONACEOUS SOLIDS FINES UPWARDLY FROM SAID ZONE, SCRUBBING SAID VOLATILE PRODUCTS IN A SCRUBBING ZONE AT A TEMPERATURE ABOVE THE BOILING POINT OF THE HIGHEST BOILING VOLATILE CARBONIZATION PRODUCTS DESIRED FOR RECOVERY WITH A HYDROCARBONACEOUS LIQUID COMPRISING SUBSTANTIAL PROPORTIONS OF CONDENSED CARBONIZATION PRODUCTS BOILING ABOVE ABOUT 700* F. TO REMOVE ENTRAINED SOLIDS FINES FROM SAID VOLATILE PRODUCTS, RECOVERING VOLATILE PRODU CTS FREE OF ENTRAINED SOLIDS FROM SAID SCRUBBING ZONE, AND RECYCLING USED SCRUBBING LIQUID CONTAINING SAID ENTRAINED SOLIDS IN SUSPENSION TO SAID CARBONIZATION ZONE WHEREBY SAID SCRUBBED FINES ARE IMPREGNATED BY SAID SCRUBBING LIQUID AND AGGLOMERATED IN THE COURSE OF SAID RECYCLE PROCEDURE TO FORM PARTICLES OF SUBSTANTIALLY GREATER SIZE THAN THAT OF SAID ENTRAINED FINES RECYCLED SCRUBBING LIQUID BEING CRACKED TO FORM LIGHTER PRODUCTS IN SAID CARBONIZATION ZONE.
