Refining catalyst laden hydrocarbons

Claim 1

THE REFINING OF THE PRODUCTS OF A CONTACT PROCESS FOR THE CONVERSION OF HYDROCARBONS WHEREIN A GASIFORM HYDROCARBON MATERIAL IS CONTACTED WITH A MASS OF FINELY DIVIDED SOLIDS IN A REACTION ZONE AND THE REACTION PRODUCTS THUS PRODUCED ARE SEPARATED SUBSTANTIALLY FROM SAID MASS OF SOLIDS AND THEREAFTER CONTAIN A SMALL AMOUNT OF ENTRAINED SOLID FINES RELATIVE TO THE QUANTITY OF SOLIDS PRESENT IN THE REACTION ZONE, THE IMPROVEMENT WHICH COMPRISES COOLING THE HOT GASIFORM REACTION PRODUCT AND ENTRAINED SOLID FINES TO CONDENSE A MAJOR PORTION OF HIGH BOILING NORMALLY LIQUID PRODUCTS, SCRUBBING THE SOLID FINES OUT OF UNCONDENSED GASIFORM PRODUCTS TO FORM A SLURRY, SETTLING SAID SLURRY, DECANTING A SUBSTANTIALLY SOLIDS-FREE PORTION OF THE HIGH BOILING CONDENSATE FROM THE SETTLED SLURRY, COOLING THE UNCONDENSED GASIFORM PRODUCTS SUFFICIENTLY TO CONDENSE A MAJOR PORTION OF RELATIVELY LOWER BOILING NORMALLY LIQUID PRODUCTS THEREFROM THUS LEAVING UNCONDESED NORMALLY GASEOUS PRODUCTS, STRIPPING LOWER BOILING NORMALLY LIQUID PRODUCTS FROM THE DECANTED HIGH BOILING CONDENSATE BY REDUCING THE PRESSURE AND BY CONTACTING THE SAME WITH A PORTION OF NORMALLY GASEOUS PRODUCTS WHEREBY THE LATTER PRODUCTS ARE ENRICHED, AND CONTACTING THE ENRICHED NORMALLY GASEOUS PRODUCTS AND ANOTHER PORTION OF THE NORMALLY GASEOUS PRODUCTS WITH THE LIQUID HYDROCARBON FEED MATERIAL FOR THE CONVERSION PROCESS TO ABSORB THEREFROM RELATIVELY LOWER BOILING NORMALLY LIQUID PRODUCTS BY ABSORPTION.
