Claim 1
Independent Claim
200 words
THE METHOD OF PROCESSING A LIQUID HYDROCARBON CHARGE CONTAINING COMPONENTS BOILING ABOVE THE RANGE OF GASOLINE, WHICH COMPRISES HEATING SUCH A CHARGE BY CONTACTING THE SAME IN LIQUID STATE AND IN CONTROLLED QUANTITY WITH HOT GRANULAR ADSORPTIVE CONTACT MATERIAL, SAID GRANULAR MATERIAL BEING AT A TEMPERTURE HIGHER THAN SAID CHARGE AND DIRECTLY TRANSFERRING HEAT CONTAINED THEREIN TO SAID CHARGE EFFECTING AT LEAST PARTIAL VAPORIZATION OF SAID CHARGE, THE CONTACTING OF THE CHARGE WITH SAID GRANULAR MATERIAL BEING EFFECTED BY ADMITTING THE LIQUID CHARGE PERIPHERALLY INTO A LATERALLY CONFINED UPWARDLY MOVING STREAM OF SAID GRANULAR MATERIAL IMPELLED BY AN UPWARDLY FLOWING GASIFORM MEDIUM COMPATIBLE WITH HYCARBONS, LIMITING THE QUANTITY OF LIQUID HYDROCARBONS THUS CONTACTED WITH THE GRANULAR MATERIAL TO AN AMOUNT SUCH THAT ANY OF SUCH HYDROCARBONS NOT VAPORIZED THEREBY ARE ADSORBED IN THE GRANULAR MATERIAL DURING UPWARD TRAVEL OF THE GRANULAR MATERIAL, DISCHARGING SAID GRANULAR MATERIAL FROM THE IMPELLING INFLUENCE OF SAID GASIFORM MEDIUM TO TERMINATE UPWARD MOVEMENT OF SAID GRANULAR MATERIAL, THEREAFTER PASSING SIAD GRANULAR MATERIAL, AS A COMPACT GRAVITATING BED THROUGH A LATERALLY CONFINED HYDROCARBON PROCESSING ZONE, AND CONTACTING SAID BED OF GRANULAR MATERIAL WITH HYDROCARBON VAPORS TO BE PROCESSED AND INCLUDING VAPORS FORMED FROM SAID LIQUID CHARGE.
