Claim 1
Independent Claim
234 words
A METHOD OF CONTACTING LIQUID REACTANT AT LEAST A PORTION OF WHICH IS NON-VOLATILE AT CONTACTOR TEMPERATURE AND PRESSURE WITH REACTANT GAS IN THE PRESENCE OF PARTICLEFROM SOLID CONTACT MATERIAL WHICH COMPRISES INTRODUCING LIQUID REACTANT AT AN ELEVATED TEMPERATURE AN PRESSURE INTO A REACTION ZONE HAVING CONFINED THEEIN AT LEAST ONE CONFINED SATURATION ZONE AND APLURALITY OF AT LEAST TWO SUPERPOSED, SEPARATED, ANNULAR PRIMARY STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MATERIAL CONCENTRIC WITH SAID CONFINED SATURATION ZONE, PASSING SAID HEATED LIQUID REACTANT DOWNWARDLY THROUGH AT LEAST ONE OF SID STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MATRIAL, GATHERING THE LIQUID REACTANT IN A POOL IN SAID REACTION ZONE BELOW THE LOWER MOST STATIC BED OF PARTICLE-FORM SOLID CONTACT MATERIAL, IN A STREAM OF REACTANT GAS LIFTING A PORTION OF LIQUID REACTANT FROM THE AFORESAID POOL TO THE TOP OF THE UPPER MOST STATIC BED OF PARTICLE-FORM SOLID CONTACT MATERIAL AS A CONFINED STREAM COMPRISING LIQUID REACTANT AND REACTANT GAS TO PHYSICALLY DISSOLVE AN AMOUNT OF REACTANT GAS IN SAID LIFTED PORTION OF LIQUID REACTANT TO MAINTAIN IN SAID LIFTED PORTION AN AMOUNT OF REACTANT GAS AT LEAST EQUAL TO THE AMOUNT OF REACTANT GAS CONSUMED PER UNIT VOLUME OF TOTAL LIQUID REACTANT FLOWING THROUGH SAID PLURALITY OF SUPERPOSED SEPARATED ANNULAR PRIMARY STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MASS MATERIAL, SEPARATING REACTANT GAS AND MATERIALS VOLATILE AT REACTION ZONE PRESSURE AND TEMPERATURE FROM LIQUID REACTANT PHYSICALLY
Claim 2
Independent Claim
234 words
A METHOD OF CONTACTING LIQUID REACTANT AT LEAST A PORTION OF WHICH IS NON-VOLATILE AT CONTACTOR TEMPERATURE AND PRESSURE WITH REACTANT GAS IN THE PRESENCE OF PARTICLEFROM SOLID CONTACT MATERIAL WHICH COMPRISES INTRODUCING LIQUID REACTANT AT AN ELEVATED TEMPERATURE AN PRESSURE INTO A REACTION ZONE HAVING CONFINED THEEIN AT LEAST ONE CONFINED SATURATION ZONE AND APLURALITY OF AT LEAST TWO SUPERPOSED, SEPARATED, ANNULAR PRIMARY STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MATERIAL CONCENTRIC WITH SAID CONFINED SATURATION ZONE, PASSING SAID HEATED LIQUID REACTANT DOWNWARDLY THROUGH AT LEAST ONE OF SID STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MATRIAL, GATHERING THE LIQUID REACTANT IN A POOL IN SAID REACTION ZONE BELOW THE LOWER MOST STATIC BED OF PARTICLE-FORM SOLID CONTACT MATERIAL, IN A STREAM OF REACTANT GAS LIFTING A PORTION OF LIQUID REACTANT FROM THE AFORESAID POOL TO THE TOP OF THE UPPER MOST STATIC BED OF PARTICLE-FORM SOLID CONTACT MATERIAL AS A CONFINED STREAM COMPRISING LIQUID REACTANT AND REACTANT GAS TO PHYSICALLY DISSOLVE AN AMOUNT OF REACTANT GAS IN SAID LIFTED PORTION OF LIQUID REACTANT TO MAINTAIN IN SAID LIFTED PORTION AN AMOUNT OF REACTANT GAS AT LEAST EQUAL TO THE AMOUNT OF REACTANT GAS CONSUMED PER UNIT VOLUME OF TOTAL LIQUID REACTANT FLOWING THROUGH SAID PLURALITY OF SUPERPOSED SEPARATED ANNULAR PRIMARY STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MASS MATERIAL, SEPARATING REACTANT GAS AND MATERIALS VOLATILE AT REACTION ZONE PRESSURE AND TEMPERATURE FROM LIQUID REACTANT PHYSICALLY
Claim 3
Dependent Claim
126 words
THE METHOD OF CONTACTING LIQUID REACTANT AT LEAST A PORTION OF WHICH IS NON-VOLATILE AT CONTACTOR TEMPERATURE AND PRESSURE AS SET FORTH AND DESCRIBED IN CLAIM 1 WHEREIN THE SAID REACTION ZONE CONFINES TWO SEPARATE STATIC BEDS OF PARTICLE-FORM SOLID CONTACT MATERIAL, WHEREIN ONE OF SAID SUPERPOSED, SEPARATED, ANNULAR, PRIMARY STATIC PRIMARY BEDS OF PARTICLE-FORM SOLID CONTACT MATERIAL COMPRISES "RUGGED" (AS DEFINED HEREINBEFORE) HYDROCRACKING CATALYST, WHEREIN THE OTHER OF SAID STATIC PRIMARY BEDS OF PARTICLE-FORM SOLID CONTACT MATERIAL COMPRISES "SELECTIVE" (AS DEFINED HEREINBEFORE) HYDROCRACKING CATALYST, WHEREIN THE LIQUID REACTANT IS A MIXTURE OF HYDROCARBONS HAVING AN INITIAL BOILING POINT OF AT LEAST 650*F., WHEREIN THE REACTANT GAS IS HYDROGEN, AND WHEREIN SAID MIXTURE OF HYDROCARBONS CONTACTS SAID "RUGGED" HYDROCRACKING CATALYST BEFORE CONTACTING SAID "SELECTIVE" HYDROCRACKING CATALYST.
