Hydrocarbon conversion process and apparatus

Claim 1

THE METHOD FOR CONVERTING A PROCESS STREAM WHICH COMPRISES PASSING AT LEAST A PORTION OF SAID PROCESS STEAM HORIZONTALLY AND RADIALLY THROUGH A BED OF SOLID PARTICLES MAINTAINED IN A FILTRATION ZONE, PASSING SAID PROCESS STREAM DOWNWARDLY INTO A REACTION ZONE INTO CONTACT WITH A CONVERSION CATALYST AT CONVERSION CONDITIONS, WITHDRAWING THE EFFLUENT FROM SAID REACTION ZONE, DISCONTINUING THE FLOW OF REACTANT STREAM WIHEN SAID CONVERSION CATALYST HAS BECOME DEACTIVATED, PASSING AN OXYGEN-CONTAINING GAS UPWARDLY THROUGH SAID CONVERSION ZONE, INTRODUCING QUENCH FLUID BETWEEN SAID REACTION ZONE AND SAID FILTERING ZONE THROUGH A DISTRIBUTING MEANS IN AN AMOUNT SUFFICIENT TO MAINTAIN THE REGENERATION OFF-GAS AT A TEMPERATURE NOT SUBSTANTIALLY HIGHER THAN THE OPERATING TEMPERATURE OF SAID FILTRATION ZONE AND WITHDRAWING A MIXED STREAM OF QUENCH FLUID AND REGENERATION OFFGAS FROM THE UPPER PORTION OF SAID FILTRATION ZONE.

Claim 2

THE METHOD FOR CONVERTING A PROCESS STREAM WHICH COMPRISES PASSING AT LEAST A PORTION OF SAID PROCESS STEAM HORIZONTALLY AND RADIALLY THROUGH A BED OF SOLID PARTICLES MAINTAINED IN A FILTRATION ZONE, PASSING SAID PROCESS STREAM DOWNWARDLY INTO A REACTION ZONE INTO CONTACT WITH A CONVERSION CATALYST AT CONVERSION CONDITIONS, WITHDRAWING THE EFFLUENT FROM SAID REACTION ZONE, DISCONTINUING THE FLOW OF REACTANT STREAM WIHEN SAID CONVERSION CATALYST HAS BECOME DEACTIVATED, PASSING AN OXYGEN-CONTAINING GAS UPWARDLY THROUGH SAID CONVERSION ZONE, INTRODUCING QUENCH FLUID BETWEEN SAID REACTION ZONE AND SAID FILTERING ZONE THROUGH A DISTRIBUTING MEANS IN AN AMOUNT SUFFICIENT TO MAINTAIN THE REGENERATION OFF-GAS AT A TEMPERATURE NOT SUBSTANTIALLY HIGHER THAN THE OPERATING TEMPERATURE OF SAID FILTRATION ZONE AND WITHDRAWING A MIXED STREAM OF QUENCH FLUID AND REGENERATION OFFGAS FROM THE UPPER PORTION OF SAID FILTRATION ZONE.

Claim 3

AN APPARATUS FOR EFFECTING A CATALYTIC CONVERSION WHICH COMPRISES IN COMBINATION A VERTICAL HOUSING DIVIDED INTO AN UPPER FILTERING SECTION AND A LOWER REACTION SECTION, FLUID INTRODUCING AND DISTRIBUTING MEANS DISPOSED BETWEEN SAID SECTIONS, SAID REACTION SECTION CONTAINING A CATALYST BED BETWEEN UPPER AND LOWER PERFORATE PLATES, SAID FILERING SECTION CONTAINING AN ANNULARLY SHAPED BED OF SOLID PARTICLES BETWEEN CONCENTRIC CYLINDRICAL PERFORATE MEMBERS DISPOSED AXIALLY TO SAID HOUSING AND FLUID INTRODUCING AND WITHDRAWING CONDUIT MEANS CONNECTED TO THE UPPER AND LOWER HOUSING CLOSURES.

Claim 4

AN APPARATUS FOR EFFECTING A CATALYTIC CONVERSION WHICH COMPRISES IN COMBINATION A VERTICAL HOUSING DIVIDED INTO AN UPPER FILTERING SECTION AND A LOWER REACTION SECTION, FLUID INTRODUCING AND DISTRIBUTING MEANS DISPOSED BETWEEN SAID SECTIONS, SAID REACTION SECTION CONTAINING A CATALYST BED BETWEEN UPPER AND LOWER PERFORATE PLATES, SAID FILERING SECTION CONTAINING AN ANNULARLY SHAPED BED OF SOLID PARTICLES BETWEEN CONCENTRIC CYLINDRICAL PERFORATE MEMBERS DISPOSED AXIALLY TO SAID HOUSING AND FLUID INTRODUCING AND WITHDRAWING CONDUIT MEANS CONNECTED TO THE UPPER AND LOWER HOUSING CLOSURES.
