Abstract
Abstract A reactor that consists of a single shell that contains a reaction zone and a regeneration zone. The reaction zone and regeneration zone are arranged in such a manner that (a) a particulate solid may be transferred by flow of gases from the regeneration zone to the reaction zone by a first route and then back to the regeneration zone by a second route; and (b) the gases passing through the regeneration zone are not transferred to the reaction zone and the gases passing through the reaction zone are not transferred to the regeneration zone.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
383 words
A reactor for effecting separate and successive contact of a particulate solid with a first gas stream and a second gas stream without substantial mixing of said gas streams comprising: an enclosed shell having a top, a bottom and side surfaces therebetween, said enclosed shell having a predetermined horizontal cross section, a first wall inside said shell attached to said top and extending downward into said shell thereby defining a first contact zone between the side surfaces of said shell and said first wall and a second contact zone inside said first wall, said second contact zone being separated from said first contact zone at said top, a second wall intermediate the side surfaces of said shell and said first wall thereby dividing said first contact zone into inner and outer first contact zones, a third wall inside said first wall thereby dividing said second contact zone into inner and outer second contact zones, said second and third walls being joined to one another below the bottom of said first wall so as to provide a first clearance between the bottom of said first wall and the junction of said second and third walls and a second clearance between said junction and the bottom of said shell, said second clearance defining an essentially horizontal flow path for particulate solid between said outer first contact zone and said inner second contact zone, first supply means for supplying said first gas stream to said inner first contact zone for effecting fluidization of particulate solid therein and transfer of particulate solid from said inner first contact zone to said outer first contact zone, second supply means for supplying said second gas stream to said inner second contact zone for effecting fluidization of particulate solid therein and transfer of particulate solid from said inner second contact zone to said outer second contact zones, said second supply means being arranged in said second clearance to inject said second gas stream in a generally horizontal direction therein so as to transfer particulate solid from said outer first contact zone through said second clearance and into said inner second contact zone, first gas removal means for removing said first gas from said first contact zone, and second gas removal means for removing said second gas from said second contact zone.
Claim 2
Dependent Claim
383 words
A reactor for effecting separate and successive contact of a particulate solid with a first gas stream and a second gas stream without substantial mixing of said gas streams comprising: an enclosed shell having a top, a bottom and side surfaces therebetween, said enclosed shell having a predetermined horizontal cross section, a first wall inside said shell attached to said top and extending downward into said shell thereby defining a first contact zone between the side surfaces of said shell and said first wall and a second contact zone inside said first wall, said second contact zone being separated from said first contact zone at said top, a second wall intermediate the side surfaces of said shell and said first wall thereby dividing said first contact zone into inner and outer first contact zones, a third wall inside said first wall thereby dividing said second contact zone into inner and outer second contact zones, said second and third walls being joined to one another below the bottom of said first wall so as to provide a first clearance between the bottom of said first wall and the junction of said second and third walls and a second clearance between said junction and the bottom of said shell, said second clearance defining an essentially horizontal flow path for particulate solid between said outer first contact zone and said inner second contact zone, first supply means for supplying said first gas stream to said inner first contact zone for effecting fluidization of particulate solid therein and transfer of particulate solid from said inner first contact zone to said outer first contact zone, second supply means for supplying said second gas stream to said inner second contact zone for effecting fluidization of particulate solid therein and transfer of particulate solid from said inner second contact zone to said outer second contact zones, said second supply means being arranged in said second clearance to inject said second gas stream in a generally horizontal direction therein so as to transfer particulate solid from said outer first contact zone through said second clearance and into said inner second contact zone, first gas removal means for removing said first gas from said first contact zone, and second gas removal means for removing said second gas from said second contact zone.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 further comprising first aerator means for supplying air to said second clearance.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein the heights of said second and third walls are essentially equal.
Claim 5
Dependent Claim
21 words
The apparatus of claim 1 wherein said second supply means is located at the bottom of said inner second contact zone.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1 wherein said first supply means is located at the bottom of the said inner first contact zone.
Claim 7
Dependent Claim
24 words
Apparatus according to claim 1 wherein said first and second gas removal means each comprise means for separating a particulate solid from a gas.
Claim 8
Dependent Claim
16 words
The apparatus of claim 6 wherein said first and second gas removal means each comprise cyclones.
Claim 9
Dependent Claim
17 words
The apparatus of claim 6 wherein the heights of said second and third walls are essentially equal.
Claim 10
Dependent Claim
27 words
The apparatus of claim 6 wherein the side walls of said shell, said first wall, said second wall and said third wall are generally vertical and parallel.
Claim 11
Dependent Claim
25 words
The apparatus of claim 9 wherein the horizontal cross sections of said shell, said first wall, said second wall and said third wall are similar.
Claim 12
Dependent Claim
25 words
The apparatus of claim 10 wherein the horizontal cross sections of said shell, said first wall, said second wall and said third wall are circles.
