Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
117 words
Integral apparatus for fluidized bed reaction systems comprising: a reactor having a disentrainment zone near one end thereof, a compression-diffuser zone near the other end thereof and a fluidized bed reaction zone therebetween; suction recycle fluid conduit means fixedly supported within said reactor extending along the entire length through an interior portion of said fluidized bed and provided for the inlet flow of recycle fluid at one end thereof positioned in said disentrainment zone and discharge flow of recycle fluid at the other end thereof positioned in said compression-diffuser zone; and cooler and gas distributor means positioned in said reactor near the lower end thereof, said cooler means being in thermal contact with said discharge recycle fluid.
Claim 2
Dependent Claim
117 words
Integral apparatus for fluidized bed reaction systems comprising: a reactor having a disentrainment zone near one end thereof, a compression-diffuser zone near the other end thereof and a fluidized bed reaction zone therebetween; suction recycle fluid conduit means fixedly supported within said reactor extending along the entire length through an interior portion of said fluidized bed and provided for the inlet flow of recycle fluid at one end thereof positioned in said disentrainment zone and discharge flow of recycle fluid at the other end thereof positioned in said compression-diffuser zone; and cooler and gas distributor means positioned in said reactor near the lower end thereof, said cooler means being in thermal contact with said discharge recycle fluid.
Claim 3
Dependent Claim
23 words
Apparatus in accordance with claim 1, wherein said cooler means also serves as gas distributor means and acts to support said fluidized bed.
Claim 4
Dependent Claim
22 words
Apparatus in accordance with claim 1, wherein said disentrainment zone has a diameter exceeding that of the other zones of said reactor.
Claim 5
Dependent Claim
26 words

Claim 6
Dependent Claim
35 words
Apparatus in accordance with claim 1, wherein the passages of said gas distributor means are provided with stand-off, protective means positioned thereover to prevent the back-flow of solid particular material from said fluidized bed therethrough.
Claim 7
Dependent Claim
137 words
Apparatus for fluidized bed reaction systems comprising: a reactor having a disentrainment zone near one end thereof, a compression-diffuser zone near the other end thereof and a fluidized bed reaction zone therebetween; suction recycle fluid conduit means fixedly supported within said reactor extending along the entire length through an interior portion of said fluidized bed and provided for the inlet flow of recycle fluid at one end thereof positioned in said disentrainment zone and discharge flow of recycle fluid at the other end thereof positioned in said compression-diffuser zone; single, integral cooler and gas distributor means positioned in said reactor near the lower end thereof, said cooler means being in thermal contact with said suction recycle fluid conduit means; and compressor means positioned in said reactor at said other end of said suction recycle fluid conduit means.
Claim 8
Dependent Claim
137 words
Apparatus for fluidized bed reaction systems comprising: a reactor having a disentrainment zone near one end thereof, a compression-diffuser zone near the other end thereof and a fluidized bed reaction zone therebetween; suction recycle fluid conduit means fixedly supported within said reactor extending along the entire length through an interior portion of said fluidized bed and provided for the inlet flow of recycle fluid at one end thereof positioned in said disentrainment zone and discharge flow of recycle fluid at the other end thereof positioned in said compression-diffuser zone; single, integral cooler and gas distributor means positioned in said reactor near the lower end thereof, said cooler means being in thermal contact with said suction recycle fluid conduit means; and compressor means positioned in said reactor at said other end of said suction recycle fluid conduit means.
