Abstract

One or more embodiments relate to a contactor/separator vessel for reacting with fine particles. The contractor/separator vessel includes a spouted bed containing fine Geldart class C particles; and an additional spoutable media to facilitate spouting of the fine Geldart class C particles in order to improve mixing, gas-solid contact/separation.

First claim

What is claimed is:

1 . A contactor/separator vessel for reacting with fine particles, comprising:
a spouted bed containing fine Geldart class C particles; and an additional spoutable media to facilitate spouting of the fine Geldart class C particles in order to improve mixing, gas-solid contact/separation.

2 . The vessel of claim 1 comprising a chemical reactor wherein a temperature varies between about 150° C. and 1000° C.

3 . The vessel of claim 2 wherein the chemical reactor uses a gas distributor and a spout to assist with at least one of fluidization, flow rate and material transport.

4 . The vessel of claim 3 wherein a gas distributed through the gas distributor is pulsed.

5 . The vessel of claim 2 further comprising multiple spouting beds are adjoined.

6 . The vessel of claim 5 wherein the multiple spouting beds are adjoined in a stacked pattern.

7 . The vessel of claim 5 wherein the multiple spouting beds are adjoined in a modular pattern.

8 . The vessel of claim 5 wherein the multiple spouting beds are thermally controlled using heating chambers.

9 . The vessel of claim 5 wherein the multiple spouting beds are thermally controlled using cooling chambers.

10 . The vessel of claim 2 wherein the spouted bed includes an angle of a spout bottom wherein an angle of the spotted bottom ranges from a horizontal to vertical orientation.

11 . The vessel of claim 2 having an internal design and operation promoting mixing and gas-solid contact.

12 . The vessel of claim 1 having one or more pairs of parallel plates or tubes aligned axially in the vessel to stabilize a gas jet to improve spouting stability, facilitate increased solids inventory as well as promoting operation as lower gas velocities.

13 . A chemical reactor for reacting with fine particles, comprising:
a spouted bed containing fine Geldart class C particles; an additional spoutable media to facilitate spouting of the fine Geldart class C particles in order to improve mixing, gas-solid contact; a gas distributor; and a spout where the gas distributor and spout assist with fluidization, flow rate and material transport.

14 . The chemical reactor of claim 13 wherein a temperature varies between about 150° C. and 1000° C.

15 . The chemical reactor of claim 13 wherein a gas distributed through the gas distributor is pulsed.

16 . The chemical reactor claim 13 further comprising multiple adjoined spouting beds.

17 . The chemical reactor of claim 16 wherein the multiple spouting beds are adjoined in a one of a stacked and modular pattern.

18 . The chemical reactor of claim 16 wherein the multiple spouting beds are thermally controlled using at least one of a heating and cooling chambers.

19 . The chemical reactor of claim 13 wherein the spouted bed includes a spouted bottom, where the angle of the spout bottom ranges from a horizontal to vertical orientation.

20 . The chemical reactor of claim 13 having an internal design and operation promoting mixing and gas-solid contact.

21 . The chemical reactor of claim 13 having one or more pairs of parallel plates or tubes aligned axially in the vessel to stabilize a gas jet to improve spouting stability, facilitate increased solids inventory as well as promoting operation as lower gas velocities.
