Abstract

A method for the vaporization of particulate material includes providing one or more containers each containing possibly distinct particulate materials each having at least one component, fluidizing the particulate material in at least one of the containers, and providing a vaporization zone that is thermally isolated from at least one of the containers. The method further includes delivering particulate material received from each container to the vaporization zone, and applying heat to vaporize the delivered particulate materials at the vaporization zone.

Claims (16)

1. A method for the vaporization of particulate material, comprising:

(a) providing one or more containers each containing possibly distinct particulate materials each having at least one component;

(b) fluidizing the particulate material in at least one of the containers;

(c) providing a vaporization zone that is thermally isolated from at least one of the containers;

(d) delivering particulate material received from each container to the vaporization zone; and

(e) applying heat to vaporize the delivered particulate materials at the vaporization zone.

2. The method according to claim 1 wherein the delivery step is provided by transporting means divided into a first stage and a second stage.

3. The method of claim 2 wherein the first stage transporting means includes an auger mechanism or a translational member.

4. The method of claim 2 wherein the second stage transporting means includes a rotating disk or a translational member.

5. The method according to claim 1 wherein the delivery step is provided by a single stage and includes a rotating disk or translational member.

6. The method according claim 1 further including providing a plurality of cells, each cell receiving a predetermined amount of particulate material.

7. The method according to claim 6 wherein the cells have at least one first size receiving a first predetermined amount of particulate material and at least a second size receiving a second predetermined amount of particulate material.

8. The method according to claim 7 wherein the particulate material in the cell of the first size is delivered from a first container of particulate material and the particulate material in the cell of the second size is delivered from a second container of particulate material, where the particulate material of the first container is different from the particulate material of the second container.

9. The method according to claim 1 further including providing a screen having openings and the openings are sized to capture particulate material.

10. The method according to claim 6 further including removing excess particulate material from the cells and from interstitial areas between cells.

11. The method according to claim 1 wherein the delivery step is provided by a moveable member and further including electrostatically transferring particulate material to the moveable member from the container.
