Abstract

An adsorbent form consisting of a pressed blend of powdered adsorbent and powdered resin. A method of fabricating a pressed adsorbent form consisting of the steps of forming a blend of powdered adsorbent and powdered resin, and compressing said blend to form a self-sustaining form.

Claims (33)

1. A method of fabricating a pressed adsorbent form consisting essentially of the steps of forming a blend of powdered adsorbent and powdered resin, and compressing said blend to form a self-sustaining form, wherein said blend is compressed at a pressure of between about 3,000 pounds per square inch and 50,000 pounds per square inch and said self-sustaining form is subsequently heated to between about 50° C. and 300° C. to activate and soften said resin.

2. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said powdered adsorbent is of a size of between about 10 microns and 5,000 microns, and wherein said powdered resin is of a size of between about 5 microns and 1,000 microns.

3. The method of fabricating a pressed adsorbent form as set forth in claim 2 wherein said powdered adsorbent is present by weight in an amount of between about 10% and 95%.

4. The method of fabricating a pressed adsorbent form as set forth in claim 2 wherein said powdered adsorbent is present by weight in an amount of between about 65% and 90%.

5. The method of fabricating a pressed adsorbent form as set forth in claim 2 wherein said powdered adsorbent is present by weight in an amount of between about 75% and 85%.

6. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said powdered adsorbent is of a size of between about 50 microns and 1,000 microns, and wherein said powdered resin is of a size of between about 10 microns and 500 microns.

7. The method of fabricating a pressed adsorbent form as set forth in claim 6 wherein said powdered adsorbent is present by weight in an amount of between about 10% and 95%.

8. The method of fabricating a pressed adsorbent form as set forth in claim 6 wherein said powdered adsorbent is present by weight in an amount of between about 65% and 90%.

9. The method of fabricating a pressed adsorbent form as set forth in claim 6 wherein said powdered adsorbent is present by weight in an amount of between about 75% and 85%.

10. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said powdered adsorbent is of a size of between about 100 microns and 500 microns, and wherein said powdered resin is of a size of between about 20 microns and 100 microns.

11. The method of fabricating a pressed adsorbent form as set forth in claim 10 wherein said powdered adsorbent is present by weight in an amount of between about 10% and 95%.

12. The method of fabricating a pressed adsorbent form as set forth in claim 10 wherein said powdered adsorbent is present by weight in an amount of between about 65% and 90%.

13. The method of fabricating a pressed adsorbent form as set forth in claim 10 wherein said powdered adsorbent is present by weight in an amount of between about 75% and 85%.

14. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said self-sustaining form is subsequently heated to between about 110° C. and 170° C. to activate said adsorbent and soften said resin.

15. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said self-sustaining form is subsequently heated to between about 130° C. and 150° C. to activate said adsorbent and soften said resin.

16. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said blend is compressed at a pressure of between about 5,000 pounds per square inch and 40,000 pounds per square inch.

17. The method of fabricating a pressed adsorbent form as set forth in claim 16 wherein said self-sustaining form is subsequently heated to between about 110° C. and 170° C. to activate said adsorbent and soften said resin.

18. The method of fabricating a pressed adsorbent form as set forth in claim 16 wherein said self-sustaining form is subsequently heated to between about 130° C. and 150° C. to activate said adsorbent and soften said resin.

19. The method of fabricating a pressed adsorbent form as set forth in claim 1 wherein said blend is compressed at a pressure of between about 9,000 pounds per square inch and 20,000 pounds per square inch.

20. The method of fabricating a pressed adsorbent form as set forth in claim 19 wherein said self-sustaining form is subsequently heated to between about 110° C. and 170° C. to activate said adsorbent and soften said resin.

21. The method of fabricating a pressed adsorbent form as set forth in claim 19 wherein said self-sustaining form is subsequently heated to between about 130° C. and 150° C. to activate said adsorbent and soften said resin.
