Claims
- 1. A method for carrying out gas/solid reactions for the activation and reactivation of activated carbon, comprising:
- conveying carbonaceous material to a first zone and directly contacting said carbonaceous material in said first zone with gas sufficient to subject said carbonaceous material to drying,
- thereafter conveying said carbonaceous material to a second zone which is a horiztonally vibrating fluidized bed maintained at a temperature of 600.degree. to 950.degree. C. by combustion gas which is at a temperature of 950.degree. to 1200.degree. C. and depositing said carbonaceous material onto said vibrating horizontal bed,
- directly contacting said carbonaceous material in said bed with an activating gas, said activating gas being introduced into said bed from beneath said bed, said activating gas comprising steam, at a temperature of 600.degree. to 900.degree. C., passing the activating gas up through said carbonaceous material to thereby fluidize said bed while said material is being vibrated in a horizontal manner to thereby approximate plug flow of said material, the composition of said combustion gas and said activating gas being different,
- there being cross flow of the fluidizing gases to ensure high water vapor partial pressure in the bed of carbonaceous material and rapid removal of inhibiting product gases.
