原始语种摘要: Abstract Activated carbons were produced from walnut shell by fast activation with H3PO4 in a spouted bed, and the influence of particles fluidization had been investigated. Experimental results showed that walnut shell particles with higher H3PO4 impregnation ratios would be agglomerated in spouted bed, and difficult to fluidize. Therefore, an amount of quartz sands were added to assist fluidization of H3PO4 impregnated walnut shell particles. The BET surface area of activated carbon prepared under fluidization would be obviously increased with H3PO4 impregnation ratio, reaching 1549.6 m2/g for the mass ratio of H3PO4 to walnut shell particles of 2 and activation...
