磷酸法制竹屑活性炭的生产性实验

PRODUCTION TEST OF ACTIVATED CARBON FROM BAMBOO SAWDUST WITH H_3PO_4

以竹屑代替木屑为原料,利用现有连续内热式活化炉及配套设备,用磷酸法生产竹屑活性炭,其热能消耗、每吨活性炭磷酸消耗、磷酸循环使用等基本与木屑炭相当,但对乳酸等实物溶液的脱色效果优于以木屑为原料的市售活性炭。

Using continuous internal heating kiln and mating equipment,activated carbon was produced by activation with H_3PO_4 from bamboo sawdust instead of wood sawdust. The product showed better decoloration of solution, such as lactic acid, than commercial one from wood sawdust.
