棉秆用磷酸法制取脱色粉状活性炭的初步研究

Using Phosphoric Acid Method to Make Decoloured Carbon Dust From Cotton Stalks

我国是产棉大国，大多棉秆没有得到进一步的开发利用．本实验以棉秆为原料，用磷酸法从棉秆中制取脱色活性炭，并对炭化、活化等工艺条件进行了研究，实验结果表明，产品的收率及脱色性能较稳定，且活化剂的消耗量较少，为把棉秆转变为活性炭，提供了比较理想的实验条件．

this paper introduces the method of using the activizing of phosphoric acid method to make activated carbon dust from cotton stalks.It is a research on the technological conditions of carbonizing and activizing etc..Results show that the yield and the decoloured quality are steble.The products made in this way are of high quality.
