核桃壳制备活性炭方法及吸附性能的研究
Preparation of Activated Carbon from Walnut Hull and Its Adsorption Capacity
【摘要】 研究了以废弃核桃壳为原料,用磷酸活化法制备粉状活性炭的实验方法及其吸附性能。实验结果表明:废弃核桃壳在氮气保护下,以每分钟升温10℃的速率加热到400℃进行预炭化,再在700℃条件下活化所制备的活性炭具有较强的吸附性能。为林副产品核桃壳的利用提供了一条有价值的途径。
【Abstract】 The activated carbon was produced from walnut hull by H3PO4.and its absorption capacity was investigated.The results showed that the activated carbon,made under the conditions of the protection of nitrogen,heat rate 10℃/min carbonization temperature 400℃,activation time 700℃,possessed high adsorption capacity.It supplied an effective solution to improve the value of forest by-products and solve the environmental pollution.
