木质素基生物炭制备及对亚甲基蓝的吸附性能
Preparation of Lignin-Based Biochar and Adsorption Capability of Methylene Blue
摘要
Abstract
In order to study the effect of temperature on the yield and adsorption performance of biochar, the Lignin-Based biochar at different temperatures were prepared by slow pyrolysis method. Biomass pyrolysis yield, carbon yield, volatiles, ash and methylene blue adsorption values of biochar were measured. The results of experiments showed that the pyrolysis yield and carbon yield decreased first and then increased, the volatile components first rose and then decreased with the carbonization temperature from 300℃ to 700℃. At 500℃,the yield of pyrolysis and carbon were 54. 09% and 50. 77% , respectively. Meanwhile, the ash content and the volatile content was 3. 32% and 45. 91% ,respectively. The adsorption experiments showed that the maximum adsorption of methylene blue by lignin-based biochar was 37. 31 mg/g at 300℃. The C—H and C=O bonds had broken during the pyrolysis.关键词
