摘要
以5种典型的生物质废弃料作为实验材料,进行炭化工艺的研究。总结了生物质炭化材料的制备方法,并对炭粉进行颗粒分布、松装密度、振实密度以及官能团变化的测定和分析。结果表明：随着最终炭化温度的升高,生物质材料的炭化得率降低;5种生物质炭粉颗粒粒径的分布区间为0.11-85μm,主要粒径分布区间为10-20μm;5种生物质炭粉振实密度和松装密度差异较大,同种炭粉的振实密度约为松装密度的2倍;生物质材料炭化后的官能团主要变化为醚键（C—O—C）、羰基（CO）、甲基（—CH3）和亚甲基（—CH2）消失,但仍存有羟基（—OH）、烯烃（CC）和芳香族化合物。
Five typical waste biomass materials were used for the research on technology of the carbonization, The preparation methods of biomass charcoal materials were summarized. The particle distribution, loose density, tap density and functional groups of charcoal powder were determined. The result shows that the yield of the carbonization decreases when the temperature rises; the distribution of particles of the five biomass materials is between 0. 11-85 μm, and mainly between 10-20 μm; there are big differences between loose density and tap density of the five biomass charcoal powders, and for the same one the ratio of tap density to loose density is about 2 ; the change of functional groups of the five biomass materials after the carbonization is that the ether（C-O-C） , earhonyl（C=O） , methyl（-CH3 ） and methylene（-CH2 ） groups disappear, hut the hydroxyl（-OH） , alkene （C=C） and aromatic compounds still exist.
