【摘要】 以糠醛渣为原料,配以一定比例的粘合剂制备出球形活性炭(SAC-F)。比较了SAC-F与活性炭纤维(ACF)和粒状活性炭(GAC-C)的流体力学性能,初步探讨了直径为4~5mm SAC-F的制备参数,考察了它的碘吸附值和对模拟烟气中SO2的脱除性能,以及物理和表面化学性质。结果表明,在相同的装填高度下,随着空速的增加,SAC-F上压降增加得最慢,ACF的增加速率是它的6~7倍,GAC-C是它的1~2倍;虽然SAC-F比GAC-C的比表面积和孔容都小,但其平均脱硫率为87%,明显优于GAC-C,与GAC-C相比,SAC-F表面含有较少的C-O。更多还原

【Abstract】 In this paper,spherical activated carbon（SAC-F） from furfural residue were prepared,and phenolic resin was used as adhesive.The hydromechanical properties of SAC-F was compared with activated carbon fiber（ACF） and granular activated carbon（GAC-C）.The preparation parameter,adsorptive capacity of I₂ and properties of flue gas desulfurization of SAC-F whose diameter was 4～5mm were studied.In addition,the physical and chemical characters of SAC-F were also analyzed.The results show that at the same loading height,when space velocity enhance,the increased velocity of pressure decrease on the SAC-F was slowest among three kind of carbon materials.This velocity of ACF and GAC-C was 6～7 and 3～4 times respectively as much as SAC-F.Although,the specific surface area and pore volume of SCF-F were smaller than GAC-F,its average desulfurization efficiency was 87% and better than GAC-C remarkably.It could be ascribed to that there were smaller C-O on the surface of SAC-F in comparison with GAC-C.更多还原
