摘要
利用SEM、N2-物理吸附和联碱滴定法等表征手段系统比较了竹质活性炭和普通竹炭与其他材质活性炭在物化性能方面的异同,同时利用CO-化学吸附考察了这些材料作为催化剂载体对负载钯催化剂金属钯分散度的影响。实验结果表明,竹质活性炭在比表面积、孔结构、灰分含量和表面基团等物化性能方面都已具备作为催化剂载体的条件,显示出成为新催化剂载体的潜力。
The physicochemical properties of activated carbon derived from bamboo were compared with activated carbon of other origin via characterization with SEM, N2-adsorption and Boehm method. Effects of the material as catalyst support on dispersity of palladium were investigated using CO-chemisorption. The results showed that the bamboo-derived activated carbon was qualified as catalyst support in BET surface area, pore structure, ash content and surface groups.
