利用扁桃壳制备糠醛和活性炭的研究

Research on Producing Furfural and Activated Charcoal from Almond Seed Shells

以扁桃壳为原料,用硫酸法制取糠醛,工艺条件为:每50g扁桃壳加入2.0mol/L硫酸250.0ml,蒸馏温度160℃,蒸馏时间2.0h。用糠醛渣试制了活性炭,产品活性炭的次甲基蓝吸附力达到了分析纯标准。

The technology of producing furfural and activated charcoal from almond seed shells was studied by adding 2.0mol/L sulfuric acid 250.0ml per 50g shells and maintaining the temperature at 160℃ in 2.0h. The activated charcoal was produced from the residue of furfural, and the absorbability of activated charcoal reached analytically pure standard.
