摘要
[Objective] The aim was to study on the high-valued utilization of China Fir sawdust extracted essential oil.[Method] In the field of fir essential oil extraction,the processed China fir sawdust was used to prepare low-valued products.The high-valued utilization of China fir sawdust extracted essential oil(CFSEEO),namely as a precursor to prepare granular activated carbons(GACs),was attempted.The materials were characterized by ultimate analysis,SEM and XRD.[Rusult] A butane working capacity(BWC)of 14.3 g/100 ml was obtained by using the GACs with apparent density of 0.25 g/ml.It was available to introduce the technology of extracting essential oil from the China fir sawdust(CFS)in the industrial production process of activated carbons with high BWC(12.0-16.5 g/100 ml)and high surface area(2 000-2 630 m2/g)using phosphoric acid based on previous studies of the authors.[Conclusion] The resulting carbon prepared with the raw materials containing lower moisture exhibited a better property on n-butane adsorption.
