Abstract

In this study,the activation technology was studied for Chinese prickly ash kernel,by phosphoric acid activation method.Through the single-factor and the L₉(3⁴) orthogonal tests,the optimal technological conditions were obtained as follows:concentration of phosphoric acid solution 75 % (V/V),solid-liquid ratio 1:1 g·mL^-1,activating temperature 600 ℃ and activating time 25 min,Main technological factors were listed as follows in descending order:activating time,activating temperature,concentration of phosphoric acid solution,solid-liquid ratio.With the optimal technology above,the average caramel decolorization rate was 108%,the yield of the activated carbon was up to 44%.The research results could provide an effective way for the utilization of Chinese prickly ash seeds Meanwhile,it could provide technical guidance and ideas for active carbon production and raw material selection.
