摘要
以磷酸为活化剂,用山楂核研制粒状活性炭,就工艺条件对产品收率和A法焦糖脱色率的影响进行了研究,最佳工艺条件为预润湿时间6h,固液比1∶0.8,磷酸浓度65%,活化温度450℃,活化时间50min,所得产品的A法焦糖脱色率达100%以上,收率也高达35%。
The granular active carbon is produced with hawthorn kernel using phosphoric acid as active agent.The effects of technology conditions on the quality and yield of product are discussed.The preference technology conditions are as follow:prewetting time 6 h,solid/liquid ratio 1∶0.8,65% phosphoric acid,activating temperature 450 ℃,and activating time 50 min.The yield of the prouduct was 35%,and the caramel decolorizing yield of the product reached to more than 100%.
