Study on Optimization of Activated Carbon Preparation Process Based on Apricot shell

摘要

Activated carbon is a kind of material with many pores and large specific surface. Activated carbon has been widely applied in many fields for its excellent adsorption and steady chemical characters. Activated carbon was prepared with apricot shell as raw materials by the sequence of crushing, screening, carbonization and activation. To improve adsorption ability of activated carbon, KOH was added as a activator into the carbonization materials. The effect of carbonization and activation conditions on benzene value and Vitamin B_(12) value were investigated. Benzene value and Vitamin B12 value of activated carbon were improved from 163.01mg·g~(-1) and 19.16mg·g~(-1) to 589.14mg·g~(-1) and 35.02mg·g~(-1), respectively.
