The distiller's grains in a liquor factory are selected as the main material to study the preparation of activated carbon with KOH activation. The solid-to-liquid ratio A, KOH concentration B, activation temperature C, activation time D are regarded as variables to produce single factor experiment. The results show that the best preparation conditions of various factors are: 50% KOH concentration, solid-liquid ratio of 1:4, activation temperature of 750°, activation time of 2.0h. The L9 (34) orthogonal experiment is carried out by selecting three levels from each single factor, showing that the importance order of the factors is: B > A > C > D. In addition, when KOH solution concentration is 60%, the solid-liquid ratio is 1:5, activation temperature is 700°, and activation time is 2.0h, the performance of the preparation of activated carbon is the best.
