Abstract

Active component -SO3H of activated carbon loaded catalyst is prepared by carbide sulfonation reaction between concentrated sulfuric acid and glycerol. And effects of different reaction conditions were studied on the basis of the reduce ratio of acid value after the esterification reaction occurred in fixed bed reactor. The experimental data show that the optimal catalyst preparation conditions are: mass ratio of glcerin and concentrated sulfuric acid on carbide sulfonation reaction is 1:2, activated carbon fully filled and less affected by the preparation temperature condition. The optimal reaction conditions are: molar ratio between gutter oil and methanol on esterification reaction is 1:12.5, reacting continuously by 5 hours and under the condition of reaction temperature of 65°C. Under these conditions, the esterification ratecould reach as high as 96.0%.
