| Abstract: | By using solid acid as catalyst, the waste oil is pretreated for the preparation of biodiesel in tank reactor and fixed-bed reactor. The condition of the pre-esterification of waste oil in tank reactor is 70 ℃ of reaction temperature, reacting for 8 hours and 5% of catalyst dosage. The esterification condition of the waste oil in fixed-bed reactor is 70℃ of reaction temperature, 0.2 h^-1 of the weight hourly space velocity of the oil and 0.2- 0.3 h^-1 of the weight hourly space velocity of the methanol. |
