| Abstract: | Cross compounding test between waste oils and methanol or ethanol based on H2SO4 was done. The best condition of test is, for methanol: temperature: 70℃; the proportion of methanol and waste oils:1:40, the dosage of catalyst: 7%, the time of reaction: 6h. Influence sequence to outcome of factors is: the proportion of methanol and waste oils>the dosage of catalyst >the time of reaction > temperature. For ethanol: temperature 80℃, the proportion of ethanol and waste oils 1:30, the dosage of catalyst 5%, the time of reaction 6 h. influence to outcome of factors is: the proportion of ethanol and waste oils>temperature>the dosage of catalyst>the time of reaction. |
