| Abstract: |
| Using thermogravimetric analysis method, the effect of di-tertiary-butyl peroxide(DTBP) on pyrolysis characteristics of biodiesel from swill-cooked dirty oil was studied.Selecting nitrogen and oxygen as reaction gases, weight loss curve and differential thermogravimetric curve of biodiesel sample were drawn when the temperature rised from 50℃ to 400℃ with 20℃/min of heating rate, and the volatile and combustion characteristics were analyzed in the pyrolysis process of biodiesel samples with different dosages of DTBP. The results showed that the addition of DTBP had little effect on the volatile characteristics of biodiesel; the combustion index of the biodiesel added with DTBP increased； DTBP could effectively promote the combustion of fuel and made biodiesel better flammability. |
