Abstract:

The efficient ways for preparing low-cost and industry-standard 180# bunker oil using coal tar light oil, coal diesel and asphalt were investigated. The effect of depressants EVA, T602, and BEM on the reduction of solidification point of the blended marine fuel oil was tested. The results show that no significantly reduction in solidification point of the blending fuel oil is found by additing depressants. The C9 and C10 components can be used as depressants for their low solidification point and high aromaticity. When adding 10.7% of C9, the pour point of blended marine fuel oil drops to 15 ℃, which ensures the flow of marine fuel oil at normal temperature. The investigations of spot test and microscopic photos indicate that the addition of C9 can enhance the stability and compatibility of the blending marine fuel oil.
