| 摘 要： | 对4种生物柴油促进原油污染砂粒释放油的效果进行了研究,并探讨了菜籽生物柴油投加量和砂粒粒径对促进效果的影响。结果表明,菜籽生物柴油的促进效果最好,8 h释放量达到73%,废油脂生物柴油的效果最差,仅为52%;生物柴油的促进效果随着投加量的增大而升高,当投加量超过海水体积的5%时促进效果不再明显增加;在生物柴油作用下,小粒径砂粒上原油的释放效果优于大粒径砂粒。

| Abstract: | This study tested the promotive effects of four kinds of biodiesel by different origins to release oil from crude oil contaminated sand and analyzed the influence of biodiesel dosage and sand diameter on releasing effects.The results indicate that the promotive effect of rapeseed biodiesel,which helped to release 73% crude oil from contaminated sand,is the best.In contrast,as the worst,the waste fat biodiesel only removed 52%.The promotive effect increased with the dosage of biodiesel,and when the dosage was more than 5%(V/V),it was no longer significant.Smaller diameter sand is tested to be a benefit factor for improving the promotive effect of biodiesel. |
