摘要:
采用多功能低温测定仪和旋转粘度计测定了生物柴油/矿物柴油混合燃料的冷滤点、凝点和粘度，研究了混合燃料的低温流动性能及流变学性能。结果表明：0#柴油调入生物柴油后，混合柴油的冷滤点降低，粘温性提高，低温流动性改善；不同温度下，剪切速率对混合燃料表观粘度影响不同。当温度高于冷滤点时，剪切速率对混合燃料表观粘度影响较小；当温度低于冷滤点时，剪切速率增大，混合燃料表观粘度降低，且随温度降低，表观粘度随剪切速率增大而降低更为明显。
Abstract:
With the growing problem of global energy shortages and environment deterioration，the protection of the natural environment of mankind’s survival becomes an urgent solution.As a high quality biological liquid fuel，biodiesel has been favored all over the world.In this paper，low temperature performance and rheological properties of biodiesel/petrodiesel blends were studied to find influencing factors and rules of low temperature characteristics of biodiesel and to find ways of improving its cold flow properties.Cold filter plugging point，solidification point and viscosity of biodiesel diesel blends were measured by a multifunctional low temperature instrument.The low temperature fluidity and rheological property of the biodiesel diesel blends were tested on a rotatory viscometer.The results indicate that blending of biodiesel with petrodiesel considerably improved the viscosity－temperature performance and low temperature fluidity.The influence of shear rate on apparent viscosity of the blended fuels varied with temperatures.Under the temperatures higher than the cold filter plugging point，the influence of shear rate on apparent viscosity was not obvious.Under the temperatures lower than the cold filter plugging point，the apparent viscosity of the blended fuels decreased remarkably with increasing shear rate，especially at lower temperatures.
