Abstract

Low temperature behavior of renewable diesel and blends with petroleum diesel

Use of renewable diesel (a.k.a. hydrogenated vegetable oil, HVO) is growing worldwide. While it’s tempting to think of renewable diesel as a drop-in replacement for petroleum diesel, we have determined that extra consideration is required for the use of renewable diesel in cold climates. Our primary modes of investigation have been to measure the cloud point, cold filter plugging point (CFPP), and pour point of blends of renewable diesel and petroleum diesel. Further, we have investigated the role of cold flow improvers and pour point depressants in lowering the CFPP and pour point. We found that additives continue to provide benefits. Lastly, we have evaluated the behavior of renewable diesel using a cold stage microscope. These experiments clearly show a difference in the wax crystallization behavior of renewable diesel versus petroleum diesel.
