Latest Patents

One of Rolston's latest patents is a method of manufacturing renewable diesel from biological feedstock. This method involves introducing a primary feedstock comprising biologically-derived triglycerides with catalyst poisons into a first reaction chamber. The process includes hydrolyzing the primary feedstock within the first reaction and liquid-liquid extraction chamber for at least an hour. This results in the separation of reacted triglycerides into an aqueous solution containing glycerol and catalyst poisons, as well as an intermediate feedstock comprising free fatty acids and catalyst poisons. The method further includes distilling the intermediate feedstock to separate it into a purified intermediate stream and a lower volume bottom stream containing unreacted triglyceride, diglyceride, monoglyceride, free fatty acids, and catalyst poisons. Additionally, the purified intermediate feedstock is combined with a hydrogen stream and converted in a second reaction chamber with a metallic catalyst bed into a product comprising long-chain alkanes. Finally, the method includes hydrotreating the purified intermediate feedstock into a renewable diesel product.
