Abstract
A systems and method for manufacturing a base stock from an ethanol stream are described herein. An example method includes dehydrating an ethanol stream to form an impure ethylene mixture, recovering an ethylene stream from the impure ethylene mixture, and oligomerizing the ethylene stream to form a raw oligomer stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream, and the hydro-processed stream is distilled to form the base stock.
