1. A method of producing a renewable diesel fuel, the method comprising:
providing a co-product derived from a corn mash of a dry-grind ethanol process, the co-product comprising corn distillers dried grains with solubles, corn distillers dried grains, or a combination thereof;
solvent extracting the co-product to produce crude corn oil, the crude corn oil comprising free fatty acids in an amount no more than about 15% by weight of the crude corn oil, crude protein in an amount no more than about 1% by weight of the crude corn oil, nitrogen in an amount no more than about 0.5% by weight of the crude corn oil, and phosphorous in an amount no more than about 50 ppm; and
subjecting the crude corn oil to a conversion process to produce the renewable diesel fuel.
