Process for clarifying biofuels
View Patent ↗Haze may be removed from a biofuel or biofuel intermediate by using a clarifier. The clarifier includes copolymer prepared using a formulation comprising an alpha olefin and maleic anhydride. The clarifier may also be used with admixtures of biofuels, biofuel intermediates, or biofuel feedstocks with conventional hydrocarbons.
1. A process for removing haze from a biofuel or biofuel intermediate comprising admixing the biofuel or biofuel intermediate with a clarifier comprising a copolymer at a concentration ranging from about 3 ppm to about 10,000 ppm per volume to clarify the biofuel or biofuel intermediate, the copolymer being prepared using a formulation comprising an alpha olefin and maleic anhydride.
2. The process of claim 1 wherein the copolymer is further reacted with an amine or an alcohol.
3. The process of claim 1 further comprising centrifuging an admixture of a biofuel or biofuel intermediate and a clarifier.
4. The process of claim 1 wherein the biofuel or biofuel intermediate is admixed with a conventional hydrocarbon.
5. The process of claim 4 wherein the biofuel or biofuel intermediate is a biodiesel.
