Pretreatment of fats and oils in the production of biofuels

a technology of biofuels and fats, applied in the direction of biofuels, fatty-oils/fat refining, fuels, etc., can solve the problems of shortening the useful life of feedstocks, reducing the ability to catalytically convert them into hydrocarbons, and so as to reduce the activity of hydroprocessing and shorten the useful life , the effect of increasing the overall cost of biofuel production

Benefits of technology

[0007]The present invention is associated with the discovery of important benefits that result from the treatment of feedstocks comprising a fatty acid- or triglyceride-containing component, in order to remove contaminants that have been found to be detrimental in the conversion of such feedstocks to hydrocarbons, and especially biofuel fractions such as diesel or aviation biofuels. Without being bound by theory, contaminants contributing to the presence of trace elements in animal fats and/or plant oils, as components of feedstocks, hinder the ability to catalytically conv...

Problems solved by technology

Without being bound by theory, contaminants contributing to the presence of trace elements in animal fats and/or plant oils, as components of feedstocks, hinder the ability to catalytically convert these feedstocks to hydrocarbons using hydroprocessing.
For example, cer...

example

[0032]A representative plant oil, namely camelina oil, as a feedstock for biofuel production, was analyzed for trace metals by inductively coupled plasma atomic emission spectrometry (ICP-AES). Three jars were then filled with 100 ml each of this feedstock, and 10 g of a different ion exchange resin was added to each jar. In particular, these resins were (1) a strong base anion exchange resin having quaternary ammonium functional groups in the hydroxide form, (2) a weak base anion exchange resin having amine functional groups, and (3) a strong acid cation exchange resin having sulfonic acid functional groups in the hydrogen form. The jars containing resin and camelina oil were subsequently sealed and shaken manually for 5 seconds, before being placed onto a mechanical shaker. After 3 days of mechanical shaking, the resulting, treated oil samples were filtered from the resins and submitted for the same ICP-AES analysis. The feedstock analyses, both prior to and after treatment, as we...

Abstract

Methods are disclosed for the treatment of feedstocks comprising a fatty acid- or triglyceride-containing component to remove contaminants that are detrimental to the conversion of such feedstocks to hydrocarbons, and especially biofuel fractions such as diesel or aviation biofuels. Contaminants contributing to the presence of trace elements in animal fats and/or plant oils, as components of feedstocks, hinder the ability to catalytically convert these feedstocks, for example by hydroprocessing, to biofuels.

Description

STATEMENT OF PRIORITY[0001]This application claims priority to U.S. Provisional Application No. 61 / 428,640 which was filed on Dec. 30, 2010, the contents of which are hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]Aspects of the invention relate to the pretreatment of feedstocks comprising a fatty acid- or triglyceride-containing component (e.g., an animal fats or a plant oil) to remove contaminants such as phosphorous that are detrimental to hydroprocessing operations used to convert such feedstocks to hydrocarbon-containing biofuels (e.g., a diesel biofuel or an aviation biofuel).DESCRIPTION OF RELATED ART[0003]Environmental concerns over fossil fuel greenhouse gas (GHG) emissions have led to an increasing emphasis on renewable energy sources. The production of biofuels is expanding at a rapid pace worldwide as a result of commitments to GHG reduction, including the climate agreement at Kyoto and associated European Union directives. Increasing petrol...
