Problems solved by technology

The mixtures may be complex.
The processing of biofuels is not without problems.
The presence of the resulting “extra” water can cause problems with processing biofuels and biofuel feedstocks.

example 1

[0030]A sample of a biodiesel prepared from meth ester palm oil and having a an initial haze rating determined according to ASTM D-4176 of 4 was tested by admixing the sample with the demulsifiers set forth below in Table 1. The resulting haze values and the times noted are also set forth in the tables. A visual comparison is presented in FIG. 1 for Sample A. The Samples used were:[0031]Sample A is a blend of oxyalkylated acid catalyzed amylphenol resin and oxyalkylated polypropylene glycol available under the trade designation BIO9973 Additive from the Baker Petrolite Corporation;[0032]Sample B is a blend of oxyalkylated nonylphenol resin and an oxyalkylated acid catalyzed butylphenol resin available under the trade designation BIO-9971 Demulsifier from the Baker Petrolite Corporation;[0033]Comparative Sample C is a blend of oxyalkylated base catalyzed butyl / nonyl phenol resin, oxyalkylated base catalyzed butylphenol resin, oxyalkylated base catalyzed amylphenol resin, and oxyalkyl...

example 2

[0035]A sample of a biodiesel prepared from methyl ester palm oil and having a an initial haze rating determined according to ASTM D-4176 of 6 was tested by admixing the sample with the demulsifier set forth below in Table 4. The resulting haze values and the times noted are also set forth in Table 4. A visual comparison is presented in FIG. 1.

example 3

[0036]Chicken fat was rendered to produce an oil. The resultant oil was treated with methanol and a caustic catalyst at from about 140 to about 145° F. to transesterify the oil to produce a very wet biodiesel. The wet biodiesel was treated with 250 ppm Sample B. The biodiesel cleared very quickly and water coalesced and was collected.

Abstract

Water may be removed from a biofuel or biofuel intermediate by using a demulsifier. The demulsifier includes the product of oxyalkylating a resin prepared from a formulation including a phenol and a compound selected from the group consisting of an aldehyde, a diamine a polyamine and mixtures thereof. The demulsifier may also be used with admixtures of biofuels, biofuel intermediates, or biofuel feedstocks with conventional hydrocarbons.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. provisional Patent Application No. 61 / 057673 which was filed on May 30, 2008, and which is fully incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a method for clarifying and removing metals from biofuels. The present invention particularly relates to clarifying and removing metals from biodiesel.BACKGROUND OF THE PRIOR ART[0003]It is well known that as the cost of crude oil increases, numerous efforts have been made to find and develop alternative fuels, particularly fuels that have a renewable, rather than a limited, source. Considerable effort has been expended researching potential fuels from regenerable biological sources, or biofuels. Biodiesel is a diesel fuel-equivalent, processed fuel derived from biological sources (such as vegetable oils), which may be used in unmodified diesel engine vehicles.[0004]In the context herein, biodiesel fuels incl...
