Patent number: 8481771Abstract: Processes for producing biodiesel compositions are disclosed. FFAs present in the triglycerides can be removed by reaction with isobutylene, or by Kolbe electrolysis. The Kolbe electrolysis can be performed on the starting material, or on the crude glycerol. The triglycerides are transesterified to form alkyl esters of the fatty acids and glycerol. The transesterification reaction can be catalyzed by an alkoxide, rather than a hydroxide, to help keep the glycerol by-product dry. The alkoxide salt can be neutralized by reaction with a dry acid, such as gaseous hydrogen chloride or sulfuric acid, and the resulting alcohol removed by distillation, and at least a portion of the neutralized salt can be removed by filtration or decantation. The process can provide improved biodiesel yields, and glycerol pure enough for use directly in glycerol ether manufacture.Type: GrantFiled: March 21, 2008Date of Patent: July 9, 2013Assignee: CPS Biofuels, Inc.Inventors: David Bradin, Guerry L.

Publication number: 20130132155Abstract: A method and system to identify suitable installation sites for alternative fuel stations. The system uses geocoded data sets and other data pertaining to a particular geographic market to generate three models: (1) the system generates a market capacity model that indicates the total number of stations that could be sustained by the present and/or projected consumer demand for alternative fuel within the market; (2) the system generates a hotspot model that indicates the geographic variation of estimated demand for alternative fuel within the market; and (3) the system generates a trade area model that indicates which locations within the market are quickly accessible by a sufficiently high number of alternative fuel consumers. When combined, these three models permit a user of the system to identify and analyze those locations within the market that are most suitable as alternative fuel station sites.Type: ApplicationFiled: September 14, 2012Publication date: May 23, 2013Applicant: Propel Biofuels, Inc.Inventors: Rob Elam, Michael Kudriavtseff, James Mark Austin
