Hydrogenated soy ethyl ester (HySEE) from ethanol and waste vegetable oil
- Univ. of Idaho, Moscow, ID (United States); and others
Biodiesel is gaining recognition in the United States as a renewable fuel which may be used as an alternative to diesel fuel without any modifications to the engine. Currently the cost of this fuel is the factor that limits its use. One way to reduce the cost of biodiesel is to use a less expensive form of vegetable oil such as waste oil from a processing plant. These operations use mainly hydrogenated soybean oil, some tallow and some Canola as their frying oils. It is estimated that there are several million pounds of waste vegetable oil from these operations. Additional waste frying oil is available from smaller processors, off-grade oil seeds and restaurants. This paper reports on developing a process to produce the first 945 liters (250 gallons) of HySEE using recipes developed at the University of Idaho; fuel characterization tests on the HySEE according to the ASAE proposed Engineering Practice for Testing of Fuels from Biological Materials, X552; short term injector coking tests and performance tests in a turbocharged, DI, CI engine; and a 300 hour screening test in a single cylinder, IDI, CI engine.
