Reliable Determination of Copper, Phosphorus and Sulfur in Bioethanol Using Inductively Coupled Plasma Spectrometry
The increased strain on existing fossil fuels has led to a rise in demand for alternative fuel production. Bioethanol is ethanol produced from the fermentation of sugar derived from plants such as sugar cane or beet, maize or cassava. The production of bioethanol for use as either a fuel substitute or a blending agent for gasoline has increased dramatically over the past few years. The USA produced an estimated 23.3 billion liters of bioethanol in 2007 compared with 16.2 billion liters in 2005....
Accurately Quantify Methanol and Ethanol in E85 Biofuel by D5501 with New Rtx®-DHA-150 Column
Ethanol and methanol levels in biofuels must be accurately determined as they impact fuel performance and influence sales price. Since fuel ethanol must be denatured with gasoline to render it nonpotable prior to transport, analysis is complicated by the presence of gasoline hydrocarbons. Testing is usually done according to ASTM Method D5501, which recommends either a 100m or a 150m column. This method currently targets the determination of ethanol at 93-97% and methanol at 0.1-0.6%, based o...
Determination of Total FAME and Linolenic Acid Methyl Ester in Pure Biodiesel (B100) by GC in Compliance with EN 14103
Interest in biodiesel as a clean-burning alternative fuel produced from renewable sources such as vegetable oils has risen considerably over the last few years. It is the only alternative fuel to be legally registered with the US EPA and to have fully completed the health effects testing requirements of the 1990 Clean Air Act Amendments. ?Pure? biodiesel (B100) has been designated as an alternative fuel by the US Department of Energy (DOE) and the US Department of Transportation (DOT).
New Analyzer Provides Measurement of % Biodiesel (% FAME) in Petrodiesel from 0.025% to 20% Range
A2 Technologies has developed a new FTIR analyzer and a new sampling methodology which enables the measurement of % FAME present in diesel fuel in the analytical range from 0.025% to 20%. This new technology is fast, easy-to-use and exceptionally reliable for on-site measurement of % FAME in blended fuels, as well as a highly accurate meter for determining ppm levels of FAME contamination in petrodiesel. The analyzer can also be configured to measure % FAME in diesel fuel from 1% to 100%, for a...
