The predicted shortage of fossil fuel around the world has encouraged the search for substitutes for petroleum derivatives. This search resulted in an alternative fuel called "biofuel". Alfa Chemistry has been committed to find solutions to alternative energy issues, offering comprehensive testing services for the biofuel supply chain, which include raw biomass products analysis, components analysis, performance analysis, process optimization and development. State-of-the-art analytical equipment in Alfa Chemistry allows us to control the quality of fuel and verify the delivered biodiesel blend ratio, glycerin and pollutant content.
Biofuels, are a form of renewable energies derived from a wide variety of biomass products. It can be theoretically produced from any biological carbon source, though the most common by far is photosynthetic plants. Many different plants and plant-derived materials can be used for biofuel manufacturing. Biofuel industries are rapidly expanding worldwide and biofuels are most commonly applied to power vehicles and for generating heat.
Currently, there are two main forms of biofuels in the market: fuel ethanol and biodiesel (also called FAME (fatty acid methyl ester) in Europe). Fuel ethanol refers to the alcohol fuel converted from various biomass-based materials through the fermentation of microorganisms. Fuel ethanol can be used as a fuel directly, but most often it is blended with gasoline (at about 5-10%) to yield gasohol. Biodiesel is a substance in forms of fatty acid methyl esters (FAME) obtained through transesterification of triglycerides (TG) in vegetable oils, animal oils and recycled restaurant grease. Its effectiveness is no different from that of ordinary diesel, but the major advantage of biodiesel is that the concentration of harmful gases produced during the combustion process is low.
In practical applications, some unconverted oil compounds left in biodiesels (such as TG, diglycerides (DG), monoglycerides (MG) and glycerin) can deposit in the engine, block filters, cause fuel degradation or form toxic emissions, thereby affecting the engine performance. Therefore, it is critical to develop sensitive and reliable analytical methods to monitor and quantify the concentration of these glycerides in various production stages. At present, various regulatory agencies have formulated many standards for biofuel products, including American Society for Testing and Materials (ASTM) standard D6751, D4815 and D4806, as well as European Union standards EN14105, EN 14214 and etc., which aim to control pollutants content and allow bioethanol and biodiesel to be blended into conventional fuels.
