  • Putting the brakes on biodiesel

      Come December 31st, the Texas Commission on Environmental Quality (TCEQ) is set to effectively ban biodiesel in the state’s largest markets. The problem, they say, lies with the fuel’s nitrogen oxide (NOx) emissions and their contribution to the formation of ground-level ozone in Texas’ eastern counties. According to the TCEQ, biodiesel does not meet the stricter NOx standards recently ...

  • Production optimization and quality assessment of biodiesel from waste vegetable oil

    Biodiesel production is worthy of continued study and optimization of production procedures because of its environmentally beneficial attributes and its renewable nature. In Egypt, millions L of oil used for frying foods are discarded each year into sewage systems. Thus, it adds to the cost of treating effluent or pollutes waterways. This study is intended to consider aspects related to the ...

  • Parametric study of biodiesel quality and yield using a bench-top processor

    Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

  • Monoglycerides reduction in rapeseed oil transesterification for production of high quality biodiesel

    Monoglycerides are intermediate by products in rapeseed oil transesterification. If they are present in the bio-fuel and the bio-fuel is used in vehicles, then they can form crystal at cold climate and block fuel injection system of the vehicles. To solve this problem kinetic study of transesterification of rapeseed oil has been carried out in this study. The process variables such as reaction ...

    Rates of use of biological raw materials in a fuel sector are achieved by fast turns. Leading positions in production of bioethanol, absolutely are belonged to Brazil and the USA, development of BioDiesel blend fuel solid grows in the different European Union countries. What is the biofuel? This fuel doesn’t possess a benzol smell and is made from oils as raw materials for which the plants ...

  • Safe environment using biodiesel blend

    The biodiesel blend is more environmentally friendly, than standard types of fuel which has a crude oil base. It only radiates the carbon dioxide necessary for growth of plants. It doesn’t contain sulfur and other unfriendly contaminates. It has better burning process, because there is more mass of oxygen and it is biological product which quickly decays therefore doesn’t threaten ...

  • Biodiesel Analysis With Portable Midinfrared Analyzers

    Biodiesel sales in the U.S. increased from 75 million gallons in 2005 to 250 million gallons in 2006. As ol September 2007, 165 companies arc producing biodiesel and 85 plants are under construction- Along with this rapid growth in production is the iuviI to ensure quality product* Methods fur specifications offinished biodiesel fuels include ASTM D 6751, ON 14214, and DIN 51606. The rest ...

  • Meeting the challenges of biodiesel blend measurements

    In a published paper on biodiesel blend quality submitted by the National Renewable Energy Laboratory1, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For fleet managers, an incorrect blend can mean a total shutdown of operations. On the ...

  • Making biodiesel blends fuel is simple

    Biodiesel is made in the process of transesterification of vegetable oil by methanol, although sometimes ethanol or isopropyl alcohol are used instead. The ration is approximately 200 kg of methanol per 1 ton of oil (plus potassium or sodium hydroxide). Process temperature is approximately 60°С, no pressure increase is required. After the transesterification reaction, the content of ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...
