  • Microtox aquatic toxicity of petrodiesel and biodiesel blends: The role of biodiesel's autoxidation products

    The authors investigated the acute Microtox toxicity of the water accommodated fraction (WAF) of six commercial soybean biodiesel/petrodiesel blends at different oil loads. We analyzed five fatty acid methyl esters (FAMEs), C10–C24 n‐alkanes, four aromatics, methanol, and total organic carbon (TOC) content. At high oil loads, the WAFs' toxicity was significantly higher for blends containing ...

  • GHG balance of biodiesel production and consumption in EU

    The promotion of biofuels as energy for transportation in the industrialised countries is mainly driven by the perspective of oil depletion, concerns about energy security and global warming. Nevertheless, the production of biofuels entails emissions to the environment coming from the different stages in the product life cycle. This paper evaluates the environmental impact of pure rapeseed ...

  • Anaerobic treatment of crude glycerol from biodiesel production

    In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas ...

  • Production of biodiesel from pentaclethra macrophylla seed oil

    In the present work, the potentials of pentaclethra macrophylla (Africa oil bean) seed oil (PMSO) are evaluated for the first time as a feedstock for biodiesel. Methyl (PMFAME) and ethyl (PMFAEE) esters of PMSO were produced by standard transesterification procedure using potassium hydroxide (KOH) as catalyst and their qualities determined. Gas chromatography mass spectrometry (GCMS) runs of the ...

  • 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 ...

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • Future of diesel engines with biodiesel economy

    Biofuel is a fuel from biological raw materials. Any animal or vegetable fat can become raw materials for production of the natural diesel practically. Biodiesel economy is really changed after technology was allowed to make fuel from algas, commercial crops, animal fats and even the fulfilled culinary oils can become the most widespread source of fats. This fuel is safe in production and use, it ...

  • Integration of the soybean production chain and biodiesel: an international parallel to the Brazilian biofuel

    Increasing energy use, climate change and carbon dioxide (CO2) emissions from fossil fuels make switching to biofuels a high priority. Demand for biofuel, specifically based on biodiesel, should change the composition of Brazilian exportation of soybean agro–industrial system. Studies of agricultural chains have drawn attention to important roles including international and domestic market, ...

  • Graphical exergy analysis of reactive distillation column for biodiesel production

    This paper brings the novelty of the exergy analysis technique using Ex–N–A diagram to a packed reactive distillation (RD) column for biodiesel production. In this study, biodiesel is produced through the esterification of fatty acid with methanol. The simulation of the column was performed based on the non–equilibrium (NEQ) model of a three–phase packed RD system. The graphical Ex–N–A method was ...

  • Energy analysis and potentials of biodiesel production from Jatropha Curcas in Tunisia

    Oleaginous plants such as Jatropha Curcas Linnaeus (JCL), not intended for human consumption but used for biodiesel production, could contribute to beneficial outcomes. This plant grows on poor land (arid and marginal land) and is drought resistant. Jatropha Curcas is native to South America and widely grown in South and Central America, Africa, and Asia (Achten et al., 2007; Kumar et al., 2011). ...

  • 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 ...
