  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Value stream mapping based on energy and cost system for biodiesel production

    Organisations have to give more attention to customer demands for survival and also for increasing their market shares. But customers' demands are not stable. The main problem of all organisations is how to cut costs during production process. The solution to this problem is built up with lean–based production systems. Value stream mapping identifies those areas where unwanted productivity is ...

  • Progressing cavity pumps for pumping chemically aggressive liquids during biodiesel production

    Progressing cavity pumps reflect an established design with decades of usage in many industries and applications. Pumps of this type embody highly mature technical designs. For many years, improvements and innovations have been at the margins. Examples of design improvements include the 2/3-screw geometry, which is more economical than the 1/2-screw geometry that had been used exclusively for ...

  • A feasibility study on beef tallow conversion to some esters for biodiesel production

    Background:Nowadays, management and recycling of industrial by-products are one of the most important issues in developing and developed countries. Beef tallow is one of these residues produced in slaughter houses and primarily is utilized in soap production industry. However, when this industry is overloaded, the extra fats are usually incinerated or disposed in a sanitary landfill. However, ...

  • Economic Feasibility of Sustainable Non-Food Feedstock Based Biodiesel Production: Pongamia

    In state-of-the-art pilot trials at CJP- the advanced Biofuel center, scientists are working sedulously on various oil seeds, which have the potential to make a significant contribution to resolving the future energy crisis. One of these seeds comes from a tree called Pongamia pinnata. Pongamia is a tree, native to India and found in tropical and subtropical areas around the world. ...

  • 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 ...
