  • Maintaining biodiesel quality standards

    A problem that is sometimes encountered with biodiesel blends is inaccurate blend ratios. This article describes a quick analytical method to assess blend ratios and ensure fuel performance. According to a study1 done by the National Renewable Energy Laboratory, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry ...

  • 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 ...

  • 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 ...

  • Modification of thermal and oxidative properties of biodiesel produced from vegetable oils

    Trans esterification of three vegetable oils, sunflower oil, linseed oil and mixed oils as; sunflower-soyabean and olein were carried out using methanol, and potasium hydroxide as catalyst. The methyl esters of the corresponding oils were separated from the crude glycerol and characterized by physical-chemical methods to evaluate their thermal ...

  • Hielscher – Ultrasonic Transesterification of Oil to Biodiesel Improves Reaction Speed and Yield

     Ultrasonication can improve the conversion processing of vegetable oils or animal fats to biodiesel by improved mixing and enhanced chemical activity. The manufacturing of biodiesel from oils (e.g. soy, canola, sunflower seed) or animal fats, involves the base-catalyzed transesterification of fatty acids with methanol to give the corresponding methyl esters. The conventional esterification ...

  • Optimum reaction time, performance and exhaust emissions of biodiesel produced by microwave irradiation

    While transesterification is well established, there remain considerable inefficiencies in existing transesterification processes. In this study an alternative energy stimulant, ‘‘microwave irradiation’’ was used for the production of the alternative energy source, biodiesel. The optimum parametric conditions obtained from the conventional ...

  • Sustainability assessment of microalgal biodiesel production processes: an exergetic analysis approach with Aspen Plus

    Biodiesel production growth rate keeps increasing every year with the hope of replacing fossil based liquid fuel which is near exhaustion. Energy efficiency methods coupled with environmental and economic sustainabilities would render biodiesel production attractive. Algal cultivation and oil extraction processes are found to be energy intensive hence exergy destructive. This study presents the ...

  • SLB-IL111 for Petroleum Applications

    Gas chromatography (GC) is commonly employed for many applications in the petroleum industry. Two specific applications, the determination of benzene and other aromatics in gasoline, and the fatty acid methyl ester (FAME) profile of B20 biodiesel, present special challenges and require the use of a highly polar column. The SLB™-IL111 column utilizes a stationary phase with extreme polarity ...

  • Microalgae harvesting and cell disruption: a preliminary evaluation of the technology electroflotation by alternating current

    Some species of microalgae have high productivity and lipid content, which makes them good candidates for biodiesel production. Biomass separation and cell disruption are important steps in biodiesel production from microalgae. In this work, we explored the fundamentals of electroflotation by alternating current (EFAC) with non-consumable electrodes to simultaneously harvest microalgae and ...

  • Fuel alternatives for heavy equipment

    High fuel prices are leading composters and wood grinders to reevaluate diesel-guzzling heavy equipment, looking to alternatives that are both more cost-efficient and environmentally friendly. This could be as “simple” as filling up existing machines with biodiesel blends, could involve swapping out a diesel model for an electric one, or even go as far as generating electricity on site to power ...

  • Fat, oil and grease waste from municipal wastewater: characterization, activation and sustainable conversion into biofuel

    Fat, oil and grease (FOG) recovered by the oil/water separator of a wastewater treatment plant (WWTP) were sampled, characterized, activated and converted into biofuel. Free acids (50–55%) and fatty soaps (26–32%) not only composed the main components, but they were also easily separable from the starting waste. The respective free fatty acid profiles were ...

  • A new way to Skim and save

    Oil and water don’t mix, efficiency and profits often do. While the oil and water adage is well known to biodiesel producers—it means feedstock is contaminated with water—it also offers an opportunity. Biodiesel plant personnel are always looking for new tools and equipment that help a facility operate more efficiently. Oily water is a major hurdle to efficient processing ...

  • Water contamination in fuel: cause and effect

    Water exists in three physical states and depending on the surrounding conditions it finds its way to the fuel systems like the high pressure common rail (HPCR) fuel systems on diesel engines. The important point thereafter is to provide the best possible on-engine protection by securing the fuel injector systems from severe damage. As the environmental challenges and emission regulations become ...
