  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • Biodiesel dispersion replaces diesel fuel

    Is that possible to find substitution to traditional diesel fuel? Until recently these question were asked by ecologists and diesel cars owners who are taking hard time in periodic rises in price of fuel. With the event of the biodiesel development the situation cleared up. It became clear to all that cheap, qualitative and environmentally friendly biodiesel was born and started winning surely ...

  • 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 ...

  • 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 Feedstock Analysis 2nd Generation of Biofuels

    The main obstacle in biodiesel production from waste fats and oils is their high free fatty acid content. Its precise measurement helps Professor Karel Kolomaznik’s Faculty of Applied Informatics team at Tomas Bata University in Zlín (Czech Republic) to develop suitable new technology. Biodiesel from waste The Tomas Bata University ...

  • 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 ...

  • Effect of Biodiesel Fuels on Pollutant Emissions from EURO 3 LD Diesel Vehicles

    Transport is a key factor in modern economies. However, the EU transport system is currently not sustainable, and in many respects moving away from sustainability rather than towards it. The European Environment Agency highlights in particular the sector's growing CO2 emissions that threaten the EU meeting its target under the Kyoto protocol. Transport also represents a key challenge to ...
