  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • A Biodiesel Filled Future For Your Car - case study

    Future vehicles require a level of robustness to the legislated future introduction of bio-diesel. This research aims to understand the future of biodiesels in world markets and the characteristics of these fuels. The Need In recognising that sustainable sources of biodiesel will be dependant upon the particular local circumstances where the raw naterial is sourced, the ...

  • On the effect of a global adoption of various fractions of biodiesel on key species in the troposphere

    Biodiesel use is being promoted worldwide as a green alternative to conventional diesel. A global three-dimensional chemistry transport model is employed to investigate the impact on air quality and global tropospheric composition of adopting biodiesel as a fractional component of diesel use. Five global simulations are conducted where emission changes of hydrocarbons and nitrogen oxides were ...

  • Experimental investigations on diethyl ether as fuel additive in biodiesel engine

    In this work, biodiesel (methyl esters) is produced from unrefined rubber seed oil by two-step transesterification process. Biodiesel engines are prone to cold-starting problems in winter seasons and emit more nitrogen oxides. To overcome these problems, diethyl ether is used as a fuel additive for biodiesel. The lower percentage addition of diethyl ether with biodiesel improves the engine ...

  • Economic Feasibility of Sustainable Non‐Food Feedstock Based Biodiesel Production:Castor

    Castor is an important non-edible oilseed crop of the family Euphorbiaceae with great utilitarian value in industry, agriculture and pharmaceutical sectors. The presence of hydroxyl group and double bonds in ricinoleic acid imparts unique chemical and physical properties for castor oil which makes castor oil a vital industrial raw material and stabilizes the oil against oxidation. ...

  • Performance of a direct diesel engine using aviation fuels blended with biodiesel

    In this study, jet fuel (JF) and railroad fuel (D2) with SME blends (5%, 20%, 50%) were used in a four–cylinder, naturally aspirated, direct (DI) diesel engine. The engine was operated under full load and tested at various speeds to determine the engine's performance and exhaust emission characteristics. The experimental results show that as the SME ratio of the fuels increases, the break ...

  • Combustion, performance and emission characteristics of a DI CI engine using biodiesel with varied fatty acid composition

    Five Biodiesel produced from different vegetable oils were tested on a diesel engine to study the effect of biodiesel fatty acid composition specifically unsaturated composition on the engine combustion. The results from fuel analysis show that biodiesel (93% unsaturated fatty acid ester composition) with 55% linolenic ester has a higher density of 0.89 kg/m³, lower viscosity of 3.8 cSt, heating ...

  • Selection of best biodiesel blend for IC engines: an integrated approach with FAHP–TOPSIS and FAHP–VIKOR

    The aim of this study is to select the best blend using multi–criteria decision–making (MCDM) technique. The six alternative fuel blends diesel, B20, B40, B60, B80 and B100 are prepared by varying the amount of diesel in biodiesel. Brake thermal efficiency (BTE), exhaust gas temperature (EGT), oxides of nitrogen (NOx), smoke, hydrocarbon (HC), carbon monoxide (CO) and carbon ...

  • Combustion and emission characteristics of a diesel engine fuelled with biodiesel having varying palmitic acid, stearic acid and oleic acid in their fuel composition

    The present work discusses the performance and emission characteristics of blends of vegetable oil esters with varying saturated fatty acid composition tested on a stationary direct injection compression ignition engine. Saturated fatty acids are long-chain carboxylic acids that usually have between 8 and 24 carbon atoms and have no double bonds. The unsaturated fatty acids resemble saturated ...

  • A hybrid multi–criteria decision support system for selection of optimum fuel blend

    The increasing diesel consumption, depletion of fossil fuels and environmental concerns have prompted usage of biodiesel. The selection of appropriate source and blending of biodiesel plays a role in alternate energy production. The aim of this study is to evaluate the optimum blend using Multi Criteria Decision Making (MCDM) technique. Five alternative fuel blends are prepared by varying the ...

    In this investigation, cotton seed methyl ester (CSME) was prepared by transesterification using potassium hydroxide (KOH) as catalyst. The engine performance was analysed with different blends of biodiesel and was compared with neat diesel. It was concluded that the lower blends of biodiesel are closer to diesel as far as thermal efficiency is concerned. In the lower blends, the brakes specific ...
