  • Influence of precursors on the catalytic activity of alumina for bio-ethanol dehydration in microchannel reactors

    In this paper, the catalytic activity of alumina for bio-ethanol dehydration was studied in a microchannel reactor. Five catalysts were prepared from precursors with different ratios of AlOOH (pseudo boehmite) and Al(OH)3 (bayerite). The physicochemical properties of catalysts were characterised by X-Ray Diffraction (XRD) and Temperature Programmed Desorption (TPD). The influence of reaction ...

  • Parametric study of biodiesel quality and yield using a bench-top processor

    Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

  • Innovative Ammonia Control case study

    Ammonia has increasingly become more of a regulatory concern. Ammonia emissions into the atmosphere have been linked to the formation of fine particulate matter, while ammonia emissions in wastewater are restricted because of the negative affect the chemical has on rivers, lake, and aquifers. Many sources of biofuels contain ammonia or can create ammonia during processing. The following case ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...

  • Kinetics of transesterification crude soybean oil to biodiesel catalysed by magnesium methoxide

    The apparent activation energy of transesterification of soybean oil with methanol was investigated by the use of magnesium methoxide as solid base catalyst. The effect of variations in reaction time and temperature (50-65°C) on the macro reaction rate were studied while the molar ratio of methanol to oil (9 : 1) and the mass ration of catalyst to oil (8 wt%) were held. The experimental data were ...

  • In situ transesterification of non–edible oil in the presence of cetyltrimethylammonium bromide

    In situ transesterification of Jatropha curcas l. seed with base catalysed alcohol in the presence of cetyltrimethylammonium bromide (CTMAB) as phase transfer catalyst (PTC) was investigated. The yield of fatty acid methyl esters (FAME) increased from 49.7 w% to 89.2 w% in the presence of CTMAB as PTC at 240 minutes of reaction time. Similarly, the yield of fatty acid ethyl esters (FAEE) ...

  • Experimental investigations on diesel engine fuelled with methyl esters of cotton seed oil

    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 ...

  • A comparative study of molar ratio effect on transesterification of Jatropha Curcas using kinetic and fuzzy techniques

    Biodiesel is a biodegradable source of fuel that can be synthesised from edible, non-edible and waste oils through transesterification process. In this paper, we presented transesterification reaction of Jatropha Curcas oil by using sodium hydroxide catalyst at 150°C in batch reactor. Further, we designed the fuzzy model of the molar ratio and the performance evaluated by comparing fuzzy model ...

  • The emission characteristics of a compression ignition engine operating on castor oil methyl ester

    Diesel vehicles are a major form of transportation, especially in developing countries. Recent concerns over the environment, increasing fuel prices and the scarcity of its supply have promoted interest in the development of alternative sources of petroleum fuels. In this investigation, castor oil methyl ester was prepared by transesterification using potassium hydroxide (KOH) as a catalyst and ...

  • Process optimisation of base catalysed transesterification of Karanja oil for biodiesel production

    Biodiesel has been receiving increasing attention due to its renewable nature, lower pollution potential and green house gas benefit compared to mineral diesel. There are numerous factors, which affect the yield of biodiesel in a transesterification process such as reaction temperature, molar ratio of alcohol to oil, catalyst concentration, stirring speed, reaction time, etc. These variables are ...

  • 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 ...

  • Biodiesel production from high FFA crude rice bran oil and investigation on its properties as CI engine fuel

    This study is an attempt to convert high free fatty acid (FFA) crude rice bran oil (CRBO) into biodiesel and to evaluate whether the biodiesel obtained meets the biodiesel quality standards prescribed by ASTM D 6751-07b. CRBO was subjected to a two-step transesterification process using HCl and NaOH as acid and base catalyst respectively with a 15% v/v of methanol to oil ratio. This process ...

  • Biodiesel fuel for transportation: Status and issues in the United States

    The United States consumed 3.39 billion barrels of gasoline, 1.54 billion barrels of diesel fuel, and 0.59 billion barrels of jet fuel in 2007. And it currently imports 3.66 billion barrels of oil and petroleum products per year, 65% of US consumption, compared to 1.71 billion barrels (or 36%) 20 years ago. To address the growing gap between petroleum consumption and domestic production, the US ...

  • 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 ...
