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...

Oleaginous plants such as Jatropha Curcas Linnaeus (JCL), not intended for human consumption but used for biodiesel production, could contribute to beneficial outcomes. This plant grows on poor land (arid and marginal land) and is drought resistant. Jatropha Curcas is native to South America and...

A fuzzy logic based method of energy efficiency assessment of Biomass-based Fuel Ethanol (BFE) production is introduced in this paper. Energy relevant inventory variables are defined and described by fuzzy sets representing the differences in energy inventory data between the BFE system and its...

Biomass based fuel technologies are rapidly developing and the barriers in implementing such technologies are being identified to achieve their widespread commercialisation. The two most common biofuels are biodiesel and bioethanol. About 500 million litres of ethanol is required in India itself...

Being a by-product of the well-established charcoal industry, slow pyrolysis bio-oil can be an excellent, cost-effective and renewable liquid fuel. However, even in Brazil, a country with a very clean energy profile and large-scale charcoal production, bio-oil is not properly utilised yet. A...

Apart from cost, the net production of energy is the most important factor in evaluating the feasibility of producing renewable fuels from woody biomass. Unlike sugar, the effort required to make woody materials fermentable is considerable, and has been a major barrier to the use of such...

There is scope internationally to utilise surplus and degraded agricultural land for biomass crops that might also be environmentally beneficial. For example, dryland salinity in southern Australian could be ameliorated using profitable woody biomass crops. A model was developed to predict...

Although challenges like global climate change and oil depletion will increasingly drive fuel selection, increasing bioenergy use is only one of many possible responses to these problems. Present biomass liquid fuels are almost all derived from food crops, but their potential for further...

An exploratory comparative study of the fast and slow pyrolysis of eucalyptus mallee has been carried out to explore the differences in liquid yields and characteristics. The study focused on the liquid products, which were fully characterised and good mass balance closures were achieved. The...

In this paper, the research results obtained on the influences of biodiesel on the components of an engine are presented. The study was carried out at the Dumlupinar University in Turkey. Biodiesel has been an alternative fuel for diesel engines since 1900s. However, the use of biodiesel has...
