This study explores optimal operating conditions for power generation from wet ethanol in a HCCI engine using exhaust gas heat recovery. Wet ethanol is a difficult fuel to ignite as it requires high compressed gas temperatures to achieve ignition causing the requirement for substantial intake...

Since ethanol is considered an essential additive for biofuel production, there may be the opportunity to employ it as such in Mexico. However, an analysis of the ethanol supply chain should be performed first. Therefore, in order to analyze the main variables of the ethanol supply chain, as...

The paper presents a new thermochemical process for the production of isobutanol, which is an excellent biobased gasoline blendstock. The main feedstock for the process is glycerine, obtained as a byproduct in biodiesel production, being used together with methanol. The process was modeled in...

To meet rising energy demands in a sustainable manner, the United States Renewable Fuel Standard 2 (RFS2) mandates the production of 3.78billion L (1billion gallons) of biomass-based biodiesel per year by 2020. Urban marginal lands, herein defined as lots with poor agricultural potential and...

Major challenges of the modern world: energy security, oil price, resources depletion and climate change, have prompted significant advances in research and development of biomass-derived energy and fuels. Algal biofuels are seen as one of the most promising solutions of global energy crisis and...

Biomethane is a gaseous energy vector with a distribution system (the natural gas grid) in place. Biomethane may be produced through thermal gasification of Willow and may be used as a source of renewable heat. Two scales were assessed: a 50MWth facility based on indigenous Willow and a 300MWth...

Global threats of fuel shortages in the near future and climate change due to green-house gas emissions are posing serious challenges and hence and it is imperative to explore means for sustainable ways of averting the consequences. The dual application of microalgae for phycoremediation and...

The growth of energy demand and limited fossil fuel resources lead to renewable energy development such as vegetable oils and animal fats or their derivatives. In the present work, the valuation of waste fish fat by the pyrolysis technique with the presence of catalyst to produce biofuel for...

With rapid economic development, energy consumption in China has tripled in the past 20years, exceeding 2.8 billion tons of standard coal in 2008. The search for new green energy as substitutes for nonrenewable energy resources has become an urgent task. Biodiesel is one of the most important...

Combustion and emission characteristics of rapeseed plant oil (RSO) and its blends with diesel fuel have been investigated in a multi-cylinder direct injection diesel engine. Plant oils have high viscosities compared to diesel and this affects the performance and durability of automotive diesel...
