Background Mitigation of greenhouse gas emissions from transportation sources will require implementation of a variety of strategies, including improvements in the efficiency of overall vehicle/fuel systems, such as hybrid and new high-efficiency diesel engines, and use of synthetic fuels to replace or supplement petroleum-based fuels. A particularly attractive class of synthetic fuels is oxyge...

BACKGROUND Recent metabolic engineering efforts have generated microorganisms that can produce biofuels, including bio-jet fuels, however these fuels are often toxic to cells, limiting production yields. There are natural examples of microorganisms that have evolved mechanisms for tolerating hydrocarbon-rich environments, such as those that thrive near natural oil seeps and in oil-polluted wate...

Two-stage gasification allows power production from biomass and waste with high efficiency. The process involves pyrolysis at about 550°C followed by heating of the pyrolysis gas to about 1300°C in order to crack hydrocarbons and obtain syngas, a mixture of H2, CO, H2O and CO2. The second stage produces soot as unwanted by-product. Experimental results are reported on the suppression of soot fo...

Bio ethanol is an attractive, sustainable energy source to fuel transportation, produced from kinds of biomasses. Among kinds of biomass, lignocellulosic biomass is a very useful feedstock to economically produce environmentally friendly biofuels. The main goal of the research described in this paper is to investigate the process of pretreated biomass, acid or enzymatic hydrolysis, Fermentation...

Nanopalladium catalysts can be synthesized by the precipitation of palladium (Pd) on the surface of bacteria leading to the production of biogenic Pd nanoparticles (bio-Pd). For example, Shewanella oneidensis can reduce Pd(II) and subsequently precipitate it as Pd(0) nanocrystals on their cell wall and in their periplasmic space when a hydrogen donor is provided (De Windt et al., 2005). No expe...

Power system is a combination of a number of sources and loads properly linked by a transmission system. The source is a generating system fueled by renewable or non renewable system where bio mass fuel is used to generate electric power. Due to low levels of bio fuel availability, the gas turbine system is considered as a weak system when compared to thermal and hydro systems. However, stable ...

Biomass derived fuels are preferred as alternative fuels for IC engine due to its abundant availability and renewable nature. In the present work, the complete replacement of diesel fuel with bio-fuels is studied, where the bio-fuels, namely, methyl ester of palm kernel oil and eucalyptus oil were chosen and used as fuel in the form of blends. Various proportions of palm kernel oil and eucalypt...

BACKGROUND Shortages in fresh water supplies today affects more than 1 billion people worldwide. Phytoremediation strategies, based on the abilities of aquatic plants to recycle nutrients offer an attractive solution for the bioremediation of water pollution and represents one of the most globally researched issues. The subsequent application of the biomass from the remediation for the producti...
