  • The feasibility of producing alcohol fuels from biomass in Australia

    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 materials to produce renewable fuels. The Energy Profit Ratio (EPR) of fossil fuels is declining rapidly as ...

  • Kinetics of xylose in hydrolysate using dilute sulphuric acid as catalyst

    In the technology of manufacturing fuel alcohol from biomass as feedstock, hydrolysis using dilute acid as catalyst is one way to produce fermentable saccharide. In this process, the yield of xylose is always low because of the degrading during the acid environment. In this paper, the degrading kinetics of xylose in the hydrolysate was investigated under the conventional process conditions of the ...

  • Biofuel - Energy Supplier of the Future?

    Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. ...

  • Hydrogenomics of the extremely thermophilic bacterium caldicellulosiruptor saccharolyticus

    Caldicellulosiruptor saccharolyticus is an extremely thermophilic, gram-positive anaerobe which ferments cellulose-, hemicellulose- and pectin-containing biomass to acetate, CO2, and hydrogen. Its broad substrate range, high hydrogen-producing capacity, and ability to coutilize glucose and xylose make this bacterium an attractive candidate for microbial bioenergy production. Here, the complete ...

  • Highmark Renewables receives `Integrated bioRefinery` patent

    A company located in western Canada has received its sixth patent—this one for its Integrated bioRefinery, a trademarked name for its technology. “The patent speaks for itself, it says we are unique and first of its kind and so we are happy to enjoy that protection,” said Evan Chrapko, CEO of Highmark Renewables. The Integrated bioRefinery(TM) starts with an anaerobic digester, ...

  • Commericalizing cellulosic ethanol

    Cellulosic biofuels, produced from nonfood feedstock, are expected to play a critical role in reducing the country's dependence on imported oil. EISA, the Energy Independence and Security Act of 2007, calls for the production of 100 million gallons per year (mgpy) of cellulosic biofuels by 2010, with a longer term goal of 16 billion gallons by 2022.Achieving these goals will not be easy. Several ...
