  • Supercritical water gasification of ethanol fermentation residue of seaweed: effect of sodium chloride salt

    The effects of sodium chloride salt on the supercritical water gasification of ethanol fermentation residue of seaweed with and without the presence of catalyst (activated carbon) were investigated. The presence of activated carbon did not affect the carbon gasification efficiency. By increasing the salt concentration, the carbon gasification efficiency is reduced until one point, the carbon ...

  • 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 ...

  • Dreyer & Bosse deliver renewable energy CHP project to Sofia in Bulgaria

    The Sofia council decided to invest in renewable energy to make use of the many tons of biowaste (vegetative material),  20,000 tons per annum, from the waste removal collections that take place daily in Sofia and surrounding area. To make this possible it was decided to go for wet fermentation where the substrate or raw material ferments and the biogas is collected. After three weeks the ...

  • 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 ...

  • Energy from biogas

    From an ecological and economical perspective, biogas is an important source of energy. The fossil resources are limited, and they impose a high burden on the environment. A resourceconserving alternative made from biomass poses a different scenario. The raw material is renewable, and conversion only releases as much CO2 as was previously contained by the source material. With the technological ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...

  • 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. ...

  • Optimisation of pressed pericarp fibre delignification for glucose recovery using response surface methodology

    In this study, pressed pericarp fibres (PPFs) were subjected to chemical pretreatment for bioconversion of lignocellulosic biomass to fermentable sugars. The effectiveness and comparison between pretreatments using acid (HCl) and alkaline (NaOH) to reduce the lignin content was studied. Alkali pretreatment showed better lignin removal than acid pretreatment. Subsequent experiments were then ...

  • 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 ...

  • Kickoff for Biogas - South America Opts for Green Energy Made by WELTEC

    Currently, the world is locked on to the FIFA World Cup in Brazil. Though they have already reached a high technical level as far as football is concerned, the South American countries still have development potential in the fields of biogas technology and renewable energies. In the interview, Aguinaldo Ramalho of the German biogas plant manufacturer WELTEC BIOPOWER talks about the potential, ...

  • 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 ...
