  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Exergetic performance assessment of gasification and pyrolysis processes of pre-treated wood board wastes

    This paper investigates exergetic performance of gasification and pyrolysis processes and compares their exergy efficiencies, using the experimental data on a two-step process of thermo-chemical conversion of Wood Board (WB) wastes. The exergy values of biomass samples change from 17.49 MJ/kg to 24.57 MJ/kg, respectively. Hydrogen produced from pyrolysis step of gasification varies between 17 ...

  • The conversion of acetol during the concentration process from wood vinegar

    Acetol, as one of the components of biomass pyrolysis liquid, is a high value-added compound for medicine synthesis. If acetol can be extracted from the renewable pyrolysis liquid, much environmental and economic benefit may be obtained; but the instability of acetol makes its concentration difficult. To clarify what compounds are formed from acetol during the distillation process, the components ...

  • Behavior of Flame Spread Downward over Thick Wood Sheets and Heat Transfer Analysis

    To investigate the flame spreading mechanism over charring materials under natural convection, wood sheets from 0.9 to 3 mm thickness have been chosen. The variation of mean flame spread velocity V with thickness  is measured. Typical flame shapes over the wood surfaces are recorded using CCD. The temperature fields in the gas phase are examined by a set of fine thermocouples. On the basis ...

  • Paper fibers as a carbon source for the de novo formation of polychlorinated dioxins and furans

    The formation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) from carbon that was produced by the pyrolysis of paper fibers and from wood charcoal was investigated experimentally. Fibers obtained from filter paper were pyrolyzed at 300° and 800°C to produce low- and high-temperature carbon samples. The two types of carbon and wood charcoal were mixed with silica ...

  • Studies on behaviour of a DI diesel engine fuelled with bio oil biodiesel emulsions

    This paper discusses the results on the use of Jatropha methyl ester (JME) - Wood pyrolysis oil (WPO) emulsion as an alternative fuel in a compression ignition (CI) engine. Three different emulsions were prepared by adding WPO in 5%, 10% and 15% by volume with JME 95%, 90% and 85% by volume respectively using a surfactant Span 20 at 4% on volume basis. The engine behaviour in terms of the ...

  • Biochar application to soils - a critical scientific review of effects on soil properties, processes and functions

    EXECUTIVE SUMMARYBiochar application to soils is being considered as a means to sequester carbon (C) while concurrently improving soil functions. The main focus of this report is providing a critical scientific review of the current state of knowledge regarding the effects of biochar application to soils on soil properties, processes and functions. Wider issues, including atmospheric emissions ...

  • Preliminary studies of lignocellulosics and waste fuels for fixed bed gasification

    This study was carried out to understand the decomposition behaviour of a range of biofuel and waste feedstock during gasification in a downdraft gasifier. A laboratory scale large sample thermogravimetric analyser (LSTA) is used which allows the data on burn-out characteristics of different fuel particles to be measured under agitated conditions. The conditions chosen simulate the combustion ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...

  • Mixed MSW composting in transition

    WITHOUT a doubt, composting the mixed municipal solid waste stream is a “niche” business. It is an MSW management option that seems to be viable in very specific situations. In some instances, these plants were built to service tourist destinations, often in somewhat rural areas where recycling is difficult and landfills are distant. In several other cases, public agencies built plants to extend ...
