Abstract:One of the most important issues in biomass biocatalytic gasification is the correct prediction of gasification products, with particular attention to the Topping Atmosphere Residues (TARs). In this work, performedwithin the European 7FP UNIfHY project, we develops and validate experimentally a model which is able of predicting the outputs,including TARs, of a steam-fluidized bed biomass gasifier. Pine wood was chosen as biomass feedstock: the products obtained in pyrolysis tests are the relevant model input. Hydrodynamics and chemical properties of the reacting system are considered: the hydrodynamic approach is based on the two phase theory of fluidization, meanwhile the chemical model is based on the kinetic equations for the heterogeneous and homogenous reactions. The derived differentials equations for the gasifier at steady state were implemented MATLAB. Solution was consecutively carried out using the Boubaker Polynomials Expansion Scheme by varying steam/biomass ratio (0.5-1) and operating temperature (750-850°C).The comparison between models and experimental results showed that the model is able of predicting gas mole fractions and production rate including most of the representative TARs compounds.

“…Gate-to-gate material-and energy-based indicators are particularly relevant for resource recovery technologies or nutrients extraction processes from raw materials. For example, the carbon conversion efficiency applied to one gasification process [61] and the phosphorus utilization efficiency calculated for the production of phosphorus-based chemicals [62] have proven to be valuable indicators to identify losses of resources along the process chain, and to compare the strengths and weaknesses of process alternatives. Nevertheless, the completeness of an analysis based on life cycle thinking to evaluate and compare RE should also be pursued.…”

Toward a Framework for Resource Efficiency Evaluation in Industry: Recommendations for Research and Innovation Projects

Abstract:The world is facing a tremendous resource supply challenge. One strategy of regions and nations to address this issue is to encourage research and innovation through funding programs. Most of the time, these programs require that research and innovation projects quantify potential increases in resource efficiency achieved by the projects. However, no consensus exists on how to calculate resource efficiency; therefore, a wide range of approaches is followed. As a result, resource efficiency results are not comparable between projects, and because no rules or guidelines exist to help project developers, the approach followed is not always appropriate. This paper aims to discuss the existing approaches and methods used to evaluate resource efficiency. In this context, resource efficiency is defined as the ratio between the benefits obtained from resources and the impact or amount of resources used. The most challenging step is the determination of this ratio's denominator because a wide range of methods to quantify resource consumption exist and are being used. They can be classified as gate-to-gate or life cycle based methods and can be subdivided into accounting methods and impact assessment methods. Each method considers different aspects of resources; thus, no single method aims to answer the same research questions. Therefore, project developers must make a well informed choice about which method to use. This paper provides recommendations to support this choice, as well as the overall evaluation and the valorization of the resource efficiency ratio in the framework of research and innovation programs.

“…With respect to lignocellulosic biomass, thermal gasification is a promising technology for conversion to gas with as high as 90% cold gas efficiencies (CGE), e.g. [11][12][13]. As minimization of transport distances is important, installation of local small-scale facilities for conversion of biomass should be preferred over centralized plants (provided efficiencies are competitive).…”

“…As minimization of transport distances is important, installation of local small-scale facilities for conversion of biomass should be preferred over centralized plants (provided efficiencies are competitive). Thermal gasifiers have been demonstrated to be competitive with combustion plants at a small-scale (100-600 kWe) [11][12][13][14][15]. Lignocellulosic biomass was therefore assumed gasified for production of syngas with efficiencies as reported in Table S3.…”

“…The long-term political target for Denmark is to reach a 100% renewable energy system in 2050 primarily based on wind power and biomass energy but also involving significant decreases in the national energy demand [2]. Several studies have modeled future sustainable energy systems from a technical perspective [3][4][5][6][7][8][9][10][11][12]. According to these studies, 100% renewable energy systems can only realistically be achieved through significant reductions in energy demand, increased efficiencies of fuel conversion technologies, higher shares of wind power (e.g.…”

Decrease of fossil fuel consumption in the energy sector is an important step towards more sustainable energy production. Environmental impacts related to potential future energy systems in Denmark with high shares of wind and biomass energy were evaluated using life-cycle assessment (LCA). Based on the reference year 2008, energy scenarios for 2030 and 2050 were assessed. For 2050 three alternatives for supply of transport fuels were considered: 1) fossil fuels, 2) rapeseed based biodiesel, and 3) Fischer-Tropsch based biodiesel. Overall, the results showed that greenhouse gas emissions per PJ energy supplied could be reduced by more than half by increased use of wind and residual biomass resources as well as by electrifying the transport sector (from 68 to 17 Gg CO 2 -eq/PJ). Energy crops for production of biofuels and the use of these biofuels for heavy terrestrial transportation were responsible for most environmental impacts in the 2050 scenarios, in particular upstream impacts from land use changes (LUC), fertilizer use, and NO x emissions from the transport sector were critical. Land occupation (including LUC effects) caused by energy crop production increased to a range of 600-2100 10 6 m 2 /PJ depending on the amounts and types of energy crops introduced. Use of fossil diesel in the transport sector appeared to be environmentally preferable over biodiesel for acidification, aquatic eutrophication, and land occupation. For global warming, biodiesel production via Fischer-Tropsch was comparable with fossil diesel.
