“…The direction in which the fluid passes through the fuel establishes where the different reaction zones are located [76] and distinguish, in turn, three different subtypes of fixed-bed reactors: updraft, downdraft and cross-flow. The first has a counter-current flow of gasification agent, the second has a cocurrent flow, and in the third case the fluid is introduced by one side, exiting by the opposite.…”

“…Electrical efficiencies of micro-scale plants are between 13% and 25% [76,79,[122][123][124][125][126][127] and total efficiencies between 60% and 74% [124,126]. At small-scale level, slight increases are found: electrical efficiencies are 12.5-28% [56,101,122,123,128,129] and total efficiencies can reach 96% [122].…”

“…In an analogous way, there are differences between the gasification technologies: fixed bed reactors, in particular the downdraft ones due to their low tar content of the produced gas [74,76], require lower investments [75] and engine cleaning operations [14] than fluidized bed reactors. Therefore, fixed bed reactors are the most suitable alternative for small-scale gasification applications [58,101] that are constrained to have low O&M costs [64,157] while fluidized beds have been claimed to be more appropriate for mid-and large-scale applications [58,67,81,101].…”

“…Vários estudos têm sido desenvolvidos para avaliar o impacto ambiental da produção de biocombustíveis. Boloy et al (2011) avaliaram e quantificaram o impacto ambiental do uso de gás de síntese em conjunto motor de combustão interna/gerador que funciona associado a um gaseificador de biomassa tipo downdraft . No estudo foram determinadas as emissões de gases poluentes e material particulado, além da eficiência ecológica do sistema proposto.…”

RESUMOO presente trabalho tem como objetivo quantificar o impacto ambiental da produção simultânea de biodiesel e hidrogênio. Estudos sobre a utilização de biodiesel e hidrogênio têm se mostrado promissores no ponto de vista da eficiência energética, mas é preciso atingir um maior potencial comercial. Aspectos econômicos e ambientais são considerados limitantes para o desenvolvimento tecnológico destes biocombustíveis. Entretanto, em se tratando de uma área em expansão, tonar-se necessário atrelar a essa tecnologia práticas efetivas de sensibilização ambiental tanto para as Instituições de Ensino Superior -IES, bem como para a população. Neste artigo, determinam-se as emissões de dióxido de carbono equivalente em cada etapa do processo produtivo: plantio, transporte, extração de óleo e produção de biodiesel e hidrogênio; seguindo o mecanismo de desenvolvimento limpo com biodiesel apresentado na convenção das nações unidas sobre mudança do clima (UNFCCC-2010). A etapa associada ao transporte foi a que apresentou menor emissão de dióxido de carbono equivalente, apenas 1% do valor total das emissões produzidas; já a etapa agrícola, produz 80% do valor total das emissões. O binômio biodiesel e hidrogênio representa uma inovação tecnológica, visto que do ponto de vista ambiental consegue-se uma redução das emissões do dióxido de carbono equivalente. Por isso, essa pesquisa contribui para a discussão acerca dos conceitos de inovação tecnológica e sustentabilidade levando em conta a qualidade ambiental dos processos produtivos e de seus produtos.

“…Other studies in literature have highlighted that ICE fed with syngas have useful power lower than those fed with natural gas (NG) due to relatively low values of LHV of syngas [8,9,10,11]. Moreover, it is necessary increase the airflow during the combustion process to minimize the reduction of effective power [12,13,14]. The ICE fueled with syngas need of an index of excess air (λ) with values variable between 1.25 e 2.50 [7].…”

Biomass is an alternative source to fossil fuels as proven by the increase of the primary energy production of 6.1% between 2012 and 2013. In European countries, the biomasses are 3.5% of renewable energy sources and they have a strategic role to reach the objective established by the European Directive 2009/28/CE. However, it is necessary to increase the use of renewable fuels, as syngas and biogas, to satisfy the objectives of the UE in the field of renewable energies and greenhouse gas emissions. The gasification and pyrolysis processes to produce syngas are promising technologies for a practical use of the biomass. In this context, gasification of biomass from agro-forestry activities is considered among the most effective sustainable technologies to recover waste that otherwise would be difficult to dispose. The micro-CHP electrical and thermal power were calculated through a balance of mass and energy based on an input-output model of the overall system. The results of this study demonstrated that it is possible to produce thermal and electrical energy for small agro-industries through the valorization of the residuals biomass deriving by their activities.
