The need to produce energy from poor quality carbonaceous materials has increased, in order to reduce European dependency on imported fuels, diversify the use of new and alternative fuels and to guarantee secure energy production routes. The valorisation of a poor quality solid residual fuel (SRF), with high content of ash and volatile matter, through its conversion into fuel gas was studied. The rise of gasifi...

Effect of syngas composition on hydrogen permeation through a Pd–Ag membrane

Pinto, Filomena; André, Rui Neto; Franco, Carlos; Carolino, Carlos; Gulyurtlu, Ibrahim

Hydrogen separation from a syngas mixture with different compositions was studied by using a Pd–Ag membrane. The effect of temperature (from 300 C to 600 C) and of relative pressure (from 0.2 MPa to 0.5 MPa) was studied. In general, rises of both these parameters allowed increasing H2 permeate flux. The Pd–Ag membrane showed to have a great selectivity, as when inlet gas mixture contained different compositio...

Gasification study of cynara cardunculus to produce hydrogen rich gas

Franco, Carlos; Lopes, M. Helena; Pinto, Filomena; André, Rui Neto; Gulyurtlu, Ibrahim; Cabrita, Isabel

The need to substitute fossil fuel feedstocks with endogeneous biomass to produce energy with lower environmental impact makes necessary to develop innovative and technologically more advanced processes for energy production. Gasification of Cynara cardunculus L. (cardoon) alone and mixed with Eucalyptus was carried out in a bench scale fluidized bed gasifier to study the influence of operating parameters that ...

Prediction of H2S and HCl formation during RDF and co-gasification in fluidized...

Gulyurtlu, Ibrahim; Pinto, Filomena; Lopes, M. Helena; André, Rui Neto; Dias, Mário; Cabrita, Isabel

Most solid fuels contain S and Cl and during their gasification, the formation of pollutants such as H2S and HCl becomes inevitable, however, a better understanding of the mechanism involved in their formation and subsequent destruction during the process could help to define operating conditions and to achieve synergy during co-gasification to minimize their emissions. The formation of these pollutants along w...

Desenvolvimento de processos de co-gasificação de carvão com resíduos

André, Rui Neto

Tese apresentada à Universidade de Aveiro para obtenção do Grau de Doutor em Ciências Aplicada ao Ambiente ; Portugal e a maioria dos países da União Europeia são altamente dependentes da importação de fontes de energia que permitam manter os níveis de conforto e de qualidade de vida a que a sua população se habituou. Em virtude do tempo de vida limitado das reservas de petróleo, principal combust...
