“…An energy efficiency of 1.21 MJ/kg H 2 was achieved with a hydrogen yield of 89.9% and a methane conversion of 90.2%. Horng et al 15 assessed the reforming performance of the arc plasma-catalyst hybrid converter in hydrogenrich gas production by partial oxidation reforming of propane. These results serve as good guidelines for setting up parameters when reforming hydrocarbon fuels on-board vehicles.…”

Hybrid dielectric barrier discharge-catalytic steam reforming is proposed here for use in chemically recuperated gas turbines, so as to be compatible with the low-temperature exhaust heat from turbines. Four different types of reactor were designed for comparison, and extensive experiments were performed to evaluate the exhaust heat recovery in terms of effective carbon recovery rate, methane conversion, fuel heating value increase rate, and total enthalpy increase rate. The effect of methane space velocity and reactor wall temperature on methane conversion have been analyzed. The results showed that, for any reactor, there was an optimum methane space velocity for the most heat recovery. With increasing wall temperatures, the parallel synergistic reforming technology induced more methane conversion than the other reactors. Under the same input power, parallel synergistic reactors could recover more exhaust heat than the sum of catalyst-only and plasma-only reactors, with a relative total enthalpy increase as much as three times the sum of the latter two. Moreover, the parallel synergistic reforming technology resulted in a higher relative total enthalpy increase for reformed gas at low temperatures. These results demonstrate that parallel synergistic reforming technology is a promising technology to significantly recover exhaust heat under different working conditions.

“…Under non-catalytic pyrolysis conditions of 750 °C the group reported a high propane conversion of 100 %. The gaseous products were 45 % methane, 25 % hydrogen and 15 % acetylene [20]. Similarly to Solovyev et al [17], Wang et al [18] concluded that C-C bond breakage dominates under the pyrolysis conditions of propane.…”

Non-thermal plasma reforming unit operating at atmospheric pressure has been developed for converting propane to COx free hydrogen. Argon was used to provide additional electrons and photons for higher reaction rates. A series of experiments have been performed for positive corona discharge at 15 mm inter-electrode distance to study the effects discharge power and residence time. A range of each test parameter was covered, namely, the effect of discharge power in the range of 19 – 35 W and residence time of 60 to 303 seconds. The results analysis shows that both, the discharge power and the residence time, have a positive influence on propane conversion, hydrogen selectivity and energy conversion efficiency. Propane conversion and hydrogen selectivity are both highest at the largest discharge power of 35 W and the longest residence time of 303 s

“…O uso do argônio como gás plasmogênico evita a formação de CO 2 no processo e é necessário apenas para iniciar a formação do plasma podendo ser substituído pelo próprio gás a ser degradado. Outro fator importante é que o processo a plasma possibilita a utilização de diferentes fontes de matéria prima, além do gás metano ou butano, como qualquer fonte de hidrocarbonetos ou gases provenientes de gás de aterro (TAO et al, 2008), (CHEN et al, 2008), (HORNG et al, 2009). Assim a produção de hidrogênio como fonte energética e a produção de negro de carbono como insumo industrial se torna atrativa e compensa o gasto energético e operacional do sistema (CHEN et al, 2008), (CHAUBEY et al, 2013).…”

ResumoO gás metano (CH 4 ) é um dos principais gases indutores do efeito estufa. Pesquisas científicas recentes visam minimizar o acúmulo deste gás na atmosfera e desenvolver processos capazes de produzir materiais estáveis com valor agregado. O plasma térmico é uma alternativa promissora para alcançar tais objetivos, pois possibilita a obtenção de H 2 e carbono sólido a partir do CH 4 , sem a formação paralela de subprodutos como CO 2 e NO x . Neste trabalho, o CH 4 foi degradado por plasma térmico visando a produção de hidrogênio (H 2 ) e negro de carbono. A eficiência de degradação do CH 4 , o rendimento do processo e a caracterização do negro de carbono produzido foram estudados. Os melhores resultados obtidos foram no fluxo de 5 L min -1 de CH 4 a porcentagem de degradação e a seletividade para a produção de H 2 chegam a 98,8 % e 48,4 %, respectivamente. Em fluxos menores que 5 L min -1 , o rendimento na produção de H 2 aumenta e chega a 91,9 %. O negro de carbono obtido apresenta estrutura amorfa, características hidrofóbicas e pode ser comercializado como material para compósitos, podendo ainda ser ativado química e/ou fisicamente e utilizado como material adsorvente. Palavras-chave: Plasma térmico. Metano. Hidrogênio. Negro de carbono. AbstractMethane gas (CH 4 ) is the main inducer of the so called greenhouse gases effect. Recent scientific research aims to minimize the accumulation of this gas in the atmosphere and to develop processes capable of producing stable materials with added value. Thermal plasma technology is a promising alternative to these applications, since it allows obtaining H 2 and solid carbon from CH 4 , without the parallel formation of byproducts such as CO 2 and NO x . In this work, CH 4 was degraded by thermal plasma in order to produce hydrogen (H 2 ) and carbon black. The degradation efficiency of CH 4 , selectivity for H 2 production as well as the characterization of carbon black were studied. The best results were obtained in the CH 4 flow rate of 5 L min -1 the degradation percentage and the selectivity for H 2 production reached 98.8 % and 48.4 %, respectively. At flow rates of less than 5 L min -1 the selectivity for H 2 production increases and reaches 91.9 %. The carbon black has obtained amorphous with hydrophobic characteristics and can be marketed to be used in composite material, and can also be activated chemically and/or physically and used as adsorbent material.
