Biomass Gasification with Air in Fluidized Bed:  Reforming of the Gas Composition with Commercial Steam Reforming Catalysts

Abstract: Four commercial catalysts for steam reforming of higher hydrocarbons (naphthas) and three for steam reforming of light hydrocarbons are tested for hot gas clean up and upgrading in biomass gasification with air in fluidized bed. The catalysts used originate from four manufacturers:  BASF AG, ICI-Katalco, Haldor Topsoe a/s, and United Catalysts Inc. The work is performed in a small pilot plant (1−2 kg of biomass fed/h) with three reactors in series:  gasifier, guard bed of dolomite, and full flow catalytic bed.… Show more

“…For each input speed, the air flow is adjusted so λ is maintained between 0.2 and 0.3, values that are suitable in the literature [18]. Results are shown in Figure 7, together with the more detailed Tables S9-S10.…”

“…9 Esse esquema permite uma maior vida útil do catalisador de reforma, diminuindo a desativação através do coqueamento e do envenenamento por compostos de enxofre e cloro. 78 Exemplificando, a literatura relata que a conversão de alcatrão empregando dolomita em leito de guarda foi igual a 95%, e a conversão em reator de reforma, com catalisadores comerciais a base de Ni, foi superior a 98%.…”

“…34,35 Resultados publicados evidenciaram que os catalisadores usados para reforma a vapor de nafta foram mais ativos que os catalisadores comerciais empregados para a reforma de gás natural. 9 Deve-se destacar que a maioria dos estudos apresentados não emprega injeção de vapor no reator de reforma, já que aproveita o vapor d'água presente na corrente produzida na gaseificação. A razão disto é que a quantidade de H 2 O presente no gás produzido na gaseificação é da ordem de 40-55 %vol quando o agente gaseificante é uma mistura de oxigênio e vapor; e de 10-22 %vol quando se emprega ar atmosférico.…”

“…In practice, it is difficult to reach equilibrium conditions for solid carbon conversion at gasification temperatures below 1000ºC, which is the case with fluidized bed reactors. A composition of a producer gas that is closer to equilibrium one can be obtained using either in-bed catalyst or a secondary catalytic bed reactor (Asadullah et al, 2003;Corella et al, 1998;Kurkela et al, 2009). Gil et al (1999) examined the results of different experimental studies of pine chips gasification in bubbling fluidized silica sand bed using air, pure steam and steam-O 2 mixtures as gasification agents.…”
