The use of pelletized feedstock in an enzyme-based “biorefinery” would benefit from economies of scale and be capable of utilizing a greater variety of biomass feedstock types. Ground poplar samples were treated using five steam pretreatment regimes including auto-hydrolysis, SO2 catalysis, deacetylation as well as both acidic and neutral sulfonation, followed by being dried and pelletized to form...
Mineral transformation and soot formation are the two governing mechanisms for fine particle formation in the early stage of coal combustion. The interaction between the evaporative alkali species and soot, which can have significant effect on fine particle formation, however, is not fully understood. To investigate the interaction between Na and soot in the early stage of coal combustion, we characterized...
A novel porous copper fiber sintered felt (PCFSF) as catalyst support is fabricated to construct the methanol steam reforming microreactor for hydrogen production. In this study, the heat and mass transfer properties of PCFSF with different porosities is experimentally investigated. The results show that the PCFSF with different porosities exhibits good uniform heat transfer. The thermal conductivity...
