Abstract: The major focus of our research at NSF-CREST Bioenergy Center is to develop novel catalysts for CO2-enriched syngas conversion into liquid fuels and hydrogen production for fuel cell applications. One main objective is to develop robust and stable catalysts for Fischer-Tropsch (F-T) synthesis. To investigate the role of support, the Si-microchannels were coated with titania sol-gel containing Ru, Co, Fe catalysts. The stability and reactivity are observed in the order of 12%Ru-TiO2 >> 12%Fe-TiO2 > 12%Co-TiO2 1; this is in contrast to our F-T studies with SiO2 sol-gel. The phase of the TiO2 support plays a significant role on CO conversion and formation of higher alkanes.1 To avoid different issues with Si-microreactor, that breaks easily, we have extended our F-T synthesis in a 3-D printed Stainless Steel microreactor that can also be used for studies at higher pressure. Our current F-T synthesis using bimetallic Fe-Co, Co-Ru,Co-Ni-MCM-413 and the F-T kinetics of bimetallic Ru-Co catalyst supported by different mesoporous silica will be presented.2 Our research at the Bioenergy Center also involves catalyst development for H2 production from bio-derived alcohols such as methanol and glycerol. Previous studies on steam reforming of methanol with different metals and MCM-41 and TiO2-supports have shown that the interaction between metal and the support plays a profound role on H2 production and its selectivity.3 In contrast to methanol, steam reforming of glycerol at high temperature is quite challenging. Results from our studies using MCM-41 and SBA-15 supports in the presence of CeO2O2, TiO2 and MgO will be presented.
