Acid–base cooperativity in condensation reactions with functionalized mesop…
Abstract. The Knoevenagel condensation of benzaldehyde and ethyl cyanoacetate was used to test the acid–base cooperativity of SBA-15 mesoporous silica co-condensed with aminopropyl groups as well as silica cocondensed with dihydroimidazole groups. Surface silanols were capped with trimethylsilyl groups using hexamethyldisilazane to determine the effects of the silanol groups on catalytic …

Esterification of biomass pyrolysis model acids over sulfonic acid-functional…
Abstract. Esterification of acetic acid with methanol, which was used as amodel reaction in the stabilization of biooil, was tested over propylsulfonic acid-functionalized SBA-15 materials. Due to the significant amount of water content in bio-oil, the water tolerance properties of the materials were also investigated in detail. The results showed that the functionalized mesoporous materials…

Stability and phase transitions of potassium-promoted iron oxide in various g…
Abstract. Potassium-promoted iron oxide dehydrogenation catalysts are the primary catalysts used for producing styrene. In this process, a large amount of steam is used and for economic reasons it is desirable to be able to operate at lower steam/ethylbenzene molar ratios without creating severe short-term deactivation. To address this issue, it is essential to understand how the catalyst d…

Development of a Novel Combined Catalyst and Sorbent for Hydrocarbon Reforming
A combined catalyst and sorbent was prepared and utilized for steam reforming methane and propane in laboratory-scale systems. The material was prepared in the form of small spherical pellets having a layered structure such that each pellet consisted of a highly reactive lime or dolime core enclosed within a porous but strong protective shell made of alumina in which a nickel catalyst was l…

A Combined Catalyst and Sorbent for Enhancing Hydrogen Production from Coal o…
Future large-scale production of H2 for use as a clean fuel will likely depend upon gasifying coal or biomass followed by steam reforming the resulting gas mixture and separating the CO2 byproduct. The process of steam reforming and CO2 separation can be greatly simplified by utilizing a new material that combines a reforming catalyst with a sorbent for CO2. Such a material was prepared in t…
