Hydroformylation of 1-Hexene over Rh/Nano-Oxide Catalysts
The effect of nanostructured supports on the activity of Rh catalysts was studied by comparing the catalytic performance of nanoand bulk-oxide supported Rh/ZnO, Rh/SiO2 and Rh/TiO2 systems in 1-hexene hydroformylation. The highest activity with 100% total conversion and 96% yield of aldehydes was obtained with the Rh/nano-ZnO catalyst. The Rh/nano-ZnO catalyst was found to be more stable and ac...
متن کاملNon-oxidative conversion of methane to aromatics over modified zeolite catalysts by transitional metals
The activity of different transitional metals over modified H-ZSM-5 catalysts for methane conversion to aromatics was compared. The first group of catalysts was Mo-impregnated H-ZSM-5 zeolites with 1, 3 and 6 wt% of Mo. The second group was M(3 wt%)- impregnated H-ZSM-5 (M: Ag, Cd, Cr, Mo, Zn and Mn). The catalytic activity of the first group was investigated at 600, 700 and 800 °C and gas hour...
متن کاملOptimization of formic acid hydrolysis of corn cob in xylose production
−Dilute acid pretreatment of lignocellulosic material is one of the significant steps in a biorefinery. We used response surface methodology to determine the important factors of formic acid concentration (2%-6% wt%), treatment time (30-150 min), reaction temperature (120-160 oC), and liquid to solid ratio (3-11 mL/g) on dilute acid hydrolysis of corn cob to produce xylose. A xylose yield of 81...

متن کاملFormic Acid Oxidation over Hierarchical Porous Carbon Containing PtPd Catalysts
The use of high surface monolithic carbon as support for catalysts offers important advantage, such as elimination of the ohmic drop originated in the interparticle contact and improved mass transport by ad-hoc pore design. Moreover, the approach discussed here has the advantage that it allows the synthesis of materials having a multimodal porous size distribution, with each pore size contribut...
