The oxidation of methane, ethane, propane, and n-butane has been studied over CeO2 and Ce0.8Sm0.2Ox (SDC) catalysts. The rates for methane and ethane were found to be indistinguishable over the two catalysts, while the rates for propane and n-butane were much higher on ceria compared to SDC. The difference between n-butane oxidation over ceria and SDC is shown to result from a low-temperature r...

Nanocrystalline thin films of the alkane skeletal isomerisation catalyst sulfated zirconia were successfully deposited on a silicon substrate in order to allow the application of surface science techniques. Thermal treatment of the films was optimised to chemically mimic the powder preparation process, resulting in films possessing the essential features (including tetragonal phase, nanocrystal...

Canadian Biosystems Engineering/Le génie des biosystèmes au Canada. 52: 4.9 4.14. Accurate measurement of embryonic respiration can be used to determine the viability of the chicken embryo and the chick upon hatching. This measurement is based on both t...

X $EVWUDFW In this study the partial oxidation of Q-butane to maleic anhydride (MA) in a solid electrolyte membrane reactor (SEMR) was investigated experimentally. The electrical conductivity of solid electrolyte membrane materials and vanadium phosphorus oxide (VPO) catalyst was investigated with 2-probe impedance spectroscopy. 13% yttria stabilized zirconia was selected as the solid electroly...

A field study was performed to evaluate the potential for in-situ aerobic cometabolism of 1,1,1-trichloroethane (1,1,1-TCA) through bioaugmentation with a butane enrichment culture containing predominantly two Rhodococcus sp. strains named 179BP and 183BP that could cometabolize 1,1,1-TCA and 1,1-dicholoroethene (1,1-DCE). Batch tests indicated that 1,1-DCE was more rapidly transformed than 1,1...

Vanadyl pyrophosphate (VPP) is the active catalytic phase that converts n-butane to maleic anhydride in fixed beds, fluidized and DuPont’s circulating bed (CFB). The original CFB concept was based on Mars van-Krevelen reaction mechanism which solid lattice contributes all of oxygen partially oxidize n-butane. However, maintain high activity selectivity requires surface oxidized; thus, DuPont co...
