Effect of Cr and Co Promoters Addition on Vanadium Phosphate Catalysts for Mild oxidation of n-Butane

引用

Journal of Natural Gas Chemistry 2006年第2期15卷 144-148页

作者： Yun Hin Taufiq-yap Putra Laboratory for Catalysis and Technology Department of ChemistryFaculty of ScienceUniversiti Putra Malaysia43400 UPM SerdangSelangorMalaysia

In this study, Cr and Co promoted, as well as unpromoted vanadium phosphate （VPo） catalysts were synthesized by the reaction of V2o5 and o-H3Po4 in organic medium followed by calcination in n-butane/air environment at 673 K. The physico-chemical properties and the catalytic behavior were affected by the addition of Cr and Co dopants. H2-TPR was used to investigate the nature of oxidants in the unpromoted and promoted catalysts. The results showed that both the Cr and Co promoters remarkably lowered the temperature of the reduction peak associated with V^5＋. The amount of oxygen species originated from the active phase, V^4＋, removed was significantly increased for Co and Cr-promoted catalysts. Both Cr and Co dopants improve strongly the n-butane conversion without sacrificing the MA selectivity. A good correlation was observed between the amount of oxygen species removed from V^4＋ phase and the activity for n-butane oxidation to maleic anhydride. This suggested that V^4＋-o was the center for the activation of n-butane.

Solubility data of recalcitrant contaminants in cosolvents is essential to determine their potential applications in enhanced soil *** solubilities of phenanthrene,anthracene,fluoranthene and benzo[a]pyrene in ethyl lactate/water and ethanol/water mixtures were measured using equilibrium *** cosolvency powers derived from solubility data were then applied to the model developed from the solvophobic approach to predict the capability of ethyl lactate and ethanol in enhancing the desorption of contaminants from *** ethyl lactate and ethanol cosolvents were shown to be able to enhance the solubilisation of the tested four polycyclic aromatic hydrocarbons by 〉 4 orders of magnitude above the levels obtained with water ***,ethyl lactate demonstrated a greater capacity to enhance PAH solubility than *** cosolvency powers of ethyl lactate/water system obtained from the end-to-end slope （σ） and the end-to-half slope （σ 0.5） of the solubilisation curve were 1.0-1.5 and 2.0-2.9 higher than ethanol/water system *** line with this,ethyl lactate/water was demonstrated to enhance the desorption of contaminants from soil by 20%-37% and 18%-61% higher compared to ethanol/water system in low organic content and high organic content soils respectively,with a 2：1 （V/W） ratio of solution：soil and with cosolvent fraction as low as *** the exception of benzo[a]pyrene,the experimental desorption results agreed fairly with the predicted values,under an applied solution：soil ratio that was enough to hold the capacity of released contaminants.

Abnormal endogenous pain modulation and somatic and visceral hypersensitivity in female patients with irritable bowel syndrome

引用

World Journal of Gastroenterology 2007年第27期13卷 3699-3704页

作者： Clive H Wilder-Smith Joan Robert-yap Brain-Gut Research Group Gastroenterology Group Practice Berne Switzerland Supported by the Brain-Gut Research Group Berne Switzerland

AIM： To investigate the role of endogenous pain modulatory mechanisms in the central sensitization implicated by the visceral hypersensitivity demonstrated in patients with irritable bowel syndrome （IBS）. Dysfunction of modulatory mechanisms would be expected to also result in changes of somatic sensory function. METHoDS： Endogenous pain modulatory mechanisms were assessed using heterotopic stimulation and somatic and visceral sensory testing in IBS. Pain intensities （visual analogue scale, VAS 0-100） during suprathreshold rectal distension with a barostat, cold pressor stimulation of the foot and during both stimuli simultaneously （heterotopic stimulation） were recorded in 40 female patients with IBS and 20 female healthy controls. RESULTS： Rectal hypersensitivity （defined by 95% Cl of controls） was seen in 21 （53%）, somatic hypersensitivity in 22 （55%） and both rectal and somatic hypersensitivity in 14 of these IBS patients. Heterotopic stimulation decreased rectal pain intensity by 6 （-11 to -1） in controls, but increased rectal pain by 2 （-3 to ＋6） in all IBS patients （P 〈 0.05） and by 8 （-2 to ＋19） in IBS patients with somatic and visceral hypersensitivity （P 〈 0.02）. CoNCLUSIoN： A majority of IBS patients had abnormal endogenous pain modulation and somatic hypersensitivity as evidence of central sensitization.
