comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولCatalytic Hydrotreatment of Light Distillates Obtained from Bio-Oil for Use in Oxygenated Liquid Fuels
Bio-oil can be fractionated into three parts according to their boiling points. This research reported that light distillates could be converted into oxygenated liquid fuels through a two-stage hydrotreatment approach, using a Pd/C catalyst. The main goal of the first hydrotreatment stage was to stabilize the high active components, which contained carbon–carbon double bonds and aldehyde groups...
متن کاملHydrotreatment of Heavy Oil from Coal Liquefaction on Sulfided Ni-W Catalysts
Derivados de óleo pesado (temperatura de destilação: 320-340 C), obtidos a partir do processo de liquefação direta do carvão, usando carvão Shengli foram tratados com hidrogênio usando catalisadores sulfetados Ni–Mo/Al2O3, Ni–W/Al2O3 e Ni–W/SiO2 respectivamente. Os catalisadores sulfetados foram caracterizados por BET, XRD, H2–TPR e NH3–TPD, respectivamente. As avaliações das propriedades de hi...
متن کاملGeochemical Modeling with the Use of Vertical and Horizontal Relative Concentrations of Oil Compounds for the Heavy Oil Fields
The purpose of this study is the detection of lateral and vertical gradients of relative concentrations of compounds presented in oil. In addition, the detection allows us to assess potential drainage zones in a reservoir during the reservoir production by steam injection. In this paper, a new method for monitoring of steam chamber development in a 2D model was created and tested. The methodol...
