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 اولSynthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...

ru/al2o3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of rucl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. the samples were characterized by tem, xrd and tpr techniques. the catalytic performance tests were carried out in a fixed-bed micro-reactor under different operating conditions. ethylene g...
متن کاملOptimisation of an Ammonia Synthesis Loop
A Hysys model representing the steady state behaviour of a Haber-Bosch ammonia plant was developed based on a dynamic model and plant data from Norwegian fertiliser company Yara International ASA. The plant model was optimised using matlabs fmincon function with an interior-point method for economical optimisation with the aim to study the performance of different strategies. The Haber-Bosch am...
