this work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for control of so2 and nox emission in an iranian steam power plant. minimum amount of required fuel oil desulphurization was calculated from the limit of so2 emissions of power plants in two different scenarios based on (i) european and (ii) iranian so2 emission standards. based o...
A novel generic method of silica supported catalyst system generation from a fluid state is presented. The technique is based on the combined flow and radiation (such as microwave, thermal or UV) induced co-assembly of the support and catalyst precursors forming nano-reactors, followed by catalyst precursor decomposition. The transformation from the precursor to supported catalyst oxide state c...
The activity of a Te-MgO catalyst prepared by adsorbing Te vapor onto MgO powder was determined by dehydrogenation of indane, 9,10-dihydrophenanthrene, cumene, and p-cymene. The activity of the Te-MgO catalyst was higher than that of the MgO catalyst in most of the cases investigated. The selectivity of the former catalyst was much higher than that of the later in all cases studied. The Te-MgO ...
Ever more active hydrotreating (HDT) catalysts should be developed to meet the growing demand for cleaner fuels. With each novel generation of HDT requirements performance, stability and possibility regeneration become sophisticated. Versatile types organic molecules are applied improve catalysts, activate regenerated catalysts. The additives dispersion phase, degree promotion modify interactio...
