a study of the kinetic analysis of total lead from spent car battery ash by hydrochloric acidleaching has been examined. the physico-chemical analysis of the ash powder was carried outby the inductively coupled plasma-mass spectrometry (icp-ms) and x–ray diffraction (xrd).the effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...

a mathematical model for commercial naphtha catalytic reformer of tehran refinery was developed. this model includes three sequencing fixed beds of pt/al2o3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of c6 to c9 hydrocarbons. the reaction network consisted dehydrogenation, hydrogenation...

The present paper illustrates an innovative steel processing route developed by employing hydrogen direct reduced pellets and open slag bath furnace. the reduction reactor as reductant on industrial scale. solution allows for production of from blast furnace transformed in reactor. are then melted furnaces, allowing carburization further refining. proposed is clean decarbonization industry. kin...

In this paper, the applicability of the entropy method for the trend towards equilibrium for reaction-diffusion systems arising from first order chemical reaction networks is studied. In particular, we present a suitable entropy structure for weakly reversible reaction networks without detail balance condition. We show by deriving an entropy-entropy dissipation estimate that for any weakly reve...

The report presents results of development of an accurate, physics-based model of vibrational androtational energy transfer in three-dimensional collisions of rotating diatomic molecules, applicable over awide range of collision energies and vibrational / rotational quantum numbers, and results of detailedkinetic modeling studies of state-to-state molecular energy transfer processes...
