Some possible elementary reactions are not included in the classical mathematical models of thermal decomposition. For example, we can assume that in the thermal decompositions of simple carbonates a proportion of the O2− ions produced on the reaction interface can migrate into the interior of the reactant phase, since at this temperature there is some probability of CO2 exchange between an O2− and a neighbouring CO32− ion. A similar diffusion-type process can be assumed in a wide class of decomposition reactions. The present state of computer science makes it possible to show by mathematical modelling how this migration influences the TG curves of the simplest contracting-sphere-type reactions. The resulting extended contracting-sphere model can provide the induction and the acceleration period of the TG curves.
Progress is reviewed in the authors' works on actinide extraction equilibria (including activity coefficient evaluation from extraction data) and their mathematical modelling (including Tc influence on Pu/U separation).
A mathematical model is suggested for the approximation of the monoenergetic gamma-ray spectra obtained by a Ge(Li) detector.
Some features of the instrumentation monoline spectra in the energy range upto 2 MeV are considered in detail. Computer program
“APPROXIMATSIYA” is described. The program allows to determine the parameters of the mathematical model with the purpose to
construct a making up standard spectrum library. The results of the monoline spectrum processing are discussed.
Mathematical modeling of toluene oxidation under unsteady state catalyst created by forced oscillations of concentration of
toluene in the reactor inlet was carried out. It is shown that, under periodic reactor operation, the benzaldehyde yield was
up to several times higher than the steady state value. This was explained by the participation of different oxygen species
in the partial and total oxidation on the catalyst surface.
