Quasiisothermal degradation kinetics of tetrapropylammonium cations in silicalite-1 matrices
Original language description
The present work deals with the kinetics of template removal investigated via thermogravimetric measurements both in the flow of non-oxidative and oxidative agent. Apart from linear temperature programs, quasiisothermal conditions were used which consisted in keeping the sample at the temperature of measurement Tmax. A simple kinetic model was formulated which involves the effect of mobilization reaction, rate of mass transfer from crystals to intercrystalline space, intercrystalline diffusion and the rate of mass transfer from the layer of crystals into the main stream of template removing agent. The model qualitatively appreciates all the principal features of template removal procces including the effect of the percolation
