PHYSICO-CHEMISTRY OF THE PROCESSES OF SULPHATOFORMATION WITH LIME STONES

The object of investigation: the heterogenous system CaCO*003 - CaO - SO*002 - SO*003 - O*002. The chemism of the processes of interaction SO*002 with the products of the calcite decay, the kinetics of the heterogenous reactions has been studied, the detailed description of analytics of the composition and localization of solid phases in the reaction zone has been given. The composition of the arising phases has been determined, the mechanism of the topochemical reactions of the sulphur oxides with calcite at high temperatures has been established. The mathematical model and the computer program, optimizind the phase composition in the multicomponent systems, depending on the conditions, has been developed. The application of the thermogravimetric method of analysis has been shown for the purposes of modeling of the processes of gases sulphur-cleaning. The method of evaluation of the porosity has been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
