Summary: The influence of reaction parameters, mode of catalyst
preparation and pretreatment, as well as chemical composition and
transport resistance on the catalyst activity, selectivity and
deactivation will be examined. The kinetic experiments, activity test
and poisoning experiments will be carried out in differential and integral
laboratory reactors. Mathematical models for process simulation based
on the kinetics and mechanisms of the catalytic poisoning reactions will
Research goals: On the eve of the 21st century, catalytic
technologies will gradually become important, not only for chemical or
petrochemical industry, but also for other industries, where they are not
so widely applied today. Since catalysts make it possible to
considerably reduce production costs and, as a rule, improve quality of
the products,catalyst study and production are rapidly developing.
Chemical composition alone is not a sufficient quide for predicting the
activity of a catalyst. In many cases the physical characteristics of the
catalyst, such as the surface area,particle size, pore size and crystal
structure, determine its activity and selectivity for specific reaction.
They have also been considered to improve the life time of catalyst, i.e.
to prevent its deactivation. Studying chemical and physical
characteristics of commercial and newly prepared catalysts, kinetics and
mechanisms of the chemical and deactivating processes, effects of the
transport resistance on the reaction and deactivatio rate etc. will
identify the catalyst design variables in order to obtain more active,
selective and stabile catalysts. Other information about the project.
