Essay

Deactivation of acidic forms of zeolites in cracking of hydrocarbons, dynamics of coke-forming. Deactivation of zeolitic catalyst in heterogenic-catalytic carbonium-ion hydrocarbon conversion. Ionic exchange, low temperature absorption of nitrogen, ІR- and EPR-spectroscopy. It has been proposed the high precise express method for catalyst coke studying, which using permitted to reveal the oscillatory catalyst deactivation on the initial stage of coking, dynamics of coke oxidation and of H/C ratio change for burning coke. The coke nature depending on catalyst acidity, porosity and nature of deactivation agents has been determined. The found peculiarities have been connected with coke and substrate competition over catalyst surface, different reaction activity of hydrogen-rich and hydrogen-poor coke as well as with peculiarities of the pore structure of the catalysts. Sphere of use - petrochemistry.
