KINETIC MODEL OF HYDROGENATION PYREN

Abstract

The hydrocarbon feedstock consists of condensed aromatic hydrocarbons and other high-molecular compounds are a complex mixture of organic and mineral substances. In such systems it is quite difficult to describe the mechanism of the process of the activity and selectivity of selected catalysts. Model compounds (anthracene, phenanthrene, pyrene, naphthalene, and others.) facilitate the process of learning, depending on the reactivity of the chemical structure of substances as the organic fragments may represent a primary weight of coal tar and its fractions. The results of the hydrogenation polyaromatic hydrocarbon compound, and the calculations of kinetic and thermodynamic parameters of the process. The method of equilibrium-kinetic analysis allows you to link the equilibrium and kinetic characteristics and additional information from the usual array of experimental data, thus to intensify chemical research. Defined and calculated the forward and reverse constant velocity, the equilibrium constant, activation energy, and the thermal effects of the hydrogenation reaction pyrenein the presence of iron-containing catalyst in the temperature range 623-698 K, with an initial hydrogen pressure of 4MPa.
