Abstract
The kinetics of adsorption of dewaxed hydrocreating oil was studied using curves of change in the ratio of the optical density of dewaxed hydrocreating oil to the time t (Dt) and the equilibrium value (De), the intensity of loss of sorption capacity of granular montmorillonite clay activated by hydrochloric acid or the degree of its activation during oxidative adsorption purification of dewaxed hydrocreating oil. The process of oxidative-adsorption oil purification was carried out by percolation in a vertical cylindrical adsorber at a volumetric flow rate of the purified oil through a clay layer equal to 0.5 h-1. The depth of oil purification was determined by a change in the optical density of the purified oil at a constant wavelength of 400 nm. An attempt has been made to study the kinetics of only the stage of oxidation-adsorption purification of hydrocracking oil using a kinetic model of the pseudo-first order and to estimate the activation energy of this stage in the studied temperature range. It was found that the activation energy of the oxidation-adsorption stage of hydrocracking oil purification is 9.15 kJ/mol.
