Abstract
Abstract Researches of catalysts Pt/WO 3 /ZrO 2 (Pt content is 1 wt.%) at varying WO 3 concentrations (10-35% wt.) are carried out in the isomerization reaction of n-heptane, under the following conditions: temperature range is 140-220°C, pressure is 1.5 MPa, the ratio H 2 /n-heptane is 3 (mol.), heptane volume velocity is 1h-1. X-ray analysis, N 2 adsorption-desorption, infrared spectroscopy, temperature-programmed desorption of ammonia are used to characterize the physical and chemical properties of the prepared catalysts, atomic emission spectrometry with inductively coupled plasma is for WO 3 analysis. Maximum catalysts activity and selectivity in the isomerization reaction of n-heptane is obtained at the reaction temperature of 170°C on the catalyst with a content of 25% wt WO 3 .: conversion of n-heptane is 84%, the selectivity to the heptane isomers sum is 71.9%, dimethyl and trimethyl heptane isomers yield is 22.8% wt.
