Abstract
A 0.25 % Pt/γ-Al2O3 catalyst was investigated. The sample was tested in modelling of joint conversion of butane and hexane, propane, and heptane with assessing kinetic parameters of the reactions under study. It was found that a decrease in the activation energy by 10.6 kJ/mol and an increase in the rate constant of aromatization by 1.3 times in comparison with hexane conversion was observed at joint conversion of butane and hexane, which leads to an increase in the yield of aromatic hydrocarbons. At the introduction of propane into the reaction medium to heptane, a reverse dependence was detected.
