Abstract

The effect of pressure on the rates of product formation in n-heptane conversion on Pt/Al2O3 has been studied at 490 °C over the pressure range of 10–50 atm. It has been shown that the rate of isomerization is practically independent of pressure, and the dependence of the rates of dehydrocyclization and hydrocracking on pressure is described by simple kinetic equations. The reaction order of dehydrocyclization with respect to hydrogen tends to −2.0 at high pressures.

Abstract

Исследовано влияние давления на скорости отдельных направлений превращения н-гептана на алюмоплатиновых катализаторах в интервале давлений 10–50 ат и при температуре 490°C. Показано, что скорость изомеризации практически не зависит от давления, зависимость скоростей реакций дегидроциклизации и гидрокрекинга от давления описывается достаточно простыми уравнениями. Порядок реакции дегидроциклизации по водороду при повышении давления в пределе стремится к−2,0.
