The applicability of a fiber-optic densitometer for monitoring of the reaction mixture density in the course of heterogeneous catalytic reactions is demonstrated on an example of isobutane alkylation with butene in supercritical conditions at 150 °C and 80 atm. Density measurements are carried out in two points — before and after the fixed bed of the H-USY zeolite catalyst. Temperature and pressure dependencies of density and refraction index of butene-isobutane mixture are revealed.
