Key words: supported «nickel on kieselguhr» catalyst, regeneration, supercritical carbon dioxide
The nature of deactivating deposits forming on the supported «nickel on kiеselguhr» catalyst in the course of hydration of unsaturated compounds is analyzed. The possibility of regeneration of the catalyst using pure and polar additive (3 wt. % methanol) modified supercritical carbon dioxide (SC-CO2) is investigated at 70 and 150 °C in the pressure range 10÷30 MPa. The kinetic features of the catalyst regeneration with SC-CO2 is studied.
