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.
