Multilevel reactor, its uses, and process for manufacturing hydrogen peroxide

A process of reacting at least two gaseous reactants in the presence of a solid catalyst suspended in a liquid phase, which comprises injecting said gaseous reactants at the bottom of a cylindrical vertical reactor, having a bottom and a top, stirring the gaseous reactants in the liquid phase containing the solid suspended catalyst with a plurality of centrifugal turbines arranged along a vertical agitating shaft oriented on the central axis of said vertical reactor and discharging a gaseous reaction product from the top of said reactor.

A process for preparing an aqueous solution of hydrogen peroxide starting from hydrogen and from oxygen, comprising injecting hydrogen and oxygen into the bottom of a cylindrical vertical reactor having a bottom and a top, containing a liquid phase containing a solid suspended catalyst stirring said hydrogen and oxygen in said liquid phase containing a solid suspended catalyst with a plurality of centrifugal turbines arranged along a vertical agitating shaft oriented on the central axis of said vertical reactor.
