Hydrogenation of Carbon Monoxide on Composite Catalytic Systems Derived from Nickel and Polyvinyl Alcohol.

This article considers the catalytic and physicochemical properties of composite materials obtained by the heat treatment of nickel nitrate immobilized on polyvinyl alcohol (PVA). The effects of the composite formation temperature on the phase composition of the metal-containing particles and their size were studied. The composite material obtained was found to be an active catalyst for the hydrogenation of carbon monoxide without a pre-activation step. The following synthesis parameters were achieved: 29% carbon monoxide conversion under conditions for catalytic hydrogenation and 28 g/m3 methane yield. Hypotheses were offered concerning the effect of particle size on the activity of the synthesized composite and an effect of the volume velocity on the carbon monoxide hydrogenation process parameters was demonstrated.
