HYDROGENATION OF CARBON DIOXIDE TO METHANOL OVER SUPPORTED COPPER/ZINC OXIDE-BASED NANOCATALYST

Methanol synthesis via C02 hydrogenation provides alternative route for methanol
production and attractive option for C02 utilization. The objective of this work is to
synthesize, characterize Cu-ZnO-based nanocatalyst on various supports and study the
performance of the nanocatalyst for methanol production via C02 hydrogenation
reaction. Supported Cu!ZnO-based nanocatalysts have been formulated using
impregnation method. Effects of synthesis parameters such as total metal loading,
Cu:Zn ratio, synthesis pH and type of support on the physicochemical properties and
catalytic performance in C02 hydrogenation to methanol were investigated. The effects
of the alkali promoters such as manganese (Mn), zirconium (Zr), lead (Ph), and niobium
(Nb) in form of single, double, and tri-promoters on the physicochemical properties of
the catalyst have been investigated.
