Cobalt-palladium catalysts for the hydrogenation of carbon monoxide are being developed by scientists at the Institute of Catalysis

In recent years, oil reserves have been steadily depleting, and oil is a major source of fuel production. Research into alternative energy sources is therefore becoming increasingly important. An alternative to oil is synthesis gas (mixtures of carbon monoxide-CO and hydrogen-H2). It is a raw material for the production of diesel fuel, lubricants, valuable chemicals, etc. The reaction that takes place is hydrogenation of carbon monoxide. It is extremely important for environmental protection that this production process does not lead to pollution. Cobalt and cobalt-palladium catalysts facilitate this process. […]
