Carbon dioxide hydrogenation reaction
Thread Content
The carbon dioxide hydrogenation reaction takes place on Ni-based catalysts; what are the main products? Could everyone please help me answer this? Thank you!
It might be methanol, but currently copper-based catalysts are mostly used for methanol.
It seems nothing can be obtained; the catalyst doesn’t work. It was possible to get things like ethylene, methanol, methane, and so on
Hydrogenation of carbon dioxide – I don’t understand it; please advise someone knowledgeable!
CO+H2O=CO2+H2+Q
It is the synthesis of methanol from CO and H2; in this process, CO2 is used for other purposes, such as being released into the atmosphere or processed into food-grade CO2. If it could be utilized, I think people would have done so already
Methanol can be synthesized from CO2 + H2 over a copper catalyst.
Methane can be obtained under suitable conditions, and the methanation catalysts used in industry are also Ni.
The hydrogenation of carbon dioxide yields carbon monoxide and water in shift catalysts (category 3 catalysts); it produces methanol and water in copper-based synthesis catalysts; and it generates methane in nickel-based alkylation catalysts. Carbon dioxide hydrogenation in iron-cobalt-based synthesis catalysts can yield oils, higher alkanes, waxes, and water.
It’s unlikely to yield any product; methanol should not be produced
