Abstract
A process for producing methanol includes combining a hydrogenation catalyst, hydrogen, and CO2 with a condensed phase solution comprising an amine under conditions effective to form methanol and water. A process for coproduction of methanol and a glycol includes combining an epoxide, a hydrogenation catalyst, hydrogen, and CO2 with a condensed phase solution comprising an amine under conditions effective to form methanol and a glycol.
Claims20
A process, comprising:
- producing methanol and a glycol by combining an epoxide, a hydrogenation catalyst, hydrogen, and CO2 with a condensed phase comprising an amine under conditions effective to provide a reaction between the epoxide, hydrogen, and CO2 to form methanol and the glycol, wherein at least 10 mol % of the epoxide is consumed in the reaction.
A process, comprising:
- producing methanol by combining a hydrogenation catalyst, hydrogen, and CO2 with a condensed phase comprising an amine under conditions effective to provide a reaction between the hydrogen and CO2 to form methanol and water, wherein at least 10 mol % of the CO2 is consumed in the reaction;
- separating the methanol and water from the amine;
- and
- separating the methanol and water.
