APPLICATIONS: 

This invention is a novel class of catalysts for production of synthetic methanol from CO2 and hydrogen.

PROBLEMS ADDRESSED:

Global methanol demand is growing as result of increasing demand as a feedstock in polymer production and because of emerging alternative energy applications. CO2 hydrogenation is the standard approach for producing synthetic methanol. However, achieving high selectivity in direct CO2 conversion to methanol under the most desirable reaction conditions is a hurdle to lower cost synthetic methanol production. Conventional catalysts tend to sinter at higher temperatures where the hydrogenation reaction is faster, leading to deactivation. Researchers at the University of Delaware have developed highly selective catalyst compositions for CO2 hydrogenation that can operate at higher temperatures without deactivation.

BENEFITS:

  • High selectivity and stability
  • Relatively inexpensive
  • No undesirable by-products
  • Cleaner plastic manufacturing feedstock

TECHNOLOGY DESCRIPTION:

This invention is a novel class of catalysts that catalyzes the conversion of CO2 to methanol. The catalyst gives higher selectivity compared to conventional catalysts and can be used at higher temperatures without sintering that leads to deactivation.   .

STAGE OF DEVELOPMENT:

Multiple compositions have been demonstrated in laboratory conditions.  Further development for optimization of selectivity and stability at pilot-scale and production levels is required.
