Abstract
Official abstract text for this publication.
The invention relates to a process of making a syngas mixture containing hydrogen, carbon monoxide and carbon dioxide, comprising a step of contacting a gaseous feed mixture containing carbon dioxide and hydrogen with a catalyst, which catalyst substantially consists of Mn oxide and an oxide of at least one member selected from the group consisting of Cr, Ni, La, Ce, W, and Pt. This process enables hydrogenation of carbon dioxide into carbon monoxide with high selectivity, and good catalyst stability over time and under variations in processing conditions. The process can be applied separately, but can also be integrated with other processes, both up-stream and/or down-stream; like methane reforming or other synthesis processes for making products like alkanes, aldehydes, or alcohols.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process of making a syngas mixture containing hydrogen, carbon monoxide, and carbon dioxide, comprising contacting a gaseous feed mixture containing carbon dioxide and hydrogen with a catalyst consisting essentially of oxides of Mn and La and optionally an oxide of at least one member selected from the group consisting of Cr, Ni, Ce, W, and Pt, to form the carbon monoxide. 2. The process according to claim 1 , wherein the catalyst…
