摘要
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, wherein the catalyst substantially consists of chromia/alumina. 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 combined with other processes, for example up-stream with other synthesis processes for making products like aliphatic oxygenates, olefins or aromatics.
