Abstract: An integrated process for the generation of saturated C3 and higher hydrocarbons from carbon oxide(s) and hydrogen, includes the steps of: (a) feeding a gas feed stream including carbon oxide(s) and hydrogen to a two-stage reaction system comprising a first stage including a carbon oxide(s) conversion catalyst, where the feed stream is converted in the first stage to form an intermediate product stream, (b) feeding the intermediate product stream to a second stage including a dehydration/hydrogenation catalyst and (c) removing a product stream from the second stage, the product stream including saturated C3 and higher hydrocarbons. The two-stage reaction system could exhibit a high activity and selectivity to C3 and higher hydrocarbons, and the two stage reactions may be operated in different reaction conditions.
