NOVELTY - Integrated process for generation of saturated 3C and higher hydrocarbons from carbon oxide and hydrogen, comprises: (a) feeding a gas feed stream including carbon oxide and hydrogen to a two-stage reaction system comprising a first stage including a carbon oxide conversion catalyst; (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, and the product stream including saturated 3C and higher hydrocarbons.    USE - The process is useful for generating saturated 3C and higher hydrocarbons from carbon oxide and hydrogen.    ADVANTAGE - The process is capable of generating of saturated 3C and higher hydrocarbons with improved conversion rate, selectivity, and/or longer catalyst life.    DETAILED DESCRIPTION - Integrated process for generation of saturated 3C and higher hydrocarbons from carbon oxide and hydrogen, comprises: (a) feeding a gas feed stream including carbon oxide and hydrogen to a two-stage reaction system comprising a first stage including a carbon oxide 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, where at least a portion of the intermediate stream is converted to saturated hydrocarbons; and (c) removing a product stream from the second stage, and the product stream including saturated 3C and higher hydrocarbons, where the second stage is operated at a pressure lower than that of the first stage. An INDEPENDENT CLAIM is included for apparatus for the generation of saturated 3C and higher hydrocarbons from a feed stream including carbon oxide and hydrogen, comprising two-stage reaction system comprising a first stage arranged to receive the feed stream and including a carbon oxide conversion catalyst, a second stage arranged to receive an intermediate product stream from the first stage, where the second stage including a dehydration/hydrogenation catalyst, and the apparatus means for controlling the pressure in the two-stage reaction system such that the pressure in the first stage is greater than the pressure in the second stage.
