Abstract: A composite sorbent is formed which is the reaction product of a solid alkali metal carbonate, rehydratable alumina and water or an aqueous solution of a metal salt. The reaction between the components occurs while forming particulates followed by curing and activation at high temperatures. The alkali metal in the sorbent exhibits a highly reactive and accessible state that is very favorable for various sorption applications. The sorbent is especially useful for removal of HCl and other acid contaminants from gas and liquid hydrocarbon streams at high temperatures.

Abstract: Apparatus and processes for the generation of hydrogen from hydrocarbon feeds are provided in which organosulfur compound is removed from the feed. The apparatus and processes are particularly advantageous as smaller scale hydrogen generators including those generators intended for residential use to produce hydrogen for fuel cells to produce electricity. In the processes and apparatus, the feed is contacted with solid sorbent to remove organosulfur compound.

Abstract: By the present invention, a process is provided to use a modified clinoptilolite adsorbent suitable for the separation of carbon monoxide from hydrogen and hydrocarbon streams without adsorbing hydrocarbons such as paraffins and olefins. In typical applications in platforming units within refineries, these hydrogen streams contain from 5 to 20 parts per million of carbon monoxide. In other applications the level of carbon monoxide may be higher. The separation of carbon monoxide from the hydrogen stream is achieved by using a clinoptilolite molecular sieve that has been ion-exchanged with at least one cation selected from lithium, sodium, potassium, calcium, barium, and magnesium.
