Abstract: A nickel catalyst comprising 0.1 to 12.5 wt. % of at least one structural promoter, selected from the group of oxides of metals and metalloids and combinations thereof, and 87.5 to 99.9 wt. % nickel, calculated on the weight of nickel and the structural promoter together, the catalyst having an nickel surface area, as defined herein, of at least 10 m2/g catalyst and an average pore diameter, as defined herein, of 10 to 60 nm. It has been found that already very small amounts of promoter improves the structure of the catalyst. High amounts still provide a stable, sinter resistant material, but result in a decrease in the pore size to lower levels. Furthermore, properties and sulfur uptake capacity.

Abstract: A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent which selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases which have been coadsorbed with the hydrocarbons. The process is particularly useful in removing hydrocarbons from a hydrogen sulfide-containing stream which is being directed to Claus processing for conversion into elemental sulfur. Useful adsorbents include crystalline titanium silicate molecular sieves containing titania octahedral sites such as ETS-10 and similar materials, as well as high silica aluminosilicate zeolite.

Abstract: A process for catalytically generating a hydrogen-rich gas from a hydrocarbon feed. A stream comprising the hydrocarbon feed, water and air is preheated to a temperature sufficiently high to initiate catalytic partial oxidation of the hydrocarbon feed. The preheated stream is then introduced into an autothermal reactor containing a layered catalyst member at a temperature sufficient to initiate and sustain both catalytic partial oxidation and catalytic steam reforming. At least part of the hydrocarbon feed is catalytically partially oxidized to produce a hydrogen-rich gas comprising hydrogen and carbon oxides and hydrocarbons remaining in the feed are steam reformed to produce further quantities of the hydrogen-rich gas. The layered catalyst member comprises a monolith substrate containing at least one layer of a steam reforming catalyst in contact with at least one layer of a catalytic partial oxidation catalyst.
