Abstract: A process for hydrodesulfurizing an olefinic naphtha feedstock while retaining a substantial amount of the olefins, which feedstock has a T95 boiling point below 250° C. and contains at least 50 ppmw of organically bound sulfur and from 5% to 60% olefins, the process including hydrodesulfurizing the feedstock in a sulfur removal stage in the presence of a gas including hydrogen and a hydrodesulfurization catalyst, at hydrodesulfurization reaction conditions, to convert at least 60% of the organically bound sulfur to hydrogen sulfide and to produce a desulfurized product stream wherein the gas to oil ratio and the pressure are configured for the selectivity slope, (% HDS−% OSAT)/(% OSAT*(100−% HDS)), to be above 0.55, and to provide a lower octane loss at all severities above 60% HDS, compared to compared to all prior reported processes with similar conversion of organic sulfur with a lower gas to oil ratio, as measured by the selectivity slope.

Abstract: The invention relates to a structured catalyst for catalyzing steam methane reforming reaction in a given temperature range T upon bringing a hydrocarbon feed gas into contact with the structured catalyst. The structured catalyst comprises a macroscopic structure, which comprises an electrically conductive material and supports a ceramic coating. The macroscopic structure has been manufactured by 3D printing or extrusion and subsequent sintering, wherein the macroscopic structure and the ceramic coating have been sintered in an oxidizing atmosphere in order to form chemical bonds between the ceramic coating and the macroscopic structure. The ceramic coating supports catalytically active material arranged to catalyze the steam methane reforming reaction, wherein the macroscopic structure is arranged to conduct an electrical current to supply an energy flux to the steam methane reforming reaction. The invention moreover relates to methods of manufacturing the structured catalyst and a system using the structured catalyst.
