摘要: A process plant and a process for production of a hydrocarbon suitable for use as jet fuel from a feedstock being a renewable feedstock or an oxygenate feedstock, including combining the renewable feedstock with an amount of a hydrocracked intermediate product, directing it to contact a material catalytically active in hydrodeoxygenation under hydrodeoxygenation conditions to provide a hydrodeoxygenated intermediate product, fractionating the hydrodeoxygenated intermediate product in at least two fractions including a first fraction of which at least 90% boils below a defined boiling point and a second fraction of which at least 90% boils above the defined boiling point, directing at least an amount of the second fraction to contact a material catalytically active in hydrocracking under hydrocracking conditions to provide the hydrocracked intermediate product, the process being suited for efficiently converting the upper-boiling point of an oxygenate feedstock such as a renewable feedstocks to a lower boiling product.

摘要: 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.
