Abstract: A process and hydrodeoxygenation catalyst for producing high-quality diesel and naphtha fuels from a feedstock that contains oxygen containing components derived from renewable organic material in which the hydrodeoxygenation catalyst is a supported Mo catalyst and in which the support has a bimodal porous structure. The hydrodeoxygenation catalyst has a Mo content of 0.1 to 20 wt %. The support is alumina, silica, titania or combinations thereof, and the support has a bimodal porous structure with pores with a diameter larger than 50 nm that constitute at least 2 vol % of the total pore volume.

Abstract: A process for the hydrotreating of fuels with co-production of hydrogen during operation of the process, which enables i.e. reduced need of make-up hydrogen in the hydrotreating stage. The hydrocarbon fuel introduced to the hydrotreatment stage is a fuel containing renewable organic material which generates carbon monoxide during operation of the process. The carbon monoxide is then converted to hydrogen in the recycle loop by a water gas shift stage.

Abstract: A process for preparation of a paraffin isomerization catalyst comprising a mixture of a Group IVB metal oxide, a Group VIB metal oxide, a Group IIIA metal oxide and a Group VIII metal. The process includes the steps of: a) contacting a hydroxide of the Group IVB metal with an aqueous solution of an oxyanion of the Group VIB metal to provide a mixture, (b) drying the mixture to provide a dry powder, (c) kneading the powder with a Group IIIA hydroxide gel and a polymeric cellulose ether compound to form a paste, (d) shaping the paste to form a shaped material, (e) calcining the shaped material to form a calcined material, (f) impregnating the calcined material with an aqueous solution of a Group VIII metal salt to provide the catalyst, and (g) calcining the catalyst.

Abstract: Process for the catalytic hydrotreating of a hydrocarbon feed stock containing silicon compounds comprising the steps of contacting the feed stock in presence of hydrogen with a first hydrotreating catalyst being arranged in at least two reactors being connected in series at an outlet temperature of up to 410° C. to reduce content of the silicon compounds in the feed stock; cooling of the feed stock such treated to a temperature of between 280° and 350° C.; and contacting the cooled feed stock with a second hydrotreating catalyst at conditions being effective in reduction of sulphur compound and nitrogen compound concentration.

Abstract: Process for the removal of coloured compounds in a hydrocarbon feedstock comprising the steps of hydrotreating the feedstock in presence of a first hydrotreating catalyst under conditions being effective in hydrogenation of hydrogenable compounds being present in the feedstock and hydrotreating an effluent from the first hydrotreating step in a second catalytic hydrotreating step being carried out in a second hydrotreating reactor at hydrotreating conditions, wherein the effluent from the first hydrotreating step is separated into a gas phase and a mixed gas and liquid phase prior to the second hydrotreating step, and the mixed phase is hydrotreated in the second hydrotreating step without further addition of hydrogen.

Abstract: Described herein is a combined process for improved hydrotreating of diesel fuels, in which the feed to be hydrotreated is pretreated with a selective adsorbent prior to the hydrotreating step to remove polar materials, especially nitrogen containing compounds (N-compounds). The selective adsorption process can employ either liquid or solid adsorbents. After contact of the adsorbent with the diesel fuel feed, the adsorbent containing undesired polar compounds is separated from the diesel fuel. The separated adsorbent is then subjected to a two step procedure for regeneration.
