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.

Hydrotreatment process

Process for the catalytic hydrotreating of a hydrocarbon feed stock containing silicon compounds comprising the steps of

Process for the catalytic hydrotreating of silicon containing hydrocarbon feed stock

Downflow catalytic reactor having a plurality of catalyst beds in which a mixture of gas and liquid are passed, the region in between subsequent catalyst beds being provided with a distributor system for the distribution and mixing of gas and liquid prior to contact with a subsequent catalyst bed, said region comprising:

Distributor system for downflow reactors

Liquid-vapour distribution device for use in two-phase concurrent down-flow vessels, having a level, horizontal tray being perforated with holes, each perforation through the horizontal tray being fitted with a vapour lift tube, the vapour lift tube including at least one elongated up-flow leg and one down-flow leg creating at least one up-flow zone and a down-flow zone between the up-flow zone and down-flow zone, and a bluff body being arranged within the transition zone and/or in a region of the upflow or down-flow zone adjacent to the transition zone of the vapour lift tube.

Vapour-liquid distribution tray

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.
