Abstract: A process, a process plant and equipment for conversion of a feedstock rich in oxygenates to a hydrocarbon including directing the feedstock in combination with a recycle gas stream to a hydroprocessing step, to provide a two-phase hydroprocessed process stream including at least hydrogen, methane and hydrocarbons, combining a methane lean stream of hydrocarbons being liquid at ambient temperature, with a methane donor stream being either (i) the two-phase hydroprocessed process stream including methane or (ii) a gaseous stream derived from the two-phase hydroprocessed process stream by phase separation, to provide a multiple-phase combined stream, separating the multiple-phase combined stream into at least a hydrogen rich gas stream and a rich liquid hydrocarbon stream, in a desorption step desorbing an amount of methane from the rich liquid hydrocarbon stream, to provide a methane rich gas phase and a liquid product stream of hydrocarbons.

Abstract: A broad aspect of the disclosure relates to a process for hydroprocessing of a hydrocarbonaceous feedstock stream comprising the steps of



directing said hydrocarbonaceous feedstock stream to contact a material catalytically active in hydroprocessing thus providing a hydroprocessed stream
separating said hydroprocessed stream in a purified hydrocarbon stream, sour water and a separation off-gas,
separating said sour water in a purified water stream and sour stream, directing said sour stream as a liquid sour recycle stream either to contact said material catalytically active in hydroprocessing or to be combined with said hydroprocessed stream prior to step b,
said material catalytically active in hydroprocessing comprising at least one base metal from Group 5, 8, 9 or 10 of the periodic table in sulfided state.




This has the benefit of minimizing or even avoiding the need for addition of sulfur to keep the catalytically active material in the active sulfided state.

Abstract: A process and a process plant for conversion of a reactive liquid feedstock stream containing at least 40 wt % carbon, including the steps of directing a diluent stream, having a first combined hydrogen consumption potential and the reactive liquid feedstock stream as a combined stream having a first hydrogen consumption potential, to contact a material catalytically active in hydrotreatment which during operation has a lowest temperature of at least 80° C. and a highest temperature of less than 250° C. in the presence of dihydrogen, withdrawing a stabilized composition stream having a second combined hydrogen consumption potential which is less than 80% and more than 10% of the first hydrogen consumption potential, and providing an amount of the liquid phase of said stabilized composition stream as said diluent stream wherein the hydrogen consumption potential for a composition is the amount of hydrogen required for conversion of the composition into a saturated hydrocarbon.

Abstract: The present invention relates to a composition comprising, on water free basis, at least 80 wt % molecules comprising from 8 to 35 C-atoms, said composition having a flash point above 60° C. and comprising, on water free basis, 9.5-12 wt % H, 3-45 wt % O and less than 5 wt ppm halogens, the use of such a composition as a marine fuel and a process for producing such a composition by partial hydrodeoxygenation.

Abstract: Process and plant for hydrotreating a liquid oil feedstock stream comprising the steps of i) conducting the liquid oil feedstock stream to a stabilization step by reacting the liquid oil stream with hydrogen in the presence of a catalyst for producing a stabilized composition, and separating therefrom: a stabilized stream comprising a gas phase, and a stabilized liquid oil stream; ii) providing a main hydrodeoxygenation (HDO) step, comprising: ii)-1 conducting at least a portion of said stabilized stream comprising a gas phase, or a stabilized feed stream combining at least a portion of said stabilized stream comprising a gas phase and a portion of said stabilized liquid oil stream, to a main hydrodeoxygenation (HDO) step in a first bed active in hydrodeoxygenation (HDO), thereby producing a first main hydrotreated effluent stream; ii-2) combining at least a portion of said stabilized liquid oil stream with said first main hydrotreated effl-uent stream, thereby producing a first mixed stabilized gas-liquid oil stream; ii-3) con-ducting said first mixed stabilized gas-liquid oil stream to a subsequent bed active in HDO, thereby producing a main hydrotreated effluent stream.
