Abstract: A process plant and a method for producing a hydrocarbon mixture suitable for use as an aviation fuel having an end-boiling point according to ASTM D86 below 300° C. from a decarboxylation feedstock being a feedstock including fatty acid esters and/or triglycerides and including C18 side-chains, to a deoxygenated hydrocarbon mixture by directing the decarboxylation feedstock to contact a material catalytically active in decarboxylation under decarboxylation conditions where the ratio between deoxygenation by formation of carbon oxides and deoxygenation by formation of water is at least 1.5:1, 2:1 or 3:1, as measured by the ratio of C17 paraffins to C18 paraffins in the deoxygenated hydrocarbon mixture, with the associated benefit of such a decarboxylation based method selectively reducing the product carbon length by a single carbon atom, compared to a hydrodeoxygenation based method, which is beneficial for processes requiring a moderate reduction of end boiling point.

Abstract: Process for producing methane or methanol, said process comprising the steps of: i) conducting a solid renewable feedstock to a thermal decomposition step, this being a pyrolysis step or a hydrothermal liquefaction step, for producing: a first off-gas stream comprising hydrocarbons, a solid carbon stream, and optionally a first liquid oil stream; upgrading the first off-gas stream by conducting it to a hydro/deoxygenation (HDO/DO) step i.e. hydrodeoxygenation or deoxygenation step in which said HDO/DO step is conducted in the absence of steam, and a subsequent separation step, for generating water, a second liquid oil stream and an upgraded first off-gas stream; ii) conducting the first off-gas stream or the upgraded first off-gas stream to an olefin removal step, for generating a further upgraded first off-gas stream which is free of olefins; iii-1) conducting the first off-gas stream, or the upgraded first off-gas stream, or the further upgraded first off-gas stream, to a methanation step under the generation of steam for producing said methane; or iii-2) conducting the first off-gas stream, or the upgraded first off-gas stream, or the further upgraded first off-gas stream, to a steam reforming step for producing a methanol synthesis gas and subsequently conducting the methanol synthesis gas to a methanol synthesis step under the generation of steam for producing said methanol; iv) conducting steam, such as at least a portion of the steam generated in step iii-1) or iii-2), to an electrolysis step for producing an oxygen stream and a hydrogen stream; v) conducting at least a portion of the hydrogen stream from the electrolysis step to any of the: thermal decomposition step including HDO-step, olefin hydrogenation step, methanation step, methanol synthesis step, or combinations thereof.

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: A process for conversion of a feedstock originating from thermal decomposition of solids, containing from at least 0.5 wt % nitrogen and less than 15 wt % nitrogen, including the steps of directing the feedstock to contact a material catalytically active in hydrotreatment under active hydrotreatment conditions in the presence of dihydrogen, to provide a hydrotreated intermediate, adjusting one or more conditions of the hydrotreated intermediate stream to active hydrodearomatization conditions where the equilibrium between aromatic nitrogen compounds and non-aromatic nitrogen-free compounds is shifted towards non-aromatic nitrogen-free compounds, directing at least an amount of the hydrotreated intermediate to contact a material catalytically active in hydrodearomatization under the active hydrodearomatization conditions, in the presence of dihydrogen, to provide a further converted intermediate. This has the associated benefit of providing a pyrolysis plant with the ability to remove aromatic nitrogen efficiently from the pyrolysis oil.

Abstract: The invention relates to a process for hydrotreating a liquid oil stream such as pyrolysis oil stream by, in continuous operation, reacting the liquid oil stream with hydrogen in the presence of a nickel-molybdenum (Ni—Mo) based catalyst at a temperature of 20-240° C., a pressure of 100-200 barg and a liquid hourly space velocity (LHSV) of 0.1-1.1 h−1, and a hydrogen to liquid oil ratio, defined as the volume ratio of hydrogen to the flow of the liquid oil stream, of 1000-6000 NL/L thereby forming a stabilized liquid oil stream.
