摘要： The present disclosure relates to a process and a process plant for conversion of a reactive liquid feedstock stream containing at least 40 wt% carbon, comprising the steps of a. 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, b. 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, c. providing an amount of the liquid phase of said stabilized composition stream as said diluent stream wherein the hydrogen consumption potential for a composition shall be understood as the amount of hydrogen required for conversion of the composition into a saturated hydrocarbon. This has the associated benefit of the diluent being only partly converted and thus having a chemical nature favoring miscibility with the reactive feedstock, such that material catalytically active in hydrotreatment is contacted with a mixed liquid which is uniform, and which due to the dilution is less prone to polymerization and has a higher heat capacity, relative to the reactivity.

摘要： The present disclosure relates to a process, a process plant and equipment for conversion of a feedstock rich in oxygenates to a hydrocarbon comprising the steps of directing said feedstock in combination with a recycle gas stream to a hydroprocessing step, to provide a two-phase hydroprocessed process stream comprising at least hydrogen, methane andhydrocarbons, combining a methane lean stream of hydrocarbons being liquid at ambient temperature, with a methane donor stream being either (i) said two-phase hydroprocessed process stream comprising methane or (ii) a gaseous stream derived from the two-phasehydroprocessed process stream by phase separation, to provide a multiple-phase combined stream, separating said multiple-phase combined stream in at least a hydrogenrich gas stream comprising a majority of the hydrogen comprised in said a hydroprocessed process stream and a rich liquid hydrocarbon stream comprising absorbed methane, in a desorption step desorbing an amount of methane from said rich liquid hydrocarbon stream by a flashing process or by a stripping process, to provide a methane rich gas phase and a liquid product stream of hydrocarbons, wherein the methane rich gas phase has a higher concentration of methane than the gas phase of the methane donor stream. This has the associated benefit of such a process being efficient in reducing the amount of methane in the recycle gas stream, which enables an increased partial pressure of hydrogen by facilitating release of methane in a separate stream.

摘要： A broad aspect of the present disclosure relates to a process for hydroprocessing of a hydrocarbonaceous feedstock stream comprising the steps ofdirecting said hydrocarbonaceous feedstock stream to contact a material catalytically 5active in hydroprocessing thus providing a hydroprocessed streamseparating 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 10catalytically active in hydroprocessing or to be combined with said hydroprocessed stream prior to step b characterized in 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 15keep the catalytically active material in the active sulfided state.

摘要： A broad aspect of the present disclosure relates to a process for conversion of a feed-stock containing at least 5 wt% aromatics, originating from thermal decomposition of solids, comprising the steps of directing the feedstock to contact a material catalytically active in hydrodeoxygenation under hydrodeoxygenation conditions in the presence of dihydrogen, to provide a deoxygenated intermediate, directing at least an amount of the deoxygenated intermediate to contact a material catalytically active in hydrodearomatization under hydrodearomatization conditions in the presence of dihydrogen, to provide an dearomatized intermediate.This has the associated benefit of converting a feedstock such as pyrolysis oil to a product or an intermediate compatible with diesel fuel requirements with a minimal yield loss.
