Patent-family-84569583

The present disclosure relates to a process for hydroprocessing a feedstock comprising oxygenates, comprising the steps of a. directing said feedstock, an amount of make-up hydrogen and a recycle gas to contact a catalyst active in hydroprocessing under active hydroprocessing conditions, to provide a hydroprocessed product stream, b. separating from the hydroprocessed product stream a vapor product fraction and a liquid product fraction by gas liquid separation at a pressure above 80% of said active hydroprocessing conditions and a temperature above 200°C, c. separating from the vapor product fraction a gaseous product fraction and a light liquid product fraction by gas/liquid separation at a pressure above 80% of said active hydroprocessing conditions and a temperature below 100°C, d. directing at least an amount of said gaseous product fraction to a means of gas purification to provide a hydrogen rich gas fraction depleted in molecules with a molecular weight above 12 g/mole and a hydrogen depleted gaseous fraction enriched in molecules with a molecular weight above 12 g/mole, e. providing at least an amount of said hydrogen rich gas fraction as a portion of said recycle gas or make-up hydrogen. This has the associated benefit of providing a pure recycle gas also for partially hydroprocessed product streams, which have a low capacity for capturing CO₂, CO and CH₄.
