A process for upgrading a hydrocarbonaceous feedstock which process included separating the feedstock in the presence of hydrogen at elevated temperature and a partial hydrogen pressure greater than 50 bar into a high boiling fraction and a low boiling fraction and subjecting at least part of the low boiling fraction substantially boiling in the gasoline range to a hydrotreating step under substantially the same conditions as prevailing in the separation step, and recovering from the hydrotreating step a product substantially boiling in the gasoline range and being of improved quality.
