Abstract: A process to treat a heavy hydrocarbon feed in a liquid-full hydroprocessing reactor is disclosed. The heavy feed has a high asphaltenes content, high viscosity, high density and high end boiling point. Hydrogen is fed in an equivalent amount of at least 160 liters of hydrogen, per liter of feed, l/l (900 scf/bbl). The feed is contacted with hydrogen and a diluent, which comprises, consists essentially of, or consists of recycle product stream. The hydroprocessed product has increased value for refineries, such as a feed for an fluid catalytic cracking (FCC) unit.

Abstract: A process for hydroprocessing hydrocarbons in a combined targeted pretreatment and selective ring-opening unit wherein the targeted pretreatment comprises at least two stages in a single liquid recycle loop. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase. Heavy hydrocarbons and light cycle oils can be converted in the process to provide a liquid product having over 50% in the diesel boiling range, with properties to meet use in low sulfur diesel.

Abstract: The present invention provides a process for hydroprocessing comprising treating a hydrocarbon feed in a first two-phase hydroprocessing zone having a liquid recycle, producing product effluent, which is contacted with a catalyst and hydrogen in a downstream three-phase hydroprocessing zone, wherein at least a portion of the hydrogen supplied to the three-phase zone is a hydrogen-rich recycle gas stream. Optionally, the product effluent from the first two-phase hydroprocessing zone is fed to a second two-phase hydroprocessing zone containing a single-liquid-pass reactor. The two-phase hydroprocessing zones comprise two or more catalyst beds disposed in liquid-full reactors. The three-phase hydroprocessing zone comprises one or more single-liquid-pass catalyst beds disposed in a trickle bed reactor.

Abstract: The present invention provides a process for hydroprocessing hydrocarbons in liquid full reactors with one or more independent liquid recycle streams. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase and one or more of the recycle streams may actually be zero. Hydrocarbons can be converted in the process to provide liquid products such as clean fuels with multiple desired properties.

Abstract: The present invention provides a process for hydroprocessing hydrocarbons with uneven catalyst volume distribution among two or more catalyst beds. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase. Hydrocarbons can be converted in the process to provide a liquid product including clean fuels with multiple desired properties such as low density and high cetane number.
