  • Publication number: 20060127305
    Abstract: The invention concerns a process for treating a hydrocarbon feed comprising a series of a first upstream process for hydrocarbon hydroconversion comprising at least one reaction chamber, the reaction or reactions occurring inside said chambers and employing at least one solid phase, at least one liquid phase and at least one gas phase, and a second downstream steam reforming process comprising at least one reaction chamber, characterized in that the said upstream process is carried out in a “slurry” and/or an ebullated bed mode and in that the downstream process comprises a first step for at least partial conversion of hydrocarbons heavier than methane into methane, termed the pre-reforming step, and in that the reaction or reactions occurring inside the chambers of the downstream stream reforming process enables the production of a reagent, namely hydrogen, which is necessary for the reactions in the first upstream process.

  • Publication number: 20060118463
    Abstract: This invention relates to a novel integrated method for economically processing vacuum residue from heavy crude oils. This is accomplished by utilizing a solvent deasphalter (SDA) in the first step of the process with a C3/C4/C5 solvent such that the DAO product can thereafter be processed in a classic fixed-bed hydrotreater or hydrocracker. The SDA feed also includes recycled stripper bottoms containing unconverted residue/asphaltenes from a downstream steam stripper unit. The asphaltenes from the SDA are sent to an ebullated-bed reactor for conversion of the residue and asphaltenes. Residue conversion in the range of 60-80% is achieved and asphaltene conversion is in the range of 50-70%. The overall residue conversion, with the DAO product considered non-residue, is in the range of 80 W %-90 W % and significantly higher than could be achieved without utilizing the present invention.

  • Publication number: 20060060501
    Abstract: The invention relates to a process for hydroconversion in a reaction zone (preferably in a bubbling bed and/or in slurry) of liquid heavy hydrocarbon feedstocks containing sulphur, in the presence of hydrogen and a catalytic solid phase, said solid phase being obtained from a catalytic precursor, a process in which the catalytic precursor is injected into a part of the liquid conversion products which contain dissolved hydrogen sulphide, asphaltenes and/or resins, under temperature and pressure conditions close to those at which they leave the reaction zone, and the obtained mixture is injected into the reaction zone. Preferably, the catalytic precursor is injected into the part of the conversion effluents that is recycled to the reactor inlet. The invention also relates to a device that can be used for implementing this process.
