    摘要： The present invention relates to a process for the hydroconversion of mixtures of polymers or plastics which comprises the pre-treatment of the mixtures through methods selected from mechanical methods, chemical methods, thermal methods, or combinations thereof forming a pre-treated charge. The pre-treated charge is mixed with a hydrocarbon vacuum residue, optionally pre-heated, to form a reactant mixture. The reactant mixture is fed to a hydroconversion section in slurry phase, together with a catalyst precursor containing Molybdenum, and a stream containing hydrogen, forming a reaction effluent. The effluent is separated into at least one high-pressure and high-temperature separator in a vapour phase and a slurry phase. The separate vapour phase is sent to a gas treatment section with the function of separating a liquid fraction from the gas containing hydrogen and hydrocarbon gases having from 1 to 4 carbon atoms; said liquid fraction comprising naphtha, atmospheric gas oil (AGO), vacuum gas oil (VGO). The slurry phase is then sent to a separation section that has the function of separating the fractions of the Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO), from a stream of heavy organic products which contains asphaltenes, unconverted charge, catalyst and solid formed during the hydroconversion reaction. This stream of heavy organic products is partly recirculated to the hydroconversion section and partly forms a purge stream.

    摘要： An ebullated bed process for the hydroconversion of heavy hydrocarbon feedstocks that provides for high conversion of the heavy hydrocarbon with a low sediment yield. The process uses for its catalyst bed small particles of a specifically defined shaped hydroprocessing catalyst which is contacted with the heavy hydrocarbon feedstock under hydroconversion conditions and yields a hydrocarbon conversion having a relatively low sediment content.

    摘要： Methods and systems for slurry hydrocracking with reduced feed bypass and methods for modulating an amount of toluene insoluble material present in a slurry hydrocracking reactor are provided. An exemplary slimy hydrocracking method comprises the steps of: combining a hydrocarbon feed and a slurry hydrocracking catalyst or catalyst precursor to generate a slurry hydrocracking feed; introducing the slurry hydrocracking feed to a slurry hydrocracking reactor under hydrocracking conditions suitable to generate a first product stream; drawing a drag stream from the slurry hydrocracking reactor, the drag stream comprising a hydrocarbon, mesophase material, and solid catalyst particles; separating the drag stream into a first separated stream and a recycle stream, with the first separated stream comprising mesophase material and solid catalyst particles, and the recycle stream comprising the hydrocarbon; and directing the recycle stream into the slurry hydrocracking reactor.
