    摘要： The invention relates to a process for producing LPG and BTX, comprising a) subjecting a mixed hydrocarbon feedstream to first hydrocracking in the presence of a first hydrocracking catalyst to produce a first hydrocracking product stream; b) separating the first hydrocracking product stream to provide at least a light hydrocarbon stream comprising at least C2 and C3 hydrocarbons, a middle hydrocarbon stream comprising C4 and/or C5 hydrocarbons and a heavy hydrocarbon stream comprising at least C6+ hydrocarbons and c) subjecting the heavy hydrocarbon stream to second hydrocracking to produce a second hydrocracking product stream comprising BTX, wherein the second hydrocracking is more severe than the first hydrocracking, wherein at least part of the middle hydrocarbon stream is recycled back to the first hydrocracking in step a).

    摘要： A method to prepare an improved catalyst feed to a system to upgrade heavy oil. The method comprises: providing a spent catalyst that has been used in a hydroprocessing operation has with a solid content ranging from 5 to 50 wt. % in soluble hydrocarbons and having less than 80% but more than 10% of original catalytic activity; removing at least 50% of the soluble hydrocarbons removed in a deoiling step; treating the deoiled spent catalyst with a treating solution containing at least one of plain water, a mineral acid, an oxidizing agent, and combinations thereof to reduce the concentration of at least one metal contaminant in the deoiled spent catalyst by at least 40%. After treatment, the treated deoiled spent catalyst is slurried in a hydrocarbon medium, and fed to the heavy oil upgrade system as part of the catalyst feed system with a fresh slurry catalyst.

    摘要： A process for hydrocracking a hydrocarbon feedstock having a propensity to form polynuclear aromatic hydrocarbon compounds to suppress fouling the processing unit. The hydrocracking method includes contacting the hydrocarbon feedstock with a crystalline zeolite hydrocracking catalyst, contacting at least a portion of the resulting unconverted hydrocarbon oil containing polynuclear aromatic compounds with an iron catalyst in the presence of hydrogen to hydrogenate and hydrocrack the polynuclear aromatic hydrocarbon compounds, and recycling unconverted hydrocarbon oil having a reduced concentration of polynuclear aromatic compounds to the hydrocracking zone.
