摘要
PROBLEM TO BE SOLVED: To provide a method for removing polynuclear aromatic compounds (PNA) in a hydrocracking process.;SOLUTION: The raw material oil is hydrocracked in a hydrocarbon reactor 4 and an unconverted fraction 11 separated from the liquid products in a fractionation zone 9 is recycled to the hydrocarbon reactor after the polynuclear aromatic compounds (PNA) contained therein are removed by adsorption by an adsorbent based on alumina-silica having a controlled macropore content as a pore volume measured by the mercury porosimetry in adsorption zones 17 and 18.;COPYRIGHT: (C)2007,JPO&INPIT
