摘要： Process for hydrogenating aromatic compounds containing sulfur impurities by contacting the same, at a temperature in the range of from 200* to 450*C and under a pressure of from 10 to 200 Kg/cm2, in a first step, with a catalyst containing a desulfurizing element selected from the oxides and/or sulfides of molybdenum, tungsten, nickel and cobalt, and an iron oxide, deposited on an alumina carrier used in an amount of 0.25 to 4 times the iron oxide amount, and in a second step, with a metal hydrogenation catalyst.

摘要： IN THE HYDROGENATION OF AROMATIC AND OLEFIN HYDROCARBONS CONTAINING ABOUT 1-200 PARTS PER MILLON BY WEIGHT OF SULFUR, NICKEL AND COBALT CATALYSTS ARE DEACTIVATED AND ARE DIFFICULATE TO REGENERATED. IF HOWEVER, A SILICA CARRIER IS EMPLOYED, THE REGENERATION OF THE CATALYSTS CAN BE ACCOMPLISHED BY THE SUCCESSIVE STEPS OF HEATING THE DEACTIVATED CATALYSTS WITH A GAS CONTAINING MOLECULAR OXYGEN AT 300-600*C., CONTACTING RESULTANT COOLED CATALYST WITH LIQUID WATER AT ABOUT 0-250*C. AND THE WITH HYDROGEN AT 200-500*C. THIS REGENERATION PROCESS DOES NOT WORK SATISFACTORY WITH ALUMINA AS A CARRIER.
