| titleOfInvention | Pretreatment process of a zeolite-EUO based catalyst under drastic conditions |
| abstract | A process for pretreating a catalyst used in a process for isomerizing a hydrocarbon charge containing at least one eight carbon aromatic compound selected from para-xylene, ortho-xylene, meta-xylene and ethylbenzene, the catalyst having at least one Zeolite of the structural type EUO, which has a crystal size below 0.2 microns, and at least one hydrogenation / dehydrogenating metal, the method comprising the following steps: a) sulfurization of the catalyst under a neutral or reducing atmosphere in the presence of at least one sulfur compound selected from the alkyl sulfur compounds, aryl sulfur compounds and alkylaryl sulfur compounds, wherein the sulfurization step at a temperature between 20 ° C and 500 ° C, at an absolute pressure between 0.1 and 5 MPa and with a gas volume per catalyst volume and hour between 50 and 600 h -1 is carried out; b) Treatment of the catalyst in the presence of the hydrocarbon charge, at a temperature between 400 ° C and 500 ° C, for a period of 72 to 120 hours and c) treating the hydrocarbon charge and the catalyst by applying a temperature lower than the value used in step b), wherein the temperature used in step b) is at least 20 ° C higher than the temperature used in step c) and the pressure used in step b) is at least 0.3 MPa higher than the pressure used in step c). |
