EU- 1 ZEOLITE CATALYST AND A PROCESS FOR THE REDUCTION OF THE POUR POINT OF FEEDS CONTAINING PARAFFINS

摘要

THE INVENTION CONCERNS A PROCESS FOR IMPROVING THE POUR POINT OF A FEED COMPRISING PARAFFINS CONTAINING MORE THAN 10 CARBON ATOMS, IN WHICH PROCESS THE FEED TO BE TREATED IS BROUGHT INTO CONTACT WITH A CATALYST COMPRISING AN EU-1 ZEOLITE AND AT LEAST ONE HYDRO-DEHYDROGENATING ELEMENT, AT A TEMPERATURE WHICH IS IN THE RANGE 170°C TO 500°C, A PRESSURE IN THE RANGE 1 TO 250 BAR AND AN HOURLY SPACE VELOCITY IN THE RANGE 0.05 TO 100 H-L, IN THE PRESENCE OF HYDROGEN IN A PROPORTION OF 50 TO 2000 1/1 OF FEED. THE OILS OBTAINED HAVE GOOD POUR POINTS AND HIGH VISCOSITY INDICES (VI). THE PROCESS IS ALSO APPLICABLE TO GAS OILS AND OTHER FEEDS REQUIRING A REDUCTION OF POUR POINT. THE INVENTION ALSO CONCERNS AN EU-1 ZEOLITE FROM WHICH A PORTION OF ELEMENTS T (AL, GA, FE OR B) HAVE BEEN REMOVED AND WHICH HAS AN SI/T ATOMIC RATIO OF AT LEAST 10.
