Objective
The work performed on offerite and omega included preparation, characterization and catalytic testing, and gave interesting results which could lead to improvements in existing industrial catalysts, especially for isomerization.
The objectives were to improve the resistance of gasoils against cold by dewaxing and to increase the octane numbers of C5-C6 straight run light petrol by isomerization.
About 20 samples were prepared with different silicon to aluminium ratios by various dealumination treatments like self-steaming and/or acid leaching in different conditions. Several techniques like electronic microscopy, X-ray photoelectron spectroscopy, infra-red, and thermal programmed desorption were used to characterize them.
Samples were prepared with different silicon to aluminium ratios. To select the best samples, they were subjected to test reactions like ethylbenzene disproportionation, n-dodicane hydrocracking and C5/C7 paraffins hydroisomerization.
2 catalysts were outstanding enough to be evaluated on an industrial scale - dealuminated offretite and dealuminated omega.
Promising catalytic results were obtained with dealuminated offretite associated to an hydrogenating function like nickel-molybdenum dewaxing, particularly in terms of stability and with dealuminated omega associated to platinum for isomerisation. This last catalyst leads to more active, selective and stable catalysts, and it seems that the increase of octane number obtained can economically compensate the higher price of omega zeolite.
THE PURPOSE OF THE PROJECT IS TO DEVELOP DEWAXING CATALYSTS FOR GASOILS AND WAX ISOMERISATION CATALYSTS WITH 5 TO 6 ATOMS OF CARBON FROM RESPECTIVELY TWO ZEOLITES, OFFRETITE AND OMEGA.
ACHIEVEMENT OF THIS TARGET REQUIRES OPTIMIZATION OF THE SYNTHESIS OF THESE TWO ZEOLITES AND ADJUSTMENT BY MODIFICATION (ELIMINATION OF ALKALINE IONS AND OF ALUMINIUM) OF THEIR ACIDITY WHICH IS THE ORIGIN OF CRACKING AND-OR ISOMERISATION REACTIONS THAT NEED TO BE ENHANCED IN THE TWO CATALYTIC OPERATIONS.
