Abstract: IMPROVED HYDROCARBON CATALYSTS ARE PREPARED BY TREATING CERTAIN ZEOLITES WITH HYDROGEN FLUORIDE. IT IS PREFERRED THAT THE HYDROGEN FLUORIDE TREATMENT BE ACCOMPLISHED AFTER THOSE PREPARATION STEPS REQUIRING CONTACT OF THE ZEOLITE WITH WATER AT HIGH TEMPERATURES. IT IS ALSO PREFERRED THAT THE ZEOLITE WHICH IS SUBJECTED TO THE HF TREATMENT HAVE A SUBSTANTIAL PORTION OF IS ALKALI METAL CONTENT REPLACED BY THE HYDROGEN ION.

Abstract: IMPROVED HYDROCARBON CONVERSION CATALYST COMPRISES AT LEAST TWO CRYSTALLINE ALUMINOSILICATE ZEOLITES HAVING ESSENTIALLY THE SAME CRYSTAL STRUCTURES, BUT HAVING SUBSTANTIALLY DIFFERENT SIO2/AL2O3 MOLAR RATIOS. MIXTURES OF ZEOLITES X AND Y ARE PREFERRED, PARTICULARLY WHEN EMBEDDED IN A MATRIX INCLUDING CLAYS AND/OR SILICA-ALUMINA.

Abstract: PETROLEUM FRACTIONS BOILING ABOVE 200*F. ARE DESULFURIZED IN TWO STAGES IN THE PRESENCE OF A SULFUR-RESISTANT CATALYST, THE FIRST STAGE BEING CARRIED OUT IN THE ABSENCE OF HYDROGEN AND THE SECOND IN THE PRESENCE OF HYDROGEN. THE CATALYST DEACTIVATES RAPIDLY IN THE FIRST STAGE AND IS REGENERATED BY STRIPPING WITH HYDROGEN OR MIXTURES OF HYDROGEN AND HYDROGEN SULFIDE.
