Two-bed catalyst arrangement for hydrodesulrurization of crude oil
Abstract
Abstract A TWO-BED HYDRODESULFURIZATION OF CRUDE OIL OR REDUCED CRUDE OIL CONTAINING THE ALIPHALTENE FRACTION OF THE CRUDE IS CARRIED OUT WITH CATALYTIC PARTICLES OF A GROUP VI AND GROUP VIII METAL SUPPORTED ON A NON-CRACKING ALUMINA. IN THE FIRST BED AT LEAST 50% OF THE TOTAL PORE VOLUME OF SAID CATALYST HAS PORES WITH RADII IN THE 50-100 ANGSTROM RANGE, IN TE SECOND BED LESS THAN 45% OF THE TOTAL PORE VOLUME OF SAID CATALYST HAS PORES WITH RADII IN THE 50-100 ANGSTROM RANGE. THE HIGHER PERCENTAGE OF PORES IN THE FIRST BED PROVIDES INCREASED SULFUR SELECTIVITY WHILE THE LESSER PERCENTAGE OF PORES IN THE SECOND BED PROVIDES ENHANCED AGING CHARACTERISTIC FOR THE COMBINED CATALYST BEDS.
