摘要:
This invention relates to a new and useful improvement in a process for upgrading petroleum residua. The process comprises contacting a vacuum or atmospheric resid feed with a metal-containing lanthana-alumina-aluminum phosphate catalyst whereby the resid feedstock is simultaneously demetallized and desulfurized.

This invention relates to a new catalyst composition. The catalyst composition comprises a catalytic component and a support comprising an amorphous combination of lanthana, alumina and aluminum phosphate, and may be characterized after calcination by a pore size distribution including about 5 to 20 vol. % within the pore size diameter range of 50 to 100 Angstroms, about 10 to 35 vol. % within the pore size diameter range of 100 to 150 Angstroms, about 15 to 50 vol. % within the pore size diameter range of 150 to 200 Angstroms and about 10 to 50 vol. % within the pore size diameter range of 200 to 400 Angstroms.

摘要:
The catalyst composition comprises a layered metal oxide and/or sulfide of a metal selected from the group consisting of Group VB and VIB metals and containing inserted atomic hydrogen therein, with no chemical bond between said atomic hydrogen and anionic oxygen or anionic sulfur of the oxide or sulfide. It is useful for demetallizing resids.

The catalytic cracking of a hydrocarbon oil to provide a product of increased octane number and increased C.sub.5 + gasoline content is carried out employing a cracking catalyst composition containing both a large pore crystalline zeolite component and an MCM-22 zeolite component.
摘要:
This invention relates to a method of preparing a metal-containing amorphous magnesia-alumina-aluminum phosphate catalyst support involving the admixture of an organic cation having a size equal to or greater than 2 Angstroms, the organic cation preferably being a tertiary or a tetraalkylammonium or phosphonium cation. The method permits recovery of a catalyst support having a controlled pore size distribution. The invention also relates to an improved catalytic support as well as an improved petroleum residua upgrading process comprising hydrotreating residua in the presence of the improved catalyst support.
摘要:
Low acidity refractory oxide-bound zeolite catalysts, for example, silica-bound ultrastable Y zeolite, possessing physical properties, e.g., crush strength, similar to those of their alumina-bound counterparts are described. Since low acidity refractory oxide-bound catalysts are inherently less active than alumina-bound zeolite catalysts, the former are particularly useful in hydrocarbon conversion processes in which reduced coke make increases catalyst cycle length. Due to their stability in acid environments, the low acidity refractory oxide-bound zeolite extrudate herein can be acid treated without unduly compromising its structural integrity.
