摘要： Methods for synthesizing a mesoporous nano-sized ultra-stable Y zeolite include adding sodium aluminate and colloidal silica to an aqueous NaOH solution and mixing to form a hydrogel having a molar ratio composition of 8 to 12 Na2O:Al2O3:14 SiO2:200 to 400 H2O. The method further includes heating the hydrogel to an autoclave to form a zeolite precursor which is filtered and washed to form a nano-sized Y zeolite. Further the method includes combining the nano-sized Y zeolite with water to form a nano-sized Y zeolite slurry mixture and then adding a 0.1 to 2.0 M aqueous solution of ammonium hexafluorosilicate to form a dealuminated solution. Finally the method includes filtering and washing the dealuminated solution with water to form an ultra-stable Y zeolite precursor, drying the ultra-stable Y zeolite precursor, and calcining the dried zeolite precursor to form the nano-sized ultra-stable Y zeolite.

摘要： Methods for synthesizing a nano-sized zeolite beta are described. The method may include mixing alumina and tetraethylammonium hydroxide to form an aluminum solution; mixing silica, additional TEAOH, and water to form a silica slurry; and adding the aluminum solution into the silica slurry and mixing to form an aluminosilicate gel. The method may further include transferring the aluminosilicate gel to an autoclave operated at 120° C. to 160° C. for 2 to 4 days at a rotational speed of 60 to 100 rotations per minute to form a zeolite precursor colloid; washing the zeolite precursor colloid with water to form a washed colloid; drying the washed colloid at 80° C. to 150° C. for 6 to 24 hours to form a zeolite precursor; and calcining the zeolite precursor at 400° C. to 650° C. for 2 to 8 hours to form the nano-sized zeolite beta.

摘要： An integrated hydrotreating and hydrocracking process includes contacting a hydrocarbon oil stream with a hydrogen stream and a hydrotreating catalyst in a moving-bed hydrotreating reactor, thereby producing a hydrocarbon product stream and a spent hydrotreating catalyst; contacting the hydrocarbon product stream with a second hydrogen stream and a hydrocracking catalyst in a hydrocracking reactor, thereby producing a hydrocracked hydrocarbon product stream; processing the spent hydrotreating catalyst to produce regenerated hydrotreating catalyst; and recycling the regenerated hydrotreating catalyst to the moving-bed hydrotreating reactor.

摘要： A system for upgrading heavy hydrocarbon feeds, such as crude oil, include a hydrotreating unit, a hydrotreated effluent separation system, a solvent-assisted adsorption system, and a hydrocracking unit. Processes for upgrading heavy hydrocarbon feeds include hydrotreating the hydrocarbon feed to produce a hydrotreated effluent that includes asphaltenes, separating the hydrotreated effluent into a lesser boiling hydrotreated effluent and a greater boiling hydrotreated effluent comprising the asphaltenes, combining the greater boiling hydrotreated effluent with a light paraffin solvent to produce a combined stream, adsorbing the asphaltenes from the combined stream to produce an adsorption effluent, and hydrocracking the lesser boiling hydrotreated effluent and at least a portion of the adsorption effluent to produce a hydrocracked effluent with hydrocarbons boiling less than 180° C. The systems and processes increase the hydrocarbon conversion and yield of hydrocarbons boiling less than 180° C.
