摘要: Methods for synthesizing a mesoporous nano-sized zeolite beta are described. The method may include mixing an aqueous base solution with hexadecyltrimethylammonium bromide (CTAB) to form a first solution; adding nano-sized zeolite particles having a particle size of less than or equal to 100 nm to the first solution to form a second solution. The nano-sized zeolite particles include a microporous framework with a plurality of micropores having diameters of less than or equal to 2 nm and a BEA framework type. The method may further include transferring the second solution to an autoclave operated at 25° C. to 200° C. for 3 to 24 hours to form a colloid; drying the colloid at 100° C. to 200° C. for 8 to 36 hours without washing the colloid to form a zeolite precursor; and calcining the zeolite precursor at 250° C. to 600° C. for 1 to 8 hours to form the mesoporous nano-sized zeolite beta.

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.

摘要: Methods for synthesizing a mesoporous nano-sized ultra-stable Y zeolite include combining a microporous Y zeolite having a SiO2/Al2O3 molar ratio of less than 5.2 with water to form a microporous Y zeolite slurry and heating the microporous Y zeolite slurry to 30° C. to 100° C. to form a heated microporous Y zeolite slurry. Further the method includes adding a 0.1M to 2.0M ammonium hexafluorosilicate solution and a 0.1M to 2.0M ammonium hydroxide solution in a drop-wise manner, either sequentially or simultaneously, to the heated microporous Y zeolite slurry to form a treated zeolite solution and holding the treated zeolite solution at 50° C. to 100° C. 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: A process for converting crude oil may comprise contacting a crude oil with one or more hydroprocessing catalysts to produce a hydroprocessed effluent and contacting the hydroprocessed effluent with a fluidized catalytic cracking (FCC) catalyst composition in an FCC system to produce cracked effluent comprising at least olefins. The crude oil may have an API gravity from 30 to 35. The FCC system may operate at a temperature of greater than or equal to 580° C., a weight ratio of the FCC catalyst composition to the crude oil of from 2:1 to 10:1, and a residence time of from 0.1 seconds to 60 seconds. The FCC catalyst composition may comprise ultrastable Y-type zeolite (USY zeolite) impregnated with lanthanum; ZSM-5 zeolite impregnated with phosphorous; an alumina binder; colloidal silica; and a matrix material comprising Kaolin clay.

摘要: An integrated process for conversion of a hydrocarbon stream comprising light naphtha to enhanced value products. The process includes passing the hydrocarbon stream through a first reactor, the first reactor being a catalytic bed reactor with a dual-function catalyst to simultaneously reform light naphtha to BTEX and crack light naphtha to ethane, propane, and butanes. Further, the process includes passing an effluent of the first reactor to a gas-liquid separating unit to generate a liquid stream and a gas stream, and passing the gas stream to a gas separator unit to remove hydrogen gas and methane and generate an enhanced gas stream. The process further includes passing the enhanced gas stream through a second reactor, the second reactor being a pyrolysis unit operated at steam cracking conditions to convert ethane, propane, and butanes in the enhanced gas stream to light. An associated system for performing the process is also provided wherein the integrated process does not include passage of a process stream to a separate and independent hydrocracking unit to crack light alkanes in the hydrocarbon stream to smaller alkanes.

摘要: Examples described herein provide a method for characterizing a catalyst in a chemisorption unit. The method includes treating a catalyst sample with gas blend comprising ammonia in an inert gas and performing a first temperature programmed desorption (TPD) to desorb the ammonia from the catalyst sample. A temperature programmed reduction (TPR) of the catalyst sample is performed with hydrogen. The catalyst sample is treated after the TPR with a gas blend comprising ammonia in an inert gas. A second temperature programmed desorption is performed to desorb the ammonia from the catalyst sample.
