Technical equilibrium can be used to measure a single gas isotherm in a relatively fast and continuous manner rather than, for example, in a batch manner. Further, an expansion vessel can be used for successive desorption a multicomponent gas in combination with determining the composition of the multicomponent gas in combination with a calculation that provides both qualitative and quantitative information about the multicomponent gas. Moreover, a multicomponent gas can be flowed through an adsorbent bed and the and the flow of the multicomponent gas flow is shut off and isolated when equilibrium is reached.

Multifunctional volumetric adsorption test units and methods of using same

Processes for producing products from crude oil include separating the crude oil into at least a lesser boiling point fraction and a greater boiling point fraction and passing the fractions to a reactor system that includes a riser section and a downer section. An outer boundary of the downer section is defined by a first wall in a plane perpendicular to a central axis, and outer boundaries of the riser section are defined by the first wall and a second wall in the plane perpendicular to the central axis. In an alternate arrangement, an outer boundary of the riser section is defined by a first wall in a plane perpendicular to a central axis, and outer boundaries of the downer section are defined by the first wall and a second wall in the plane perpendicular to the central axis. The process includes cracking the lesser boiling point fraction in the riser section in the presence of a catalyst and cracking the greater boiling point fraction in the downer reactor in the presence of the catalyst. The process includes passing the catalyst from the riser to the downer, from the downer to a regenerator, and from the regenerator to the riser.

Processes for producing petrochemical products from crude oil

Petrochemical products may be produced from a hydrocarbon material by a process that may include separating the hydrocarbon material into at least a lesser boiling point fraction and a greater boiling point fraction, cracking the lesser boiling point fraction in a first reactor in the presence of a catalyst at a reaction temperature of from 500&#xb0; C. to 700&#xb0; C. to produce a first cracking reaction product, and cracking the greater boiling point fraction in a second reactor in the presence of the catalyst at a reaction temperature of from 500&#xb0; C. to 700&#xb0; C. to produce a second cracking reaction product. The hydrocarbon material may be crude oil. The first reactor may be a riser, and the second reactor may be a downer. The catalyst may be passed from the first reactor to the second reactor, from the second reactor to a regenerator, and from the regenerator to the first reactor, such that the catalyst is circulated between the first reactor, second reactor, and regenerator. An amount of coke may be reduced on the catalyst in the regenerator.
