摘要: Favorable isomerization conditions for producing normal paraffins can produce olefins. The process for separating normal paraffins from non-normal paraffins by adsorption has a limit on olefin concentration, so the olefins must be removed. We propose to remove olefins from the isomerization effluent stream that is recycled to the adsorption separation process.

摘要: A process for treating effluent streams in a naphtha complex is described. One or more of the sour water stripping unit for the NHT sour water from the NHT, the amine treatment unit and the caustic treatment unit for the NHT stripper off-gas, the caustic scrubber unit or other chloride treatment unit for the off-gas from the C5-C6 isomerization zone and the C4 isomerization zone, and the caustic scrubber unit or other chloride treatment unit for the regenerator off-gas are replaced with a thermal oxidation system.

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 the first reactor, the first reactor being an isomerization reactor with an isomerization catalyst disposed therein to generate an isomerate stream comprising at least 20% by weight iso-paraffins. The process further includes passing the isomerate from the first reactor through a second reactor, the second reactor being an aromatization reactor with an aromatization catalyst disposed therein to generate an aromatic rich stream. The process finally includes passing the aromatic rich stream to an aromatic recovery complex to separate the aromatic rich stream into an aromatic fraction, a raffinate fraction comprising unconverted paraffins, and an aromatic bottoms fraction comprising C9+ hydrocarbons, where the aromatic fraction comprises benzene, toluene and mixed xylenes. An associated system for performing the process is also provided.

摘要: Processes and systems for the conversion of hydrocarbons herein may include separating an effluent from a moving bed reactor, the effluent including reaction product, first particulate catalyst, and second particulate catalyst. The separating may recover a first stream including the reaction product and first particulate catalyst and a second stream including second particulate catalyst. The second stream may be admixed with a regenerated catalyst stream including both first and second particulate catalyst at an elevated temperature. The admixing may produce a mixed catalyst at a relatively uniform temperature less than the elevated regenerated catalyst temperature, where the temperature is more advantageous for contacting light naphtha and heavy naphtha within the moving bed reactor to produce the effluent including the reaction product, the first particulate catalyst, and the second particulate catalyst.

摘要: Disclosed is a process for converting C2-5 alkanes to higher-value C5-24+ hydrocarbon fuels and fuel blendstocks including reacting the C2-5 alkanes in a thermal olefination reactor operating at a temperature, pressure and space velocity to convent the alkanes to olefins and in the absence of both a dehydrogenation catalyst and steam. At least a portion of the product olefin stream is oligomerized using a zeolite catalyst to crack, oligomerize and cyclize the product olefins to form the fuel products, which are then recovered. The process is useful in removing sulfur and nitrogen-based compounds in a single step process, while reducing total costs of processing and eliminating the need for additives used in the field.

摘要: A process to produce a light hydrocarbon fraction from a heavy residue feed, the process comprising the steps of operating the first supercritical reactor such that the heavy residue feed and the supercritical water stream undergo conversion reactions to produce a reactor effluent, introducing the reactor effluent to a top inlet in a top portion of a second supercritical reactor, introducing a supercritical water stream to a bottom inlet in a bottom portion of the second supercritical reactor, operating the second supercritical reactor such that the bottom of the barrel fraction is configured to settle in the bottom portion of the second supercritical reactor, withdrawing an upgraded product stream from a top outlet in the top portion of the second supercritical reactor, and withdrawing a heavy product stream from a bottom outlet in the bottom portion of the second supercritical reactor.

摘要: A reforming reactor and process of using same in which residence time of feed within a chamber of a reactor is shortened. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a baffle.

摘要: Systems for reforming a hydrocarbon feedstock, where the system is operable to selectively reform different sub-components of the hydrocarbon feedstock using at least two structurally-distinct reforming catalysts. Advantages may include a decreased rate of reforming catalyst deactivation and an increased yield of a liquid hydrocarbon reformate product that is characterized by at least one of an increased octane rating and a decreased vapor pressure compared to the liquid hydrocarbon reformate product of conventional one-step reforming systems.
