摘要： Systems and methods are provided for the conversion of methanol to gasoline. Such methods may be performed be the sequential conversion of methanol to dimethyl ether, the conversion of dimethyl ether (and unconverted methanol, if present) to an intermediate olefin-rich product, and the oligomerization of the olefin-rich product to gasoline boiling range hydrocarbons.

摘要： An FCC unit enables the normal regenerator to be eliminated by carrying out catalyst regeneration in the reactor section of the unit using air, oxygen-enriched air or even relatively pure oxygen as the stripping medium in the stripping section of the reactor while maintaining overall reducing conditions so that sulfur and nitrogen are produced in the form of hydrogen sulfide, ammonia and other reduced species. The combustion gases from the stripper are sent from the reactor with the cracking vapors to the FCC main fractionator, wet gas compressor and gas plant to process the by-products of the coke combustion along with the FCC reactor effluent. The principle is applicable to grass-roots FCC units with its potential for elimination of a major unit component but it also has potential for application to existing units to reduce the load on the regenerator or eliminate the need for the existing regenerator so that an existing regenerator may be converted to a parallel or auxiliary reactor system.
摘要翻译： FCC装置使得能够通过在反应器部分中进行催化剂再生来消除正常的再生器，所述反应器部分使用空气，富氧空气或甚至相对纯的氧作为反应器的汽提部分中的汽提介质，同时保持总体还原条件使得硫和氮以硫化氢，氨等还原物质的形式产生。来自汽提器的燃烧气体从具有裂解蒸汽的反应器送入FCC主分馏器，湿气压缩机和气体设备，以与FCC反应器流出物一起处理焦炭燃烧的副产物。该原则适用于具有消除主要单元组件的潜力的基层FCC单元，但它也具有应用于现有单元以减少再生器负载的潜力，或者消除对现有再生器的需要，使得现有的再生器可以转换为并联或辅助反应器系统。

摘要： An integrated process for converting light (C2-C5) paraffins to hydrocarbon products in the gasoline and distillate boiling range in which a light paraffin fraction is subjected to steam cracking under conditions to maximize weight of C5+ molecules plus a multiple of the weight of C4− olefins. This multiple is preferably between 0.7-1 to result in maximum volume of gasoline and distillate production in the overall conversion to products. Light (C2-C5) olefins are oligomerized in a zeolite-catalyzed fluidized bed oligomerization at elevated temperature to produce oligomerized products in the gasoline and middle distillate boiling range.

摘要： Methanol-to-gasoline (MTG) conversion may be performed with a methanol recycling. Methanol may be fed to a first reactor where it may be catalytically converted under dimethyl ether formation conditions in the presence of a first catalyst to form a product mixture comprising dimethyl ether (DME), methanol, and water. The DME may be separated from the methanol and the water and delivered to a second reactor. In the second reactor, the DME may be catalytically converted under MTG conversion conditions in the presence of a second catalyst to form a second product mixture comprising gasoline hydrocarbons and light hydrocarbon gas. The methanol and the water from the first reactor may be separated further to obtain substantially water-free methanol, which may be returned to the first reactor. The separation of methanol from the water may be performed using the light hydrocarbon gas to effect stripping of the methanol.

摘要： Systems and methods are provided for improving the integration of fluidized coking systems that include an associated gasifier with other refinery and/or chemical plant processes. The improved integration can be based on one or more types of integration improvements. In some aspects, the integration can allow for improved carbon capture. In other aspects, the integration can allow for production of higher quality synthesis gas, which can then facilitate production of various chemicals, such as ammonia or urea. In still other aspects, the integration can allow for incorporation of H2S generated during the fluidized coking and gasification into a fertilizer product. In yet other aspects, the integration can allow the fluidized coking system to continue to operate even when the associated refinery and/or chemicals production processes are off-line. In still other aspects, the integration can allow two or more of the above integration advantages, or three or more, such as up to all of the above integration advantages.

摘要： A method for upgrading olefin-containing naphtha can include injecting a hydrocarbon stream containing an olefin-containing naphtha comprising olefins and diolefins in a reforming reactor at temperatures of from about 700° F. to about 1200° F. and pressures of from about 10 psig to about 500 psig to produce a reformate stream, which is then contacted with an atmosphere comprising hydrogen in a hydrotreating reactor to produce a product stream, wherein the reformate stream comprises at least 50% less diolefins than the hydrocarbon stream and the product stream comprises at least 99% less diolefins than the hydrocarbon stream. A system for upgrading olefin-containing naphtha may include a reforming reactor configured to receive a hydrocarbon stream containing an olefin-containing naphtha comprising olefins and diolefins, which produces a reformate stream, and a hydrotreating reactor configured to receive the reformate stream.

摘要： Systems and processes are provided for upgrading a crude oil. In some examples, a heated crude oil can be introduced into an atmospheric distillation column where an overhead gas product comprising C4− hydrocarbons can be recovered and recycled back to the atmospheric distillation column to decrease the partial pressure of the C5+ hydrocarbons in the distillation column allowing higher boiling point fractions of crude oil to be vaporized and recovered.
