    摘要: The present invention is an improved design and operation of a short contact time Fluid Catalytic Cracking (FCC) Reactor wherein the upper internal riser and a lower internal riser are in fluid connection with one another and provide an improved disengaging zone for entraining the vapors from the dilute phase area of the FCC reactor. Detailed preferred embodiments include improvements over the prior art to the internal central riser, riser termination apparatus, cyclone separators, and a coke mitigation baffle system, as well as associated improved fluid catalytic cracking processes utilizing the novel reactor design.

    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: 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: Systems and methods are provided for conversion of light paraffinic gases to form liquid products in a two-stage reaction system. In a first stage, the light paraffinic gas is exposed to heat transfer particles in a side riser, where the heat transfer particles correspond to particles used in a separate process. Examples of a separate process include fluidized coking and fluid catalytic cracking. The conditions in the side riser can be selected to allow for conversion of at least a portion of the paraffins to olefins. After conversion, the converted olefin stream is passed to the second reaction stage while the heat transfer particles are returned to the separate process. The converted olefin stream is then exposed to a conversion catalyst under conditions for forming aromatics from the converted olefin stream in a second reaction stage. By performing the initial alkane conversion to olefins in the first reaction stage, the amount of coke formed during the aromatics formation process is reduced or minimized.
