A fluidized catalytic reactor connected to a start-up heater is provided. The start-up heater provides sufficient heat to a catalyst containing stream to gradually increase the feed temperature. This allows for a critical volumetric flow rate to be achieved so that catalyst can be recovered from product instead of being entrained in product.

Process and apparatus for reacting feed with a fluidized catalyst with a reduction in catalyst loss during startup

An apparatus comprising a feed distributor comprising a side cluster of orifices instead of or in combination with an end cluster of orifices for distributing hydrocarbon feed into a catalyst stream. A side cluster of orifices in conjunction with an end cluster of orifices on a feed distributor can distribute hydrocarbon feed into a riser over a greater cross-sectional extent enabling emission of smaller droplet sizes which provide better conversion with less coke production.

Apparatus for distributing feed with a cluster of orifices on a side of the distributor

Vent gases from a catalyst cooler are directed downstream or outside of the catalyst regenerator to avoid sending air to a location where after burn may occur. Vent gases contain oxygen that when contacted with carbon monoxide in regenerator flue gas can cause after burn to occur at a location which lacks sufficient catalyst density to serve as a heat sink. Locating the cooling media supply in the top of the catalyst cooler enables cooled catalyst to drain from the bottom of the catalyst cooler and fitting more cooler tubes in the catalyst cooler.

Catalyst regneration with inverted cooler

An oxygen gas stream is distributed to a spent catalyst stream through an oxygen nozzle of an oxygen gas distributor and a fuel gas stream is distributed to the spent catalyst stream through a fuel nozzle of a fuel gas distributor. An oxygen gas jet generated from said oxygen nozzle and a fuel gas jet generated from said fuel gas nozzle have the same elevation in the regenerator. In a regenerator, an oxygen gas distributor and a fuel gas distributor may be located in a mixing chamber. A fuel outlet of a fuel nozzle of the fuel gas distributor may be within a fifth of the height of the mixing chamber from an oxygen outlet of an oxygen nozzle of the oxygen gas distributor. In addition, clear space is provided between a fuel gas nozzle on a fuel gas distributor and a closest oxygen nozzle on an oxygen gas distributor.

Process and apparatus for distributing fuel and air to a catalyst regenerator

In an apparatus for fluid catalytic cracking a riser having a top and a bottom for fluidizing and cracking a hydrocarbon feed stream by contact with catalyst exits an outlet at the top of the riser. A downer in communication with the outlet of the riser receives cracked hydrocarbon product and catalyst. A swirl duct in communication with the downer has a discharge opening below the outlet for discharging said cracked hydrocarbon product and catalyst. A stream of hydrocarbon feed and a catalyst is passed upwardly in a riser. A stream of gaseous hydrocarbon products and catalyst is directedly downwardly and then the stream of gaseous hydrocarbon products and catalyst are directed to flow in an angular direction to separate gaseous hydrocarbon products from the catalyst.

Riser extension apparatus and process

A fluid catalytic cracking (FCC) process for cracking multiple feedstocks in a FCC apparatus comprising a first set of feed distributors having first distributor tips and a second set of feed distributors having second distributor tips is provided. A first feed is injected into the riser from first distributor tips. A second feed is injected into the riser from second distributor tips. The first distributor tips and the second distributor tips are positioned at different radii in the riser. The first feed and the second feed are cracked in the riser in the presence of an FCC catalyst to provide a cracked effluent stream. The first distributor tips and the second distributor tips are located into a region of lower catalyst density and a region of higher catalyst density respectively in the riser.

Fluid catalytic cracking process for cracking multiple feedstocks

In an FCC apparatus and process structured packing should be located at the very top of the stripping section in an upper region. The lower region below the structural packing may be equipped with fluidization equipment such as stripping media distributors and one or more gratings. This arrangement enables stripping of entrained hydrocarbons off the incoming catalyst immediately upon entry into the stripping section allowing the entrained hydrocarbon to exit the stripping section with minimized residence time to minimize post-riser cracking. Revamp of stripping sections with tall stripping sections should conducted in this way to improve performance and reduce down-time for equipment installation.

Apparatus and process for separating gases from catalyst and revamp

Pyrolysis methods and apparatuses that allow effective heat removal, for example when necessary to achieve a desired throughput or process a desired type of biomass, are disclosed. According to representative methods, the use of a quench medium (e.g., water), either as a primary or a secondary type of heat removal, allows greater control of process temperatures, particularly in the reheater where char, as a solid byproduct of pyrolysis, is combusted. Quench medium may be distributed to one or more locations within the reheater vessel, such as above and/or within a dense phase bed of fluidized particles of a solid heat carrier (e.g., sand) to better control heat removal.
