摘要： A process and apparatus for fluid catalytic cracking (FCC) of a hydrocarbon feed. The process and apparatus includes a riser which upwardly discharges into a deflector baffle located within a stripping vessel. The stripping vessel is located within a disengaging vessel. The deflector baffle is spaced from the riser and the stripping vessel. Preferably, the deflector baffle is shaped similarly to a large bubble cap. Catalyst passes downwardly from the baffle into a stripping zone within a lower portion of the stripping vessel. Hydrocarbons stripped from the catalyst pass upwardly aaway from the stripping zone, then pass to a cyclone located outside the stripping vessel and then discharge from the disengaging vessel.

摘要： In a method and apparatus for improving the flow of catalyst particles from a riser conversion zone to a separator in a fluidized catalytic cracking (FCC) unit, the exit of the riser conversion zone is equipped with a deflector mounted so as to redirect catalyst particle and gas suspension movement toward a separator inlet, thus preventing rebound back into the riser conversion zone. The catalyst deflector can be combined with one or more of a short contact time stripper, a stripper mount in or adjacent the exhaust barrel of a separator, and/or a catalyst seal pot, all serving to reduce "residence" time of hydrocarbons with catalyst particles.

摘要： In the conversion of light olefins to heavier hydrocarbons, an improved recovery technique is provided for selectively removing unreacted light olefins from a catalytic reactor effluent. This system is useful in converting ethene-rich feedstocks to gasoline and/or distillate products, particularly in oligomerization processes employing shape selective siliceous catalysts such as ZSM-5 type zeolites. By recycling gasoline-range hydrocarbons as a sorbent liquid, unreacted C.sub.2.sup.+ components may be absorbed from reactor effluent vapor and returned for further contact with the catalyst.

摘要： A catalytic process for converting an olefinic feedstock comprising lower olefin to heavier hydrocarbon product comprising the steps of:contacting the feedstock and a recycled hydrocarbon with shape-selective zeolite oligomerization catalyst in catalytic reaction zone at elevated temperature and pressure to provide a heavier hydrocarbon effluent stream comprising heavy, intermediate and light hydrocarbons;flashing the effluent stream between the reaction zone and a phase separation zone by reducing pressure of the effluent stream, thereby producing a heavy liquid stream rich in heavy hydrocarbons and a flashed effluent vapor stream containing lighter hydrocarbons;separating and recovering a recycle stream rich in intermediate range hydrocarbons from the separation zone and pressurizing the recycle stream for recycle to the reactor inlet;further fractionating the heavy liquid stream and flashed effluent vapor from the phase separation zone in first distillation tower to remove light hydrocarbons therefrom; andrecovering substantially all of the heavy hydrocarbons produced in the reaction zone in a fractionated liquid product stream.
