Abstract
The invention provides an improved system for separation technology intended to reduce unwanted catalyst/thermal reactions by minimizing contact of the hydrocarbons and the catalyst within the reactor.
Claims13
A process for increasing hydrocarbon yield and decreasing coke production in a fluidic catalytic cracker reactor having a separation unit, the process comprising:
- locating a bed of fluidized catalyst in the fluidic catalytic cracker reactor beneath a baffle member that is positioned proximate a bottom portion of the separation unit to reduce fluidized catalyst from entering the separation unit;
- and
- operating the fluidic catalytic cracker reactor to evacuate hydrocarbon gases from the bed of fluidized catalyst and into the separation unit.
A process for increasing hydrocarbon yield and decreasing coke production in a fluidic catalytic cracker reactor having a separation unit, the process comprising:
- positioning a catalyst bed in the fluidic catalytic cracker reactor below a baffle member that is positioned proximate a bottom region of the separation unit;
- and
- utilizing at least one vent tube to carry hydrocarbon gases from the catalyst bed, through the baffle member, and to a top region of the separation unit.
