AI Technical Summary
Low mass transfer efficiency, difficulty in catalyst regeneration, and uneven temperature control are problems existing in current cracked gas catalytic cracking units, which affect operational stability and economy, especially in small and medium-scale production scenarios.
The gas-solid contact path is extended by using the swirling effect, and the catalyst carrier plate is quickly disassembled and assembled by using the limiting slot and top bead structure. Combined with the baffle plate to enhance countercurrent heat exchange, the catalyst can be regenerated online and the temperature is controlled.
It improves gas-solid contact efficiency, simplifies catalyst replacement process, reduces downtime, lowers energy consumption, and enhances reaction uniformity and production efficiency.
