AI Technical Summary
The support structure of traditional fixed-bed hydrogenation reactors is not stable enough, which makes the catalyst plates and flow dividers prone to displacement, affecting reaction efficiency and maintenance difficulty; uneven pretreatment of raw materials affects catalyst activity and reaction efficiency.
The catalyst plate and the flow divider are stably supported by positioning components and connecting ring pipes. The raw materials are uniformly dispersed and heated by the ring distribution plate and heating pipes, ensuring that the gas is evenly distributed on the catalyst plate.
It improves the stability of the reactor's internal structure, ensures full utilization of catalyst activity, avoids excessive or insufficient local reactions, and simplifies equipment maintenance.
