Does the 3 dry gas, as a product, affect the reaction within the reactor? 4 Does the amount of dry gas affect the space velocity, and does it also influence the reactions within the reactor?
Reaction and regeneration – what exactly do you want to ask?

The role of dry gas is primarily to suppress the reaction; it can quickly remove heat from the bed, thereby reducing the temperature difference within the bed and preventing the catalyst from overheating. Towards the end of the reaction, the amount of dry gas increases
1. The function of dry gas is to inhibit the polymerization and coking of olefins, as well as to prevent catalyst coking. 2. The amount of dry gas typically accounts for 1–3% of the feedstock; at the beginning of the reaction, when the catalyst’s activity is high, a larger amount of dry gas can be used to control the temperature of the reaction bed. 3. The amount of dry gas is determined based on the level of olefins in the feedstock, as dry gas acts as an inert component that can reduce the olefin content in the feedstock, thereby helping to control the temperature of the reaction bed. 4. With advancements in catalyst technology, it is now possible to do without circulating dry gas; adjustments should be made accordingly depending on the type of catalyst used
