The book explains that an increase in the fresh feed rate leads to a decrease in the bed temperature. Could you explain this statement?

The book states that as the amount of fresh feed increases, the bed temperature decreases. What is the reason for this?
This means that, with all other operating parameters remaining unchanged, if the reaction feed rate suddenly increases, the temperature at the exit of the reaction heater drops, which in turn leads to a decrease in the temperature at the reactor inlet. As a result, the reaction depth decreases, and the bed temperature falls as well.
The amount of feed passing through the catalyst per unit time increased, while the reaction depth decreased
An increase in feed volume leads to an increase in space velocity, resulting in a reduction in reaction time; this has a significant impact
At low air velocity, the reaction depth decreases, causing the bed temperature to drop temporarily; if the outlet temperature of the furnace is kept constant, the bed temperature may rise again. The book says hydrogenation refining; it’s hard to say for the cracking agent
