①Low air velocity, long residence time, and intense hydrogenation reactions can easily lead to difficulties in controlling the bed temperature； ②Too low an air velocity increases the likelihood of condensation reactions, leading to coking on the catalyst surface ； ③Too low an air velocity results in a higher content of light components in the products, especially an increase in the amount of gas ； ④Too low an air velocity can cause channeling in the reaction bed ； ⑤When the feed rate is too low, it becomes more difficult to operate the distillation system.
One additional point: The relatively large proportion of heat dissipation from the outer surface of the heat exchanger leads to increased energy consumption of the device
Reply to 1# lgc1986: Is it the feed rate that is too low, or is the feed temperature too low?
