What are the general principles for increasing temperature and dosage in catalytic reforming?

Is it generally to increase the temperature first and then the amount, or to decrease the temperature first and then the amount?
Generally, the amount is increased first and then the temperature is increased; the amount is decreased first and then the temperature is decreased
Increase the volume first before raising the temperature; decrease the volume first before lowering the temperature
Increase the temperature first by increasing the volume; decrease the volume first by lowering the temperature
It seems that this is the case for many chemical processing units: first increase the volume before raising the temperature, and first reduce the temperature before decreasing the volume, in order to protect the catalysts and equipment
Increase the volume first and then the temperature; decrease the temperature first and then the volume. This is correct; the root should first have its volume increased and then its temperature raised, in the opposite order.
During normal production, increase the volume first and then raise the temperature; when shutting down, lower the temperature first and then reduce the volume
Increase the volume first, then the temperature. Cool down first, then reduce the amount. Doing this will cause the actual temperature to be lower than the set temperature during the operation, but the impact is minimal. Safety is the most important thing. If the temperature is increased first, it may cause the reaction temperature to rise too high, which is detrimental to the catalyst and hinders the reaction.
Generally, the amount is increased first and then the temperature is increased; the amount is decreased first and then the temperature is decreased
Is it generally to increase the temperature first and then the amount, or to decrease the temperature first and then the amount?
When raising the temperature, increase the amount first; when lowering the temperature, decrease the amount first – this is mainly to protect the catalyst
