What is the relationship between catalyst bed temperature and space velocity?
Thread Content
When the conversion system is in reverse gas flow, the temperature of the catalyst bed rises; in such cases, it is necessary to increase the gas flow rate and raise the space velocity. Should we still reduce the gas volume and lower the space velocity?
The gas volume should be increased and the space velocity raised to lower the temperature of the catalyst bed.
If the heat supplied remains constant and the bed temperature rises, it means that less heat is being consumed by the reaction; therefore, the space velocity needs to be increased~~
The gas guide temperature will definitely rise, and it is the most difficult temperature to control, with overheating occurring quite easily. The relationship between rising temperature and the gas flow rate follows a parabolic pattern; ultimately, experience is key. Increasing the flow rate is intended to allow heat to be removed quickly, but it may also lead to a sharp rise in temperature due to the large amount of heat generated by the reaction. As always, experience is the most important factor.
