How is the reactor space velocity calculated?
Please consolidate questions of the same type into one post
Air velocity includes volume air velocity and mass air velocity; generally, volume air velocity is used. The calculation method is to divide the volumetric flow rate of the feed by the volume of the catalyst packed in the reactor!
Shouldn’t the air velocity be calculated by dividing the feed rate by the reactor’s cross-sectional area? The unit for this value should be m/s, and that way, the residence time can also be determined. Of course, you also need to take into account the effect of temperature on the gas velocity, as well as the resistance in the catalyst layer. What I mentioned earlier refers to a tube without a catalyst.
