Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h. The space velocity of the reactor catalyst is 500 h-1. Therefore, () tons of catalyst need to be installed, with a catalyst density of 800 kg/m3
Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h. The space velocity of the catalyst in the reactor is 500 h-1; therefore, (3.75) tons of catalyst are required. The density of the catalyst is 800 kg/m3
Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h. The space velocity of the catalyst in the reactor is 500 h-1; therefore, (2.67) tons of catalyst are required. The density of the catalyst is 800 kg/m3
Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h. The space velocity of the reactor catalyst is 500 h-1; therefore, (5.28) tons of catalyst are required. The density of the catalyst is 800 kg/m3
It hadn’t been calculated before; it was unclear whether the air velocity values referred to standard conditions or those under actual operating conditions. After reviewing the design parameters of our device, it was generally confirmed that standard conditions should be used. 3300/500=6.6 cubic meters, 6.6*0.8=5.28 tons.
Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h; catalyst space velocity in the reactor: 500 h-1; a catalyst amount of (5.28) tons should be used
The Klaus exhaust gas flow rate is 3000 m3/h, with a hydrogen supply of 300 m3/h; the space velocity of the catalyst in the reactor is 500 h-1. Therefore, (5.28) tons of catalyst are required, given that the density of the catalyst is 800 kg/m3
Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h. The space velocity of the reactor catalyst is 500 h-1; therefore, (5.28) tons of catalyst are required. The density of the catalyst is 800 kg/m3
5.28t:time::time::time::time:
Klaus off-gas: 3000 m3/h; hydrogen supply: 300 m3/h. The space velocity of the catalyst in the reactor is 500 h-1; therefore, (8) tons of catalyst are required, with a density of 800 kg/m3
The correct answer is 5.28t; for the detailed calculation process, see floor 5.
