The hydrolysis rate of organic sulfur decreases. D. The bed resistance increases
Methods to determine catalyst deactivation: A. The temperature difference between the reactor inlet and the bed temperature is small, or even the bed temperature is lower than the inlet temperature; B. A decrease in sulfur conversion rate; C. A decrease in the hydrolysis rate of organic sulfur; D. An increase in bed resistance
Determine catalyst deactivation based on (A, B, C, D)
A. The temperature at the reactor inlet is not significantly different from that of the bed; in fact, the bed temperature is lower than the inlet temperature
