Changes in the amount of catalytic dry gas?

This change is relatively small, after all, the increase in the pre-heated dry gas volume is not significant. Increasing the dry gas volume in advance has two effects: one is that it increases the dry gas volume, which in turn raises the dry gas volume at the stabilization unit. On the other hand, the amount of dry gas entering the lift pipe increased, which reduced the extent to which the reaction proceeded in the direction of generating dry gas; this in turn decreased the amount of dry gas produced by the reaction. However, when the amount of pre-lifted dry gas is normal, there is a certain quantity that already suppresses the formation of dry gas to some extent; therefore, an increase in this pre-lifted dry gas has a limited effect on suppressing dry gas formation. Overall, the amount of dry gas entering the stable system will increase slightly. However, the increase in the pre-heated dry gas volume is limited; if the increase is too large, the catalyst residence time becomes too short, which affects the reaction.
