Petroval  Dense Loading And Reactor Pressure Drop

Petroval Dense Loading And Reactor Pressure Drop

Introduction since dense loading reduces the void space within a catalyst bed it is unavoidable that the bed pressure drop dp will increase this increase is quite significant of the order of about 80 for a dense loaded bed of extrudated catalyst compared to a sock loaded bed of the same catalyst
