Pitting corrosion and crevice corrosion in catalystdeposit zone and corrosion deposit zone can also induce stress corrosion cracking.

The metal deposit rule was depended on the patterns of the metals in crude oil and the property of the catalyst as well as the diffusion and decomposition rates of metal compounds in the catalyst.
Combining the chemical cleaning and air blasting method, this paper introduces a new method of removing the deposit resulting from the shift gas and catalyst powder, etc.
