Prevent poisoning of the hydrogenation catalyst bed.
The poisoning of the catalyst by metallic sodium in the crude oil is permanent.
Metals can deposit on the surface and within the pores of the catalyst, blocking these pores and rendering the catalyst inactive； It can also poison the catalyst and promote the formation of coke. Therefore, it is necessary to control the metal content in the crude oil
The high metal content in the crude oil affects the lifespan of the catalyst
