Why is it necessary to pass air through the catalyst in the reforming isomerization section to activate it?
Thread Content
The catalyst is already in an oxidized state; then how is it activated by introducing air?
The active component (metal) on the catalyst carries out oxygen-enriched dispersion
After dispersing the metal crystals in an oxygen-rich environment, we replaced the gas with nitrogen and then with hydrogen; after raising the temperature to 130 degrees, oil was introduced. I don’t understand why the metal components of the catalyst must be in their elemental form in order to be active – can hydrogen replacement after oxidation still serve a catalytic role?
Is ventilating it causing burning? Remove carbon
The purpose of introducing air is to burn the carbon-containing substances attached to the surface of the catalyst, producing water and carbon dioxide; this process also allows the pores in the catalyst to become exposed, thereby increasing its surface area. This is generally divided into primary burning and cleaning burning
