- •
The anions binding with the alkali metals can affect the poisoning profile.
- •
HOMO energies can be used to determine the poisoning strength of various compounds.
- •
MOH, MCl and MNO3 produce volatile species for the anions after poisoning.
- •
M2SO4 and MHSO4 will leave both cations and anions on the catalyst surface.
