I wonder how much sulfur these adds actually remove from the surface... "just enough", which would be my impression, or "nearly all". I havent seen reproducible results of more than ~70% sulfur removal from metallic surfaces of Pd in 'real' regeneration processes.
then again, Im studying similar phenomena from a completely different angle.
A little benzene spike should be able to clean off the sulfur from Pd surfaces without issue... especially on a hot day.
How the complexation and thus cleaning works on Ag I cannot say for certain... depends on the competitive adsorption rates at ambient temperatures. Havent studied Ag to know.

yes shell did gt in trouble. someone accifdentaly, i read, turned a switch or knob, that is supposed to regualte the sulher removal form the feul, was turned off. so the sulher, contaminated the good feul. thats what i read. it was a 'human' error.
