(OP)
What are tolerable levels of Hydrogen Sulfide in Fuel? I am planning to run a natural gas automotive engine on BioGas.
To do so, I will be making a scrubbing system to remove H2S and CO2 from BioGas, but I need to know how much H2S an engine will tolerate. Any help, any references would be most helpful!

One note that surfaced, exhaust catalysts showed some significant amount of regeneration when the sulfur levels were removed (from 160ppm to 40 ppm). Also of worthy comment, this was using gaseous fuels.

If it does burn, it produces quite strongly acid byproducts. I would think you want very low concentrations, but I have no idea for actual numbers.
Franz's data suggests less than 160 ppm as sulphur as the max., but 40 ppm as quite acceptable.

So since your question was about what level can the engine tolerate, the legal limits on 'natural gas' are irrelevant.
The engine won't know whether it is being used in a car or a hog-farm power generator. So the comments in here will still apply....
