1) Does unimpregnated AC capture H2S and what would be the capacity for H2S in mg H2S/g AC?

2) The second question is regarding maximum capacity. If you imagine a system with 1 bar, temperature of 30 °C, and 70 mg/m3 of higher hydrocarbons, 300 mg/m3 of aromates (BTEX), what could you expect as a maximum capacity in mg/g? It is hard for me to believe that it can be 300 mg/g or more. More likely for me sounds max 200 mg/g.

3) Can you wash a gas with oil (boiling point 250-350 °C) and remove these fine concentrations (from question 2) to significantly lower concentrations (close to 0 mg/m3)? Or would the oil also start to vaporize and it would cause higher concentration of impurities?
