摘要：
The invention provides a method for removing mercury from a liquid or gas hydrocarbon stream, mixtures thereof, including mixtures of liquid streams with a solid carbonaceous substance, by contacting the hydrocarbon stream with a composition comprising silver and a support material, wherein the composition as measured by ammonia chemisorption has a surface acidity in the range of 0.1-10.0 μmole of irreversible NH3/g of the composition.
