Abstract
As an improvement to processes for desulfurization of natural gas and synthetic natural gas streams that employ conventional zeolitic materials (absorbents), including copper-containing zeolites, pre-treatment methods and post-treatment methods are provided that lower the level of leachable benzene following desulfurization with the absorbents to <0.5 mg benzene/L leachate, while retaining within the absorbents a majority of sulfur adsorbed from a gas stream.
