Catalyzing Commercialization
Many distributed natural-gas-containing resources, which include natural gas, landfill gas, and biogas, contain significant amounts of sulfur (mainly as hydrogen sulfide). The sulfur content in these gases, which can range from several hundred parts per million to several percent, must be reduced to acceptable levels (e.g., 1 ppm for demanding catalytic processes and several hundred ppm for internal combustion engines or boilers) before these gases can be utilized.
