  • HAUG Decomposition

    HAUG Decomposition. Jan 22, 2013The stoichiometric demand for oxygen can vary from about 1.0 g O2 /g BVS for highly oxygenated feedstocks like cellulose or starch to 4.0 g O2 /g BVS for some hydrocarbons (Haug, 1993). Because air contains 23.2 percent oxygen by weight, the air demand is the oxygen demand divided by 0.232.
