Gas Phase Reactions of Hydrogen Peroxide and Hydrogen Peroxide/Methanol Mixtures with Air Pollutants

摘要

Hydrogen peroxide and its mixtures with methanol are capable of removing multiple air pollutants, NO, SO_3, and carbon-containing compounds from combustion-generated flue gas. Chemical kinetic calculations and experimental data demonstrate that hydrogen peroxide can be injected into flue gas at temperaturesof 700-1100 K to convert unreactive NO and corrosive SO_3 to NO_2 and SO_2. Nitrogen dioxide is much more reactive than NO and can be removed downstream simultaneously iwth SO_2 by wet or dry scrubbing systems that are currently required for SO_2 control. Hydrogen peroxide also promotes the oxidation of organic compounds to Co and Co-2 and the oxidatio fo CO to CO-2.
