Abstract
Analysis of environmental issues linked to the thermal treatment of ammunition was carried out. An opportunity to purify ventilation emissions from thermal treatment furnace using a sorbent and deep oxidation catalyst was explored. The activity of a series of complete oxidation catalysts based on transition metal oxides, and also platinum and palladium was investigated. It was determined that Pt-Pd/5 % CeO2-Al2O3 catalyst displayed the highest activity. A technology was suggested and a plant to dispose of ventilation emissions from the thermal utilization of sub-standard ammunition (cartridges, casings, and small arms primers) was developed. The technology includes removal of vapours of mercury, lead, nitrogen oxides, and other inorganic impurities from the gases on a sorbent and CO oxidation over a solid catalyst.
