Abstract
The composition of gas evolved upon thermal decomposition of individual and carbamidemodified graphite nitrates was determined. The addition of carbamide was shown to result in the 2—4-fold decrease in the content of nitrogen oxides and the 2—5-fold increase in the content of carbon monoxide. The content of nitrogen oxides in the gas phase decreased when the HNO3 : (NH2)2CO molar ratio was equal to 1 : (0.4—1). Combination of carbamide addition with catalytic afterburning provides the 5-fold decrease in the gas-phase amount of nitrogen oxides at the minimum CO content.
