Abstract

The reaction of hydrogen oxidation with sulfur dioxide in the region of self-ignition (T = 470–510°C and R < 200 Torr) is accompanied by the formation of elemental sulfur in an explosive mode. Kinetic calculations made with the SENKIN:CHEMKIN II program are used to analyze observed flashes of light from the explosive process, based on a mathematical model describing the oxidation of hydrogen with sulfur dioxide. Characteristics of the oxidation of hydrogen with sulfur dioxide in the region of a low-temperature chain explosion are revealed.

Keywords

sulfur dioxide, sulfur, flashes of light
