Study on Chemical Kinetics of Explosion Caused by Pentane Leakage

Air–light
hydrocarbon mixing gas with pentane as the main
component is recognized as the “fourth urban gas” by
the Chinese government. However, leakage may occur because of inadvertent
human operation, and in this case, it is very easy to cause explosion.
This paper mainly studies the changes in reactants, products, and
free radicals during the explosion of pentane, especially the effects
of oxygen and carbon monoxide concentrations on human body in this
environment. In actual situations, excessive leakage of pentane is
predominant. Once an explosion occurs, oxygen will be quickly consumed,
and the concentration of carbon monoxide will rise abruptly. The high
temperature resulting from the explosion can cause carbon dioxide
to rarely react with carbon atoms to form carbon monoxide through
the reaction of CO2 + C = 2CO. The research studies on
the three major free radicals including hydrogen radical, oxygen radical,
and hydroxyl radical are performed to provide theoretical support
for preventing the chain reaction from further expanding the impact
of explosion.
