COMBUSTION OF HYDROCARBONS IN SUPERCRITICAL WATER

摘要

We have studied the kinetics of benzene, naphthalene, and heavy oil residue combustion in an aqueous solution at supercritical temperatures (663 K ≤ T ≤ 1200 K) and pressures (28 MPa ≤ P ≤ 90 MPa). The oxidative combustion exhibits an explosive character and can develop according to either thermal or branched-chain mechanisms. The corresponding kinetic constants for fuels are determined and conditions for there mechanisms of benzene are established.
