that the maximum predicted pressures for thermodynamic model are about 71.3×105 Pa and 79.79×105 Pa, and for chemical kinetic model, they are about 71.48×105 Pa and 78.123×105 Pa, fairly comparable... temperature and pressure. Moreover, the maximum temperature and pressure are associated with richer mixtures. Key words: HCCI engine; ethanol; two-step reaction mechanism model; chemical kinetic model......

of the second DTG peak. Four n-order kinetic models of Coats-Redfern, Ozawa, Kissinger and Freeman-carroll were used to get the kinetic parameters. Furthermore, a novel "two-step four-reaction model... of deviation among kinetic values were tried to be elucidated. The new established model could more satisfactorily describe the pyrolysis process of MTT, being more mechanistic and conveniently serving......
of ore-particle during the leaching process, and then accelerate the leaching process. A kinetics model of leaching reaction intensified by ultrasonic wave was established by introducing intensified reaction rate constant Kc. The leaching mechanism intensified by ultrasonic wave was analyzed according to the kinetics models. Key words: chalcopyrite; leaching; ultrasonic wave intensifying; kinetic......
data provide an excellent fit to Langmuir isotherm model. The results of the kinetic studies show that the rate of adsorption follows the pseudo-second order kinetics.
