초록정보

Kinetic parameters for the pyrolysis of titanium tetraisopropoxide (TTIP) were measured in a constant volume batch reactor. Experimental conditions were 230℃ ~ 300℃, $2.78×10^{-7}$ ~ $1.11×10^{-5}$ mol/㎖ of TTIP concentration. The reaction can be modeled by the first order reaction. Obtained rate constants were in the range of $0.10 ~ 0.63s^{-1}$ and the activation energies spanned between 58.8 to 92.9 kJ/mol. Pyrolysis of TTIP was enhanced on the $TiO_2$ coated surface. Contribution of homogeneous decomposition of TTIP was negligible within this experimental temperature range. Effects of inert gases and oxygen atmosphere, change of reaction rate with mixing ratio of TTIP and iso-propyl alcohol were studied. Inert gases had no effect on the decomposition rate and oxygen atmosphere hindered the pyrolysis of TTIP. Iso-propyl alcohol which was present as an impurity (3 wt%) had not affected the decomposition behavior of TTIP. Results from the flow reactor were predicted with model parameter obtained from batch reactor data. Plug flow reactor(PFR) model fits better than the constant-stirred tank reactor(CSTR) model.
