Abstract
The purpose of this study is to investigate the
feasibility of the application of the catalytic
incineration to decompose polycyclic aromatic
hydrocarbon (PAH) (taking naphthalene as a target
compound, the simplest and lowest toxic PAH)
generated from the waste incineration or diesel engine
emission to atmosphere. The relationships between
conversion efficiency, operating parameters and
influential factors, such as treatment temperatures,
catalyst sizes and space velocities have been examined.
Also, the related kinetic model is proposed to describe
the reaction mechanism.
The experimental results indicate that the
catalyst used accelerates the reaction rate of
decomposition of naphthalene, and decreases the
reaction temperature. A high conversion (over 95 %)
can be achieved at the moderate reaction temperature
of 480 K and space velocity below 35000 hr-1. In
addition, the reaction temperature is a determining
factor in the catalytic decomposition. The results
indicate that Rideal-Eley mechanism and Arrhenius
equation can be reasonably applied to describe the
data by using the pseudo-fist-order reaction kinetic
equation. The activation energy (17.8 kcal/mol) andfrequency factor (3.26 × 1017 s -1) were obtained
therefore.
