In general, the characteristics of stone are two: high regenerative thermal activity and low cost. In this study, isopropyl alcohol (IPA) was oxidized by metallic catalysts with stones as carriers. To discover the best removal efficiency of isopropyl alcohol, different catalysts with different ratios of metal (these metals were copper, manganese, and cobalt) and different loading (loading meant the ratio of the weight of metal to the weight of stone) were made. Moreover, others parameters such as different inlet concentration of IPA, inlet concentration of oxygen, space velocity, reaction temperature, and long-term test were also discussed. Finally, two kinetic models were introduced to prove the catalytic oxidation mechanism of IPA. The experimental results showed that the most effective catalyst is copper-cobalt catalyst, which ratio of metals is 6: 4 and loading is 10%. With this kind of catalyst, the optimal operational parameters could be easily found, and they were as follows: the inlet concentration of IPA was 1500 ppm, space velocity was 13500 hr-1, and reaction temperature was 350¢J. It was noticed that the conversion of IPA was all up to 95% in these conditions. In conclusion, the experimental results also indicated that conversion was increased with reaction temperature, inlet concentration of IPA and inlet concentration of oxygen increasing. On the contrary, the conversion was decreased as space velocity was increased. Besides, after long-term test of catalyst, the results showed that the performance of the catalyst acted still fairly well in oxidation. To realize the physical properties of catalysts, some analytic instruments such as SEM, EDS, EA, XRD were used. These analytic results could also tell us the difference between fresh and aged catalysts. Two kinetic models, Power rate law Model and Mars-Van Krevelen Model, were used to fit the kinetic mechanism of the decomposition of IPA. The fitting result was that Power rate law Model was rather suitable to describe the catalytic decomposition of IPA in the operational conditions in this work, and the reaction order was nearly first order.

The nature and scope of this problem is to determine from the irradiation of isopropyl alcohol with 2537 A, the behavior and mechanism of the reaction, since it is known that a reaction does occur.

ABSTRACT Isopropyl Alcohol (denoted as IPA) is a valuable chemical product, which is used in the chemical industry such as synthetic resin, essential oils and surface paint. Moreover, factory of the production of photography and electronics are also the user of IPA.IPA is the typical pollutant emitted from those industrial processing . It is known to be causing severe irritation and burns and is suspected to have long-term effects such as bronchitis. This study was to investigate the effect on conversion, deactivation of long-term test, selectivity of product and kinetics in oxidation of IPA over Cu and Cu/Ce catalysts supported on ceramic honeycomb. The explanation of results can be divided into several major parts as follows: 1. In the of selection catalyst, we find that 20%Cu/Ce catalysts prepared by wet- impregnation has the best conversion and selectivity. 2. The conversion of IPA in catalytic reaction is increased with the increasing both of reaction temperature and influent concentration of oxygen but decreased with the going up of initial concentration of IPA, space velocity and relative humidity. 3. In the catalyst stability of long-term test, Cu/Ce catalysts had a good stability after 7 days reaction in heterogeneous reactor. The tests such as XRD, SEM and EA were also determined to verify the stability from surface of catalyst. 4. Two kinetic models, Power rate law and Mars-Van Krevelen model were used to fit the kinetic data of the decomposition of IPA. Power rate law is suitable to describe the catalytic decomposition of IPA under the operation range in this work.
