| Summary: | 碩士 === 長庚大學 === 化學工程研究所 === 89 === The objective of this research is to produce the high performance catalyst applied in conversion of CO2 to CO by catalytic hydrogenation. This experiment uses Cu-based catalyst as basis, altering the reaction temperature、reduction temperature、different additives and else condition to find out the optimal catalyst and reaction conditions.
The results show that the conversion of CO2 have correlation with the copper surface area of catalysts and different additives。The activity of Cu-based catalysts decreases seriously with long reaction time at high temperature. On the other hand, a small amount of Fe in Cu catalyst has been successfully developed to improve the Cu-based catalyst in activity and stability of catalyst at 600℃ with 120hr. The results, show that the copper surface area of Cu-Fe catalyst don’t decrease very much because of adding Fe into Cu-based catalyst can diminish the catalyst surface to sinter.
The addition of potassium is greatly enhancing the catalytic activity of Cu-based catalyst because of adding small amount potassium in to Cu-based catalyst can enhance the adsorption of CO2 on catalyst surface.. On the hand, there will be a new active site at Cu/K interface to improve reaction.
