| Abstract: | The aim of this work was to study the catalytic ethanol dehydrogenation to acetaldehyde over nickel based catalysts. SnO2, Al2O3 and SiO2 were used as supporting materials. The reactions were carried out in a catalytic flow system operated in the temperature range of 200 and 350oC under atmospheric pressure. Various parameters such as Ni loading, a kind of supporting materials, contact time on the ethanol conversion and selectivity to acetaldehyde were investigated. The main product in all cases is acetaldehyde, with secondary products such as ethyl acetate and diethyl ether. It has been found that Ni/SnO2 showed the highest ethanol conversion with high selectivity to acetaldehyde. The 10 wt% Ni/SnO2 exhibited the highest yield of acetaldehyde at 300oC with low contact time (0.05g min ml-1). The deactivation of 10 wt% Ni/SnO2 was occurred after 200 minutes on stream due to the formation of Ni – Sn alloy phase. |
| Description: | The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. |
