研究了利用烘箱热催化处理有机溶剂蒸汽的方法。Pt/ al2o3催化剂对甲苯具有较高的催化活性。Co3O4‐ceo2催化剂优先氧化乙酸乙酯和乙酸丁酯，但产生副产物。这些有机溶剂在日本的绘画和印刷油墨中产生高排放量。然而，在低温下同时处理这三种溶剂是困难的。在本研究中，当Pt/Co3O4‐ceo2催化剂在230-250℃的烘箱温度下使用时，可以有效地处理含有甲苯、乙酸乙酯和乙酸丁酯的气体，而不会积碳。Pt/Co3O4‐ceo2催化剂的应用使得利用烘箱自身的热量在烘箱中进行处理成为可能。
A catalytic treatment for organic solvent vapor using the heat of a baking oven was investigated. A Pt/Al2O3catalyst showed high activity for toluene. A Co3O4‐CeO2catalyst preferentially oxidized ethyl acetate and butyl acetate, but by‐products were generated. These organic solvents produce high emissions from painting and printing ink in Japan. However, treating all three solvents simultaneously at low temperatures is difficult. In the present study, when a Pt/Co3O4‐CeO2catalyst was employed at oven temperatures of 230–250 °C, a gas containing toluene, ethyl acetate, and butyl acetate was able to be effectively treated with no carbon deposition. The application of the Pt/Co3O4‐CeO2catalyst enabled treatment in the oven using the oven's own heat.
