对开发新型硅气相催化微反催化剂的制备方法进行了实验研究。铂催化剂的催化性能可以通过调节二氧化硅层的厚度来控制。研究了氧化物载体的制备方法。采用“雾化分解法”作为催化剂制备方法，制备了环己烷脱氢硅微反应器芯片，并对不同类型铂催化剂进行了催化剂的筛选试验。采用雾化分解法考察了载体和添加剂对丁烯脱氢反应的影响。观察了氧化铝载体的促进作用。为了防止结焦失活，碱金属是有效的添加剂。在所测试的碱类中，钾是最有效的。此外，还利用具有导向性结构的反应器芯片进行了液相反应的基础研究。在水-有机双相体系中观察到了促进作用。

Experimental studies have been conducted on the development of new catalyst preparation method for gas phase catalytic micro-reactor made of Silicon. Catalytic nature of platinum catalyst was able to control by adjusting the thickness of the silica layer. Preparation method for oxide supports was also studied. Silicon micro-reactor chip was manufactured and tested by dehydrogenation of cyclohexane by using "Mist decomposition method" as a catalyst preparation method.Screening tests of catalysts has been done with micro-reactor chips with various type of platinum catalyst. Dehydrogenation of butene was conducted to test the effect of support and additives with mist decomposition method. Promotion effect of alumina support was observed. In order to prevent the deactivation by coke formation, alkaline metals are effective additives. Potassium was the most effective one among the tested alkaline.Basic study for liquid phase reaction was also conducted using reactor chip with guideline structures. Promotion effect was observed with aqueous-organic dual phase system.
