碩士 === 國立中正大學 === 化學工程所 === 97 === Converting C5-C9 paraffinic compounds to their corresponding alcoholic or ketonic derivatives at low temperature will increase octane number and the oxygen-containing compounds will reduce the content of benzene and aromatic hydrocarbons, it will bring huge impact to oil-refining industry. The goals of the research is to develop the crucial technique of the process. Including: (1) Synthesize highly-active titanium silicalite-1(TS-1). (2) Develop the method of quick inspecting titanium silicalite-1 activity. (3) Discuss the relationship between TS-1 function group and catalytic activity. (4) Develop the TS-1 as catalyst support for partial oxidation of paraffinic compounds. In the research and we find that: (1) The silica material and the purity of template TPAOH and the preparation method are the key point to TS-1 active site. (2) Although the characteristic peaks of X-ray Powder Diffraction can inspect whether the TS-1 is crystalline or not, infrared rays is the main instrument to inspect the fuctional group of (Ti-O-Si) bonding which is the key point to confirm the TS-1 active site. (3) In order to quickly inspect the relationship between the content of TS-1 (Ti-O-Si) bonding and catalytic properties, we synthesize different content of TS-1 (Ti-O-Si) bonding to catalyze cyclohexanone to cyclohexanone oxime. We find that the conversion of cyclohexanone and the selectivity of cyclohexanone oxime is direct proportion to the content of TS-1 (Ti-O-Si) bonding. (4) Inject nano pt metal particle into TS-1 at hydrogen-oxygen environment will convert C5-C9 paraffinic compounds to their corresponding alcoholic or ketonic derivatives. But there are acidic compounds and less total oxidation reaction in the products that will reduce the value of the process, to reduce the acidic compounds content will be the key point in the future reasearch.
