Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">The catalytic dehydrogenation of cyclohexanol to cyclohexanone is an industrially important reaction. The catalysts La₂CuO₄ and strontium substituted lanthanum copper oxide Sr_0.2 La_1.8CuO_3.9 have been evaluated for their catalytic activities. They found to yield cyclohexanone in the temperature range of 573-613K beyond which dehydration is favoured. The results obtained by the flow reactor technique were fitted in different models (Langmuir-Hinshelwood mechanism) to find out the rate determining step using a non-linear least square fitting computer programme. The most suitable model was found to be a Langmuir Hinshelwood model, involving surface reaction-dual site with negligible adsorption of cyclohexanone and hydrogen.</span>
