Apr.Chromium and potassium-doped iron oxides are widely used as industrial catalysts in the dehydrogenation of ethylbenzene to produce styrene. They have several advantages but deactivate with time, because of the loss of potassium. Also, they are toxic due to chromium compounds. Therefore there is a need for developing alternative non toxic catalysts without potassium. Then, iron and aluminum compounds were prepared by different methods in this work. Different phases were produced depending on the preparation method. Aluminum-doped hematite was more active and selective to styrene than the aluminum ferrite. Aluminum acts both as textural and structural promoter in the catalysts.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-19T09:30:37Z No. of bitstreams: 1 14984.pdf: 1177523 bytes, checksum: ead245e8a603d83de92ae4cbc5a140f9 (MD5)Made available in DSpace on 2011-12-19T09:30:37Z (GMT).
