Acesso restrito. p. 102–107The transesterification of waste frying oil (WFO) with methanol and ethanol was studied in a batch reactor using a zinc aluminate catalyst prepared by the combustion reaction method. The reaction runs were carried out for 2 hours, using alcohol:oil molar ratio of 40:1, temperature range of 60–200 °C, catalyst ratio of 1–10% wt., under 700 rpm stirring. The catalyst was characterized by XRD, EDX, TG, FTIR, N2 physisorption, NH3- and CO2-TPD. The catalyst showed a normal spinel structure and acid character (Lewis acid), in spite of the presence of both strong acid and base sites. Methyl and ethyl esters yields higher than 95% were obtained at 150 and 200 °C and the catalyst was recovered and reused in 3 reaction cycles, without significant loss of activity.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-07-04T17:39:27Z No. of bitstreams: 1 444444444444444.pdf: 747308 bytes, checksum: c29d3d0b79246a4ab460ace0d1385ea3 (MD5)Approved for entry into archive by Rodrigo Meirelles(rodrigomei@ufba.br) on 2013-10-09T19:47:06Z (GMT) No. of bitstreams: 1 444444444444444.pdf: 747308 bytes, checksum: c29d3d0b79246a4ab460ace0d1385ea3 (MD5)Made available in DSpace on 2013-10-09T19:47:06Z (GMT).
