Entropy production model has been developed using mass, energy and entropy balances. By means of analytical derivatives it was found that a minimum of entropy production rate is reached when a particular relationship between the temperature of the inlet stream and the temperature of reaction is satisfied for a given residence time in the reactor. The results reveal the behavior and the new operating conditions, from which a higher conversion rate has been obtained when compared with the classical modus operandi.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-05-17T11:19:34Z No. of bitstreams: 1 __ac.els-cdn.com_S025527...4c7a526501314903dd535b2c373ba.pdf: 362810 bytes, checksum: c4a215015d397a02c1ddf39af6c703eb (MD5)Made available in DSpace on 2012-05-17T11:19:34Z (GMT).
