The improvement included: (1) reuse of CALB in the presence of ethanol (EtOH), (2) reuse of CALB in the presence of methanol (MeOH), (3) blended alcohols at di ff erent molar ratios (0:100, 20:80, 40:60, 50:50, 60:40, 80:20 and 100:0, %EtOH:%MeOH), and employing second generation raw materials: waste cooking oil (WCO) and castor oil (CO). When the first strategy was carried out the FAEE (fatty acid ethyl ester) content achieved was 96% in a first cycle but after four cycles the percentage decreased to 32%. For the second strategy the FAME (fatty acid methyl ester) content attained was 63% in a first cycle but after four cycles the percentage was only 13.5%. When the blended alcohols were tested, the negative e ff ect of MeOH was evident for higher concentrations regardless the type of oil used. | URI: | http://ri.uaemex.mx/handle20.500.11799/97281 | Other Identifiers: | http://hdl.handle.net/20.500.11799/97281 | Rights: | info:eu-repo/semantics/Revista Mexicana de Ingeniería Química info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
