Therefore, the aims of this work were: a) to study, by means of
experimental design and analysis of variance (ANOVA), the influence
of mixtures of waste fish oil, palm oil and waste frying oil as feedstock
on the fuel characteristics of the biodiesel obtained, b) to obtain, by
means of response surface methodology, the feedstock mixture that
optimizes viscosity, oxidative stability and cold flow properties of the
biodiesel produced, and c) to determine, by means of multi-objective
optimization, the feedstock mixture that optimizes simultaneously the
fuel properties of the biodiesel samples.
