Brazil is a major producer and consumer of biodiesel, and approximately 80-85% of that biodiesel is from soy. A number of government initiatives have been taken to encourage biodiesel production from feedstocks that do not compete with food production. We report here on biodiesels prepared from cotton, licuri, dende, mamona and cocoa residues, among others.The molecular composition of these fuels has been characterized and their oxidative stability has been measured using the Rancimat test (EN14112). Relationships between biodiesel molecular composition, oxidative stability, and cetane number will be discussed.
