Biodegradation of polyurethane derived from castor oil
(Associação Brasileira de Polímeros, 2014)
Castor oil preheater selection based on entropy generation and exergy effectiveness criteria
Castor oil has an especial hydroxyl fatty acid (cis-12-hydroxyoctadeca-9-enoic acid) which provides
unique properties and unusual versatility as a raw material for biodiesel production. Heating and
pumping are the major ...
