The book "Technologies for Biodiesel Production" offers a comprehensive analysis of the technologies used to produce biodiesel, a sustainable and renewable fuel derived from vegetable oils or animal fats. In light of growing environmental concerns and uncertainties associated with fossil fuels, the development of efficient and eco-friendly production methods is becoming increasingly important. The authors, Fernando Pessoa and Eduardo Queiroz, highlight common processes, particularly alkaline homogeneous catalysis, and present innovative approaches such as supercritical production and enzymatic catalysis. Through simulations of biodiesel production from soybean and Dendê oils, the advantages and disadvantages of the various technologies are examined. This technical book is aimed at students and professionals interested in process simulation and engineering in the field of renewable energy.
