Abstract

The application of non-edible raw materials for the production of biodiesel is an alternative to reduce costs and possible depletion of food from the application of edible oilseeds that are generally applied. For this reason, the production of biodiesel from the radish seed oil is interesting. The radish (Raphanus sativus L.) seed oil is considered non-edible due to the high content of erucic acid and has favorable characteristics for such purpose, such as high oil content, adequate composition in fatty acids and other physico-chemical characteristics. Technologies for oil extraction and ester production are addressed as resources that can sustain the production of biodiesel from inedible oils, reducing inputs and energy costs. Therefore, the objective of this work is to review the potential of the radish seed oil for biodiesel production and process intensification technologies.

Highlights

  • A exploração dos combustíveis fósseis é responsável pela emissão de CO2, além de uma variedade de poluentes do ar, como material particulado e óxidos de nitrogênio, considerados perigosos tanto para a saúde humana como para o meio ambiente

  • The application of non-edible raw materials for biodiesel production constitutes an alternative to cost reduction due to lower costs when compared to edible oilseeds, and possible food depletion

  • Oil extraction and ester production are technologies that require improvement to ensure the viability of biodiesel production, enabling the reduction of energy inputs and expenses in the production chain

Summary

Introduction

A exploração dos combustíveis fósseis é responsável pela emissão de CO2, além de uma variedade de poluentes do ar, como material particulado e óxidos de nitrogênio, considerados perigosos tanto para a saúde humana como para o meio ambiente. Este estudo abordou o potencial do uso do óleo de nabo forrageiro (Raphanus sativus L.) como matéria-prima não comestível para produção de biodiesel, incluindo técnicas de intensificação de processos e a influência das condições operacionais no rendimento em óleo.
