Abstract

Nowadays, the fossil’s fuel reserves have reduced, causing an increase on the oil’s derivate prices. Thus, the biodiesel appears as an alternative, where the oil of canola is a source to this biofuel, which has from 40% to 46% of oil in grain and showed an excellent quality, due to be constituted of fat acids. This work presents physicochemical properties of canola's biodiesel produced from methylic and ethylic routes through the transesterification process. The results are in according to the established by National Agency of Petroleum, Natural Gas and Biofuels (ANP).

Highlights

The fact that the world remains very dependent on oil still coming up as a big concern, based on current forecasts that, in the near future, the main oil reserves may become extinct [2, 3]

The canola oil used in this study had an acid number of 0.40 mg KOH/g (Table 2)

Summary

Introduction

The fact that the world remains very dependent on oil still coming up as a big concern, based on current forecasts that, in the near future, the main oil reserves may become extinct [2, 3]. There are environmental and public health issues related to the combustion of fossil fuels. The combustion of fossil fuels leads to the emission of large quantities of CO2, the main greenhouse gas [4]. Hoffman et al showed an increase in the average concentration of CO2 and other greenhouse gases in recent decades [5]. The concentration of CO2 in the atmosphere has increased at a rate of 1.6 ppm.year-1, from 1974 to 2004, as a result of human activities, such as fossil fuel consumption [4, 5]. In addition to greenhouse gases, the burning of fossil fuels leads to the emission of sulfur dioxide (SO2) and particulate matters consisting of powder and ash suspended in the flue gas [6, 7]. Considering the changes in local biodiversity, these pollutants cause various ills to human health, such as respiratory disorders, allergies, degenerative lesions to nervous system and vital organs, cancer etc
