Summary : Vegetable oils used as fuel for Diesel engines are the object of an increasing interest in sectors like agriculture, electricity generation or transportation, in Southern countries as much as in Northern countries. The recent directive of the European Parliament and the Council of the European Union clearly expresses the will to promote the use of biofuels for transportation from 2005 onwards. Equipments and machines adapted or designed for the use of biofuels including vegetable oils should soon be launched on the market. In a context of high and increasing oil prices, we can wonder about the energy opportunities of cotton oil whose yield per hectare varies between 100 and 300 litres according to the site. Previous works and some applications started since the end of the 1980s show that cotton oil used as biofuel presents the same behaviour as rapeseed oil or sunflower oil used more and more massively in Europe. Technical constraints of use are pointed out for engines as well as burners. If equipments are adapted, performances and efficiencies are very close, sometimes better, than those of petroleum products. Pollutant emissions are also identical with the advantage that vegetable oils do not reject fossil CO
2 in the atmosphere. Two examples of use in Africa, since 1988, of cotton oil as biofuel are mentioned. |
