摘要

Biodiesel is a fuel obtained from biomass that can be used in diesel engines, either pure (B100) or blended with mineral gasoil (Bxx), with advantages in terms of emissions and engine erosion. The biodiesel molecular structure, consisting of linear esters, allows similar physical-chemical properties compared to mineral diesel oil. Some important properties of the oil, such as viscosity, melting point, thermal stability and cetane index can be directly related to the chemical composition of the biomass source that was used. It is therefore possible to anticipate which property values will be obtained for each biodiesel produced from a specific vegetable oil, relating them to the chemical nature of the starting vegetable oil. This study reports properties of oil formulations using blends of biodiesel obtained from castor oil and others biodiesel obtained from several raw materials (soybeans, cotton, and canola). Binary mixtures of these oils were prepared in concentration ranges between 20-80%vol. Each mixture was analyzed for viscosity and specific gravity. The proper formulation to meet the European specifications for biodiesel (DIN-14214) using those sources of biomass is presented and discussed.
