The depletion of easily extractable oil reserves and the risks associated with the geographic concentration of these resources have stimulated the search for new raw materials. Thermochemical conversion is a feasible alternative to convert different wastes in bio-oils with high carbon content and that can be upgraded to obtain liquid fuels. The use of vegetable oils as a source of raw materials for the production of biofuels is presently a reality, namely by hydrogenation. Nevertheless the biofuels derived from hydrogenated vegetable oils are not yet economically competitive with the corresponding fossil fuels because of various factors such as scale of production, price of raw materials and price of hydrogen. Pyrolysis has been proposed as an alternative technology or as a preliminary step before hydrogenation because of the lower operational costs and less hazardous nature. The raw materials are efficiently decomposed under a nitrogen atmosphere and hydrogen is only used in a second step to improve the fuel quality namely by reducing their aromatic content. In this work, the vacuum pyrolysis of olive husk oil and a high acidity olive oil was studied at different reaction times to evaluate its feasibility in the production of bio-oils with a high carbon content.
