Development of renewable based fuels for aviation

In this experimental work, natural calcium wastes have been used, separately or, in a blend of shellmix for producing biodiesel by heterogeneous catalysis. After several reactions, occurred between 30 minutes until 8 hours of reaction time, at 60 ºC, with a mass content of 5% (Wcat/Woil) and a molar ratio of methanol: oil = 12, after the purification process, biodiesel with fatty acid methyl ester (FAME) content measured, was higher than 99%, which indicates that was a biodiesel pure. Also, this work proved that, the inorganic solid wastes shell mixture used as heterogeneous catalyst, can be reused 3 times and still gives a FAME content higher than 99%. As a result, after 40 different transesterification reactions that were performed, using liquid and solid wastes for producing biodiesel under specific conditions which are stated above, is a successful, innovative and promising way. In addition, blends prepared with jet fuel A1 and biodiesel were recorded with no invalid results after certain tests. In this case, except for the 10% blend, the added biodiesel had no significant effect on the fluidity of the biojet fuel.
