Πυρόλυση φυτικών ελαίων και ζωικών λιπών κάτω από διαφορετικές συνθήκες για την παραγωγή ανανεώσιμων καυσίμων

Abstract

The need for energy is continuously increasing nowadays, if we take into account the rapid population growth and industrial development. Currently, this demand is satisfied partially by conventional energy resources and fuels such as coal, by 41,3%, natural gas, by 21,9%, nuclear, by 11,7%, oil, by 4,8% etc., which are also regarded responsible for a great deal of environmental problems, such as global warming or greenhouse emissions. As a result there has been the need of people to find ways to protect their natural environment and subsequently come up with more environmentally friendly solutions regarding energy development and exploitation. This is exactly where the issue of bioenergy emerges. Bioenergy is a renewable energy made available from materials derived from biological sources. One of the renewable resources that has gradually started to gain more and more interest is biomass. In this project, experimental study and research has been carried out in order to create fuels out of natural products such as vegetable oils and animal fats. In the latest years, pyrolysis of biomass has become quite popular as a source for energy production and fuels. Through the process of pyrolysis, there is production of bio liquids and biofuels, which can be considered alternative and efficient materials in terms of fuels. With further treatment, their products can be adapted and added to refined petroleum products. More specifically, the pyrolysis of oils and fats allows the thermochemical conversion of triglycerides to substances with similar properties to those of gasoline. As a result, the aim of this paper was to study and monitor the effect of some control parameters in the pyrolysis processes of vegetable and aviary oils, taken into account their acidity, profiles, age so as to compare the conversion yields of the products produced with those of the biofuels.
