The Influence of the Use of Pyrolysis Oil as a Binder on the Physicochemical Properties of Pellets

Abstract

The article presents the results of research on the effect of pyrolysis oil used as a binder in the pelletization process. The materials used to produce pyrolysis bio-oil were municipal organic waste and residues from greenhouse tomato production. The research assessed the mechanical strength, physicochemical properties, and modifications of the energy and emission parameters of the produced pellets. As a result, formed fuels were obtained, whose physicochemical properties, among others, were improved in terms of combustion heat (the value increased by up to 15.7%). After selected binders were used, the mechanical strength of the fuels also increased, which in the best variant increased by 2.87%. In all research cycles, valuable data was obtained that can be used, for example, in companies producing formed fuels, as well as in the agri-food industry, where a large amount of waste is generated, the properties of which have not previously allowed their use for energy purposes.
