ENERGY AND ECONOMIC ASSESSMENT OF JET FUEL, DIESEL AND GASOLINE PRODUCTION FROM HYDROTREATMENT OF FAST: FAST PYROLYSIS BIO-OIL FROM SUGARCANE STRAW

Pyrolysis is a physical-chemical process of thermal degradation of material in a nonoxidizing atmosphere, resulting in the formation of a solid residue rich in carbon (coal or char) and a volatile fraction composed of condensable organic gases and vapours. The proportions of these compounds depend on the pyrolysis method used, the process parameters and the characteristics of the treated material. Therefore, incorporating fast pyrolysis of lignocellulosic residues and the processing of bio-oil generated by this route into conventional sugarcane plants can lead to an increase in productivity and sustainability of the plant. The bio-oil is a liquid fuel that, unlike solid biomass, is easily transported, pumped and stored, however it still has certain disadvantages that do not allow its use as a fuel in the transport sector. Therefore, the objective of this study is to perform an energy and economic evaluation of the production of renewable jet fuel, diesel and gasoline from the hydrotreatment of bio-oil produced from the fast pyrolysis of sugarcane bagasse and straw. To produce the hydrogen necessary for the hydrotreatment process, production by electrolysis will be assumed. The modelling and simulation of pyrolysis process was carried out using the Aspen Plus software. A preliminary economic analysis will also be carried out to determine capital and operating costs as well as the minimum jet fuel selling price.
