Biooil upgrading modelling

Abstract

The ever-increasing demand for energy on a global scale, in conjunction with the negative impact that fossil fuels have on the environment, has prompted the investigation of possible sustainable alternatives. The introduction of bio-oils, which are produced through pyrolysis and hydrothermal liquefaction from biomass, is an intriguing potential resolution. In order to improve the usefulness of bio-oils as renewable energy sources, this thesis investigates the upgrading and modelling of bio-oils to enhance their utility as renewable energy sources. Bio-oils possess complex compositions, including high oxygen content, which affects their stability and energy density. The study focuses on optimizing pyrolysis processes and upgrading techniques to improve bio-oil quality. Through detailed process simulations using Aspen Plus, key parameters such as temperature and pressure usage are analysed to maximize yield and quality. The findings indicate that specific operating conditions can significantly reduce undesirable by-products and enhance bio-oil properties, making it a viable alternative to conventional fossil fuels. This research contributes to the development of efficient bio-oil production and upgrading methods, promoting a sustainable energy future.
