The biofuel mix in transport in the UK must be increased from currently exploited 3.33% to the EU target mix of 10% by 2020. Under the face of this huge challenge, the most viable way forward is to process infrastructure-compatible intermediate, such as bio-oil from fast pyrolysis of lignocellulosic biomass, into biofuels. New facilities may integrate multiple distributed pyrolysis units produc...

While ever-growing bio-ethanol production poses considerable challenges to the bioenergy supply chain, the risk of refinery operation disruptions further compromises the efficiency and reliability of the energy supply system. This paper applies discrete and continuous reliable facility location models to the design of reliable bio-ethanol supply chains so that the system can hedge against poten...

This research thesis validates the potential of tall oil as a renewable feedstock for the production of base-chemicals, especially olefins, as conceived in the thermo-chemical bio-refinery concept. The focus was on the use of hydrotreating and steam cracking technologies with different tall oil feedstocks. Particular advances were accomplished in terms of technology development for high yield o...

In particular, a straw-based Ablative Fast Pyrolysis (AFP) oil was upgraded via hydrotreatment (HDT) in order to be used as blending component with fossil-based intermediates. The raw pyrolysis is characterized by H/C = 0.14, O/C 0.58 and C 57.73 wt%, while the HDT has 0.016 85.85 wt%. Based on density, viscosity composition, association typical refinery, possible petroleum refinery entry point...

Background Biofuels from hydrothermal liquefaction (HTL) of abundantly available forest residues in British Columbia (BC) can potentially make great contributions to reduce the greenhouse gas (GHG) emissions from the transportation sector. A life-cycle assessment was conducted to quantify the GHG emissions of a hypothetic 100 million liters per year HTL biofuel system in the Coast Region of BC....

Pyrolysis bio-oil is unsuitable as transportation fuel due to its chemical composition and high oxygen (>30 wt%) water (>20 content rendering the upgrading essential prior any downstream use. The current work investigates of a flash pyrolysis via mild hydrotreatment (HDT), targeting potential intermediate refinery feed. Various operating parameters HDT were tested, including three temperatures ...
