“…It is probable that many of the biocrudes that might be upgraded at a refinery will contain larger molecules composed of phenols, catechols, guaiacols, and syringols . Consequently, some form of cracking will be required to create shorter molecules that comply with the specifications for specific fuels.…”

“…Most of the past catalytic pyrolysis oil work used acidic zeolites, particularly HZSM‐5 . However, this catalyst has been shown to deactivate quickly and often needs frequent replacement due to the contaminants like ash in the biomass . This adds significant costs to the process and is thought to be one of the major technical difficulties encountered by KiOR who failed to commercialize this technology…”

Drop‐in biofuels have been defined as functionally equivalent to petroleum‐based transportation fuels and are fully compatible with the existing petroleum infrastructure. They will be essential in sectors such as aviation if we are to achieve emission reduction and climate mitigation goals. Currently, ‘conventional’ drop‐in biofuels, which are primarily based on upgrading of lipids / oleochemicals, are the only significant source of commercial volumes of drop‐in biofuels. However, the necessary increased, future volumes will likely come from ‘advanced’ drop‐in biofuels based on biomass feedstocks such as forest and agriculture residues. Biocrudes / bio‐oils produced from lignocellulosic feedstocks using thermochemical technologies such as gasification, pyrolysis, and hydrothermal liquefaction need to be further upgraded to drop‐in biofuels. However, advanced drop‐in biofuels have been slow to reach commercial maturity due to significant technical challenges, high capital costs, and the challenge of generally lower oil prices. It is likely that the co‐processing of drop‐in biofuels with conventional petroleum refining could considerably reduce capital costs. Initially, co‐processing is likely to be established through the upgrading of conventional / oleochemical feedstocks (lipids). Lipids are readily available in large volumes (global production in 2017 was ~185 million metric tonnes) and can be more easily integrated into oil‐refinery processes. In contrast, lignocellulose‐derived biocrudes / bio‐oils are not yet available in significant volumes and are more complex to co‐process in a refinery. The likely strategies for co‐processing of oleochemicals (lipids) and bio‐oil and biocrude feedstocks based on different insertion points within the refinery infrastructure are discussed. © 2019 The Authors.

“…With regard to GS pyrolysis, the liquid fraction resulting from the non-catalytic co-pyrolysis process was composed of two phases (aqueous and organic), which were easily separated by centrifugation. While the organic phase is the most interesting fraction for use in fuel and energy applications [48], the possibilities for valorising the aqueous phase are still limited, given that the production of chemical products such as H 2 , ethanol or even light acids is the option attracting more interest. Accordingly, the main target of this study was focused on improving the yield and fuel properties of the organic phase.…”

Ca-based Catalysts for the Production of High-Quality Bio-Oils from the Catalytic Co-Pyrolysis of Grape Seeds and Waste Tyres

et al. 2019

The catalytic co-pyrolysis of grape seeds and waste tyres for the production of high-quality bio-oils was studied in a pilot-scale Auger reactor using different low-cost Ca-based catalysts. All the products of the process (solid, liquid, and gas) were comprehensively analysed. The results demonstrate that this upgrading strategy is suitable for the production of better-quality bio-oils with major potential for use as drop-in fuels. Although very good results were obtained regardless of the nature of the Ca-based catalyst, the best results were achieved using a high-purity CaO obtained from the calcination of natural limestone at 900 °C. Specifically, by adding 20 wt% waste tyres and using a feedstock to CaO mass ratio of 2:1, a practically deoxygenated bio-oil (0.5 wt% of oxygen content) was obtained with a significant heating value of 41.7 MJ/kg, confirming its potential for use in energy applications. The total basicity of the catalyst and the presence of a pure CaO crystalline phase with marginal impurities seem to be key parameters facilitating the prevalence of aromatisation and hydrodeoxygenation routes over the de-acidification and deoxygenation of the vapours through ketonisation and esterification reactions, leading to a highly aromatic biofuel. In addition, owing to the CO2-capture effect inherent to these catalysts, a more environmentally friendly gas product was produced, comprising H2 and CH4 as the main components.

“…The reason behind this impact was that the production of bio-oil was the most profitable bio-product conversion option in this collaboration, accounting for over 70% of the supply chain's total revenue. However, it is worth noting that pyrolysis technology is still undergoing the process of development (Dabros et al, 2018;Hu & Gholizadeh, 2019). In Brown, Thilakaratne, Brown, & Hu, (2013), it was mentioned that no commercial-scale fast pyrolysis facilities were being constructed by the year of 2010.…”
