“…It is known that deep deoxygenation to obtain low-oxygen bio-oil would lead to very low mass and energy yield. To see the overview of the current results in comparison with previous CFP studies 14,21,[26][27][28]31,40,[42][43][44]54,56,[65][66][67][68][69][70][71][72][73][74][75][76]85 applying either in situ or ex situ upgrading configuration, the mapping of the oxygen content versus energy yield is illustrated in Fig. 5.…”

“…Therefore, the use of such crude biomass oils remain a longer-term possibility. Table 1 shows the typical composition of various bio-based feedctocks that can be used for co-processing in refineries [16][17][18][19][20][21][22][23][24][25][26].…”

Several methods are currently used to track the bio-component of co-processed fuels including energy/mass balance, yield methods and radiocarbon techniques. The methods used to track or estimate the bio-component of fuels produced when bio and fossil feedstocks are processed together (co-processed) in oil refineries were analysed in detail, together with their advantages and disadvantages. Some methods, such as radiocarbon methods that allow the direct measurement of the bio-content in a fuel, have been criticised due to low accuracy at low blends. However, these reservations have tended to misinterpret the options available for carbon dating and to discount recent improvements in these tests. As much higher co-pressing mixtures are anticipated if published national decarbonisation targets are to be achieved, any challenges at very low co-processing ratios affecting the accuracy of the radiocarbon methods should not be an issue. Energy/mass balance and yield methods might be supplemented with carbon-tracking to determine the real the biogenic content.

“…Slow pyrolysis produces solid products such as biochar or charcoal, while fast pyrolysis results in the production of liquid products (bio-oil). It is reported that forest biomass is an ideal feedstock for pyrolysis (Chireshe et al, 2020), and different researchers have successfully conducted pyrolysis of forest biomass to produce bio-oil (Oasmaa et al, 2010;Puy et al, 2011;Stefanidis et al, 2015;Luo et al, 2017). It should be noted that the bio-oil produced by the pyrolysis process typically has a high oxygen and water content, and thus, it should be upgraded (van Schalkwyk et al, 2020).…”

Biomass plays a crucial role in mitigating the concerns associated with increasing fossil fuel combustion. Among various types of biomass, forest biomass has attracted considerable attention given its abundance and variations. In this work, an overview is presented on different pathways available to convert forest biomass into bioenergy. Direct use of forest biomass could reduce carbon dioxide emissions associated with conventional energy production systems. However, there are certain drawbacks to the direct use of forest biomass, such as low energy conversion rate and soot emissions and residues. Also, lack of continuous access to biomass is a severe concern in the long-term sustainability of direct electricity generation by forest biomass. To solve this problem, co-combustion with coal, as well as pelletizing of biomass, are recommended. The co-combustion of forest biomass and coal could reduce carbon monoxide, nitrogen oxides, and sulfide emissions of the process. Forest biomass can also be converted into various liquid and gaseous biofuels through biochemical and thermochemical processes, which are reviewed and discussed herein. Despite the favorable features of forest biomass conversion processes to bioenergy, their long-term sustainability should be more extensively scrutinized by future studies using advanced sustainability assessment tools such as life cycle assessment, exergy, etc.
