“…The carbon content of SCG-T280 reached 68%, which was similar to that of bituminous coal and corresponded to the highest HHV. Additionally, the nitrogen content of AFB was relatively low, indirectly indicating that charcoal from AFB may reduce NOx emissions and minimize coke and smoke generation in future thermal conversions [35]. The van Krevelen diagram is an effective method for elucidating the characteristics of solid fuels, as illustrated by the H/C and O/C ratios of different fuels in Figure 3.…”

The pretreatment for torrefaction impacts the performance of biomass fuels and operational costs. Given their diversity, it is crucial to determine the optimal torrefaction conditions for different types of biomass. In this study, three typical solid biofuels, corn stover (CS), agaric fungus bran (AFB), and spent coffee grounds (SCGs), were prepared using fluidized bed torrefaction. The thermal stability of different fuels was extensively discussed and a novel comprehensive fuel index, “displacement level”, was analyzed. The functional groups, pore structures, and microstructural differences between the three raw materials and the optimally torrefied biochar were thoroughly characterized. Finally, the biomass fuel consumption for household heating and water supply was calculated. The results showed that the optimal torrefaction temperatures for CS, AFB, and SCGs were 240, 280, and 280 °C, respectively, with comprehensive quality rankings of the optimal torrefied biochar of AFB (260) > SCG (252) > CS (248). Additionally, the economic costs of the optimally torrefied biochar were reduced by 7.03–19.32%. The results indicated that the displacement level is an index universally applicable to the preparation of solid fuels through biomass torrefaction. AFB is the most suitable solid fuel to be upgraded through torrefaction and has the potential to replace coal.

“…Traditionally, Pongamia has been employed in India and its neighboring countries as a source of traditional medicines, green manure, wood, animal feed, fuel, biopesticide, and fish poison [3]. As a fuel, Pongamia is a potential resource for sustainable aviation fuel production due to the high oil content of its seeds [4]. In recent years, Pongamia oil has been recognized as a viable source of oil for the burgeoning biofuel industry.…”

Pongamia pinnata (L.) Pierre is a multipurpose tree species that produces non-edible seeds. Pongamia oil has been recognized as a viable source of oil for the burgeoning biofuel industry. The economic feasibility of Pongamia depends on the oil content of the seed. Meanwhile, information on variation among families (parent tree) of seedlings grown is also necessary to increase plant productivity besides the oil content. This study aims to determine the variation among families of Pongamia oil content and seedling growth (generative and vegetative propagation). The seeds were analysed using 48 families for oil content analysis by solvent extraction, 50 families for seedling growth analysis (generative), and 19 families for vegetative. The result showed a significant variation in crude oil content among the families. Oil production varied from 26.61 to 44.68%. Variations among families were also found in seedling growth performance for both generative and vegetative propagation, with an average survival rate up to 75%. The information is essential for the tree improvement program to produce genetically improved seeds of Pongamia for biofuel and land restoration in Indonesia.

A report on the Pithecellobium dulce tree is provided in this review. The main characteristics of the tree, its chemical composition, traditional applications and future application in the bioenergy area are addressed. Pithecellobium dulce is a leguminous tree characterized by being fast growing, nitrogen fixing and largely available. In addition, it is distinguished by growing in different types of soils from acid to alkaline and with little water. This review could serve as a scientific basis to promote and carry out new research work focused on individual and comprehensive use for various bioenergetic processes, from the different parts that make up the P. dulce tree such as its leaves, pods, branches, flowers, fruit and seeds. Among the bioenergetic processes that could be developed are the production of bioethanol, biodiesel, biogas, heterogeneous catalysts, biochar, activated carbon and nanoparticles, among other applications.
