“…It can be even more confirmed that the nitrogen and sulfur percentages of EL are quite higher than that of EB and ESD. However, the N content of EL (3.49%) is higher than some lignocellulosic biomass: alfalfa (2.39%) [25], wheat straw (0.38%) [25], giant reedgrass (2.24%) [26], cotton cocoon shell (1.3%) [27], cotton stalk (1.12%) [28], sugarcane bagasse (0.15%) [28]. And the sulfur content of EL (0.45%) is also higher than some other lignocellulosic biomass, such as palm kernel shell (0.38%) [29], sugarcane bagasse (0.24%) [30], cotton stalk (0.17%) [30].…”

“…However, pretreatment of biomass, either thermally, or mechanically, is needed to upgrade virgin biomass into more efficient solid fuel for gasification. Recently, torrefaction technology has attracted more attention to upgrade biomass and make it useable in gasification or combustion . Torrefaction is a mild thermochemical process that has been widely studied aiming to mitigate biomass drawbacks, performed in oxygen‐free atmosphere in the temperatures range of 200–300°C for several minutes or few hours .…”

In this study, a mixture of breeding lines of Erianthus arundinaceus energy grass was pretreated prior to gasification. Although biomass torrefaction and subsequent pelletizing of torrefied biomass (TOP process) have been studied in details, the torrefaction of pellets (TAP process) still in its infancy. Therefore, samples prepared by TAP, torrefaction‐only and pelletizing‐only were compared in terms of fuel characteristics and gasification kinetics. Results showed that the mass yield decreased with increasing torrefaction temperature, whereas the higher heating value (HHV) continued to increase with temperature, which can be seen in the evolution of O/C and H/C atomic ratios. Tradeoff between mass yield and HHV points to 250°C as the optimum torrefaction temperature, as mass yield above 76% could be achieved. TAP process was superior not only in terms of producing fuel with higher energy density, but also the gasification reactivity was higher than that of torrefied‐only or densified‐only samples, suggesting TAP is promising to be employed within the gasification process. Yet, conducting TAP under higher torrefaction temperatures may weaken the reactivity due to the more release of potassium during pyrolysis. Lastly, gasification kinetics data revealed that the pretreated samples exhibited slightly higher activation energy.

“…Pyrolysis is a promising thermic process for obtaining liquid products. In this process, the quantity and quality of the biochars, bio-oil, and gaseous products depend on the pyrolysis conditions, e.g., the pyrolysis temperature, gas flow rate, pressure, and heating rate, and the particle size of the material used in the process [15,[21][22][23][24]. Algae biomass contains a large amount of lipids; therefore, pyrolysis can be used to extract bio-oil.…”
