Effect of moisture content, forming temperature and structural components on Biocoke solidification from various biomass resources

The influence of additional hemicellulose on Japanese cedar based pre-carbonized solid biofuel properties

“…where " is maximum compressive strength at room temperature and is the additional hemicellulose ratio with ReducedChi-squares of 0.055 and Residual Sum squares of 0.109. This result support the conclusion ofTagami and Ida, 2018, that shows the approximate quadratic curve relationship between maximum compressive strength and hemicellulose content. From the estimate Gauss equation, the highest value would be at around 6 wt.…”

“…Raw materials with approximately 33 to 35 wt. % of total hemicellulose have the highest maximum compressive strength which is close to the estimation (30 %) inTagami and Ida, 2018 works.…”

“…After the sieving process, Japanese cedar powder size 53-150 µm was used as the base raw material of bio-coke. A standards ultimate analysis and a quantitative determination of lignocellulose component (Tagami and Ida, 2018) of JC powder is shown in Table 1. Cellulose is a dominant component among a lignocellulose in JC.…”

Surface Structural Transformation of Pre-carbonized Solid Biomass from Japanese Cedar via ATR-FTIR and PCA

“…The densification technology is involved with heating and pressuring of LC biomass in the manufacturing process. [6][7][8][9][10][11]13 Adjacent LC biomass particles bond via a solid bridge mechanism, which is a result of the softening behavior of its main components which act as natural binders. 13 Moisture content of raw materials and forming temperature affect densified products characteristics, especially mechanical characteristics.…”

“…Since the invention in 2005, the studies involved with bio-coke characteristics has been carried out, centered in the final products physical and mechanical properties. [5][6][7][8][9][10] However, transformations at the molecular scale have never been studied.…”
