Lignin has been shown to act as natural binders in pellets derived from lignocellulosic biomass even after HT is below 250 C. 11,26 This feature consequently avoided the addition of external binders (or additives) in pelletizing all of the hyrochar pellet samples.…”

Summary Residues from banana and coconut timber production offer potential advantages if used as solid fuel. This study investigated the gasification behavior of co‐pelletized, hydrothermally treated banana leaves (HBL) and coconut sawdust (HCS) at varied blend ratios. Pellet quality tests revealed that the individual and co‐pelletized HBL:HCS samples have excellent mechanical integrity. Their high compressive strengths, high mass densities, and low spring back effects likewise indicate their ability to form strong interparticle adhesion without the aid of external binders or modification of particle sizes. Although HCS showed slow char gasification conversion, co‐pelletization with HBL proved to enhance its reactivity. This improvement was due to HBL's significantly higher alkali index compared with HCS. Since increasing the HBL ratio increased the alkali index of the co‐pelletized samples, the pellet with the highest HBL ratio (HBL:HCS 3:1) showed the greatest reactivity enhancement. Gasification of the blended HBL and HCS pellets also produced a synergistic effect, which was most evident when the HBL ratio was lowest (HBL:HCS 1:3). The significant difference in the particle size of HBL and HCS, aggravated by increasing the HBL ratio, formed large interspaces that weakened the degree of synergy. Overall, findings revealed that mixed HBL and HCS can produce high‐quality pellets with enhanced gasification reactivity and synergistic effect. Novelty Statement Gasification of binderless co‐pelletized hydrochars was proposed. Co‐pelletization showed high compressive strengths, high mass densities, and low spring back effects. Co‐pelletization of hydrochars enhanced gasification reactivity and synergistic effect.

Effect of Compaction Pressure and Moisture Content on Post-Agglomeration Elastic Springback of Pellets

Renewable energy sources (RES) represent an increasing share of global energy production. Biomass has the highest potential of all RES. Biomass is used to produce solid biofuels, liquid biofuels, and gaseous biofuels. One of the main directions of research on solid biofuels is to optimize the agglomeration process. The main factors determining the characteristics of the final product in the production of pellets are process and material parameters. Process parameters include compaction pressure, temperature, and geometry of the matrix channel. The parameters of the material are the type of biomass, moisture content, degree of fragmentation, and method of preparation of the material (e.g., drying). The process of pressure compaction is always associated with the negative phenomenon of elastic springback. The aim of this work was to check the influence of compaction pressure and material moisture content on the springback value. The research was conducted on three materials (giant miscanthus, cup plant and Virginia mallow), using four different pressures (131, 196, 262, and 327 MPa) and three different moisture levels (8, 11, and 14%). For all material springback values, the range was 9–16%. Statistical analysis showed that for all plants tested, the effects of compaction pressure and moisture content significantly affected the elastic springback value. Areas of high value springback in the pattern of process parameters were determined.
