Biomass is the third largest primary energy resource in the world after coal and oil. Due to its huge potential, the renewable and the corresponding positive role for CO<SUB>2</SUB> reduction, the use of carbonized biomass for energy purpose is expected to increase. The carbonized biomass comes from agricultural waste and forest by-product. Carbonized plant and carbonized coconut cell biomass were mixed with water to study the possibilities of slurry preparation as a carbonized biomass water mixture (CBWM). Beside that, the upgraded coal by an upgraded brown coal (UBC) process was also studied to produce a UBC water mixture (UBCWM) with high coal concentration. The rheological characteristics of CBWM and UBCWM have been conducted by using a stress controlled rheometer. The results indicate that the maximum concentrations of the carbonized plant, carbonized coconut cell biomass, and UBC were 35.9, 51.2, and 61.5 wt%, when respectively using 0.3 wt% of naphthalene sulfonic acid (NSF), polymethacrylate (PMA), and NSF as dispersing additives, and 0.1 wt% of carboxyl methyl cellulose (CMC) as a stabilizing additive.
