“…A typical mass and energy balance for the torrefaction of woody biomass is that 70% of the mass is retained as a solid product, containing 90% of the initial energy content. The other 30% of the mass is converted into torrefaction volatiles, which contains only 10% of the energy of the biomass [114]. The removal of moisture reduces the microbial activity, e.g., the likelihood of rotting is diminished due to the more hydrophobic character of torrified biomass, so the storage and transportation become easier.…”

“…Urgency of the problem of agro-industrial complex wastes recycling with the use of composite fuels is confirmed by numerous publications (for example, [8][9][10][11][12][13][14]), which give results of fuels properties study based on biomass and coals during combustion in power plants. But results of [8][9][10][11][12][13][14] are not the basis for consistencies analysis of composite fuels thermal decomposition processes with a change in the ratio of biomass and coal concentration.…”

Analysis of composite fuels creation possibility with energy characteristics close to the initial coal and significantly better environmental parameters (close to biofuels) is of great interest.…”

Abstract. Experimental studies were conducted to determine the energy and technical characteristics of composite fuels from T grade coal (Alardinsky deposit) and oats (Shegarsky district, Tomsk region). An effective concentration of composite fuel of 50% / 50% is established, at which the heat of combustion is reduced by less than 2%, the ash content is up to 44%, and the fly ash output is up to 48%.

“…Although Eseltine et al [9], Medic et al [10], Uemura et al [11], Van der Stelt et al [12], Deng et al [13], and Bergman et al [14] proposed that the energy intensification and mass loss of biomass are proportional to the heating temperature of 200-300 °C but they are all tinged with uncertainty as the temperature range is too wide and does not specify a precise effect of different torrefaction temperature towards particular biomass. Hence, the objective of this study is to investigate effect of torrefaction on the physical characteristics of the rice waste at different temperature.…”

Abstract-Biomass plays a crucial role as the source of renewable carbon which can be utilised in the production of biofuels. However, the raw biomass itself has some undesirable properties such as high moisture content, low energy density and deterioration after a short duration of storing period. Hence, a thermochemical process, known as torrefaction is normally used to preliminary treat the biomass to enhance its physical properties. This study focus on the characterization of the physical properties of the torrefied rice biomass which are rice husk and rice straw under three different temperatures of 220 °C , 250 °C and 280 °C with residence time of 30 min.The heating rate was set as 15 °C /min after the temperature profile study on the customized reactor was investigated. From the experimental results, it is noticeable that torrefaction enhances the calorific value of the biomass by 3-17% for rice husk and 4-20% for rice straw. The torrefied rice-based biomass also helps to remove the moisture content of raw rice husk and rice straw by 6.5% and 8.3% respectively. The mass yield of the torrefied rice-based biomass is between the range of 78-91% for rice husk and 82-90% for rice straw. Meanwhile, the energy yield for rice husk is in the range of 92-94% and 93-98% for rice straw after torrefaction. This study concludes that 250 °C is the optimum torrefaction temperature for the conversion of rice waste into valuable biofuel.
