“…Thus, it is easier for the biomass to decompose when subjected to heating (Quan & Gao, 2016). Similar findings have also been reported by Vuthaluru (2004) on pyrolysis of wood waste and wheat straw, He et al (2018) on co-pyrolysis of bituminous coal and fermented cornstalk, and (Panwar et al, 2020) on co-pyrolysis of raw/torrefied biomass and coal blends, and (Quan et al, 2014) on white pine and bituminous coal using thermogravimetric analysis. The synergistic interaction between the SC and EFB can be observed from the additive or non-additive behavior based on the sum of weighted average of the mass loss profile, as indicated in Eq.…”

“…As can be seen, both samples followed the same thermal evolution profile as their parent fuel. Maximum rate of devolatilization (also known as peak height) gradually increases with an increasing amount of biomass in the blends due to high volatile quantities released (Idris et al, 2010;Vamvuka et al, 2003;Panwar et al, 2020)). This also shows improved reactivity of the sample where biomass increment will increase the maximum rate of mass loss (Jayaraman et al, 2017).…”

Agricultural residues have been traditionally used as energy resources for many years. In light of current environmental and fossil fuel supplies for energy applications, agricultural residues are regarded as sustainable supplies for energy production. However, the suitability to be renewable fuel and as a co-fuel in coal combustion facilities has to be investigated. A thermal analysis was conducted to investigate the effect of the blending and heating rate of the thermal behavior of Malaysian bituminous coal (Silantek), oil palm biomass (empty fruit bunch), and their blends using thermogravimetric analysis. The investigation was done in an inert atmosphere at the heating rate of 10, 20, and 40°C/min. Characteristics including proximate, ultimate, and calorific analyses were also examined. Six different mass ratios were selected from both samples to study the effect of blending of the two materials. The results showed that thermal degradation of empty fruit bunch (EFB) occurred in three stages while Silantek coal (SC) only involved two regions due to their different fuel properties. The blending of both SC/EFB did not follow their individual samples, which showed non-additive behavior suggesting that there is an interaction between coal and biomass. The outcome of this research provides insight on the behavior of Malaysian bituminous coal and oil palm biomass, which enhances knowledge for the future of energy generation.

“…The DTG peak of RM, RM-200, and RM-250 was observed at 320 °C (-0.49 %/°C), 319°C (-0.50 %/°C), and 332°C (-0.42 %/°C), respectively. However, the DTG peak associated with the decomposition of hemicellulose did not appear in the RM-300 sample torrefied at 300 °C [60].…”

Torrefaction enhances the properties of biomass fuels which adds to their suitability as energy sources. Due to abundance availbiluty of mustard straw in the northern region of India and throughout the globe, the raw or torrefied mustard straw were investigated in the present study. The torrefaction experiments were conducted on mustard straw using heating temperatures of 200°C, 250°C, and 300°C for 60 minutes. The biomass characterization were carried out using proximate analysis, ultimate analysis, and High Heating Values (HHV). Afterward, NOx, SO2, CO2, CO, and dust emissions are evaluated from the combustion of raw/torrefied mustard straw. After the experimentation, the results have been compared with the literature. It was observed that during torrefaction, the carbon content of biomass increases with the increase in temperature, while the hydrogen and oxygen contents decreased. Further, the liginin content increases while hemicellulose content decomposes with the increase in temperature. It was seen that energy yield for a torrefied mustard straw at 200°C, 250°C, and 300°C was 76.24%, 88.98%, and 94.75%, respectively. The process of torrefaction, increases the bulk density, decreased the mass yields and improves the ignitability indices of the mustard straw. The outcomes of this research are expected to provide practical insight into how raw mustard straw can be upgraded into densified solid biofuels suitable for industrial and thermal power plant applications.

The physicochemical characteristics and kinetics of sugarcane bagasse (SCB) and black gram straw (BGS) have been studied using a thermogravimetric analyzer under nitrogen atmosphere at 20°C/min heating rates. The analysis showed that SCB has higher volatile matter (81.32 wt.%), lower ash (3.50 wt%), and moisture content (5.36 wt%) while signi cantly higher HHV (18.10 MJ/ kg). The TG and DTG curves displayed four signi cant zones mainly attributed to moisture removal, decomposition of hemicellulose and cellulose, and lignin, respectively. The Coats-Redfern model tting method was used to determine the kinetic and thermodynamic parameters of the active pyrolysis zone. The activation energies of SCB and BGS were 88.74 and 96.74 kJ/mol, respectively. The following thermodynamic parameters were found: change in enthalpy is 83.65 and 92.14 kJ/mol, Gibbs free energy is 126.64 and 144.69 kJ/mol, and change in entropy is -73.29 and − 94.92 J/mol.K, for SCB and BGS, respectively. These physicochemical properties and kinetic parameters con rm that SCB and BGS are promising feedstocks for pyrolysis.
