“…However, when compared to conventional energy sources such as coal, biomass has a higher oxygen content, higher moisture content, lower ash melting temperature, and lower calorific value . Combining coal and biomass is one solution to maintain energy content through methods such as cofiring, , cogasification, − and copyrolysis. − In addition, the combination of biomass and fossil fuels, such as coal, provides many advantages. The addition of coal to biomass can increase the energy density of the feedstock and reduce fluctuations in the supply of biomass.…”

The copyrolysis of the green microalgae Botryococcus braunii and Victorian brown coal was studied by thermogravimetric analysis using the Kissinger−Akahira−Sunose (KAS), Flynn−Wall−Ozawa (FWO), and Friedman methods. This research aims to study the synergistic effect of mixing B. braunii and Victorian brown coal in pyrolysis reactions on the kinetic parameter using thermogravimetric analysis. Copyrolysis was carried out at four heating rates, 10, 15, 20, and 25 °C/min. The copyrolysis reaction of B. braunii and Victorian brown coal occurred from 155.79 to 545.27 °C; this temperature range was lower than that for the pyrolysis of only B. braunii under the same conditions. However, mixing the two samples increased the thermal decomposition temperature for each conversion value (α), as well as the average activation energy, due to the presence of compounds that require high temperatures to undergo pyrolysis in the Victorian brown coal. The average activation energies of the copyrolysis reaction of B. braunii and Victorian brown coal determined using the KAS, FWO, and Friedman methods were 195.20

“…TGA (Thermo-gravimetric analysis) curve on feed stock material exhibited the decomposition rate versus temperature. 30 The obtained resultant graphs can be separated into 4 regions. That is, first (T < 200 C), second (200 C < T < 300 C), third (300 C < T < 500 C) and fourth decomposition (T > 500 C) regions.…”

The deficiency of fossil fuel resources, amplifying fuel price and its related environmental anxieties grasped great attention for finding an alternative fuel. Such alternative options can be fuels obtained from agricultural residues, plants, and wastes. The present research emphases on complex proportional assessment (COPRAS) and gray relational analysis (GRA) modeling of a diesel engine fuelled by Annona squamosa (AS) and Aegle marmelos (AM) co‐pyrolysis oil/diesel binary opus as an engine fuel to optimize the engine characteristics. Co‐pyrolysis oil is obtained from AS+AM feedstock at pyrolysis temperature of 500°C. To obtain engine data for training and testing the proposed COPRAS and GRA models were adopted for the engine control factors such as engine load (W) and compression ratio (CR) in a test engine rig through experimentation and hybrid optimization technics. From the engine output responses reveals that F2080 opus delivers an augmented brake thermal efficiency (22.01%) than diesel (21.56%) at peak load. Subsequently, F2080 fuel emits substantial lessening of CO (11.88%) and HC (5.64%) emissions as compared to diesel (F0). Based on the results, it is conclude that F2080 blend at CR of 17.5 and 100% load was delivered the greater engine distinctiveness through optimization outcomes and experimental evaluation compared to F0.

“…Prior investigations have looked into the pyrolysis of a variety of different types of biomass, such as purun tikus [5], corn corb [6], white oak [7], waste sawdust [8], waste engine oil [9], animal waste [10], rice straw and bamboo [11], and milkweed [12]. These pyrolysis processes have been conducted in xed bed reactors [13][14][15], stirred-bed reactors [16,17], and uidized bed reactors [18][19][20] under different experimental conditions, including variations in reaction temperature, biomass type, particle size, reaction time, heating rate, feeding rate of feedstock and ow rate of the carrier gas.…”

In this research, a series of experiments on pyrolysis of brown algae "Padina sp." were conducted in a batch reactor under different temperatures (400, 500, and 600 oC) and reaction times (30, 60, and 90 min) in order to investigate the product behavior and the kinetic of solid degradation of Padina sp. during the pyrolysis process. The results showed that the bio-oil from Padina sp. can be split into its constituent parts, with chemicals such as carboxylic acids, hydrocarbons, n-aromatic compounds, amines/amides, and phenolic compounds identified. The ultimate analysis demonstrated that the atomic ratios of the biochar, both H/C and O/C, were lower than those of the raw material. The calorific values vary from 20.96 to 22.25 MJ kg− 1. A scanning electron microscopy (SEM) study of surface morphology also revealed that the biochar formed had a greater surface area than the algal feedstock. Additionally, the reaction kinetics of solid degradation at varied temperatures was deduced. The pre-exponential factor and activation energy for the degradation of solid feedstock were successfully determined for the first time using the Arrhenius equation as 8.44x1010s− 1 and 144.4 kJ mol⁻1, respectively.
