“…Based on the latter conditions of operating pyrolysis parameter, biomass pyrolysis is categorized into the following subclasses: slow or conventional pyrolysis (Cong et al 2022), fast pyrolysis (Hu et al 2022), intermediate pyrolysis (Yang et al 2017), and flash pyrolysis (Nzihou et al 2019). Moreover, other technologies are recently utilized, such as microwave-assisted pyrolysis (Iturbides et al 2022), catalytic-based pyrolysis (Qiu et al 2022), catalytic hydropyrolysis (Nguyen et al 2016), and hydro-catalytic pyrolysis (Kawale and Kishore 2021) to optimize the products yields. Table 2 demonstrates modern works on lignocellulosic biomass in various pyrolysis methods with product distribution.…”

Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral and circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review the pyrolysis of algal and lignocellulosic biomass with focus on pyrolysis products and mechanisms, oil upgrading, combining pyrolysis and anaerobic digestion, economy, and life cycle assessment. Products include oil, gas, and biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification and transesterification, hydrotreatment, steam reforming, and the use of supercritical fluids. We examined the economic viability in terms of profitability, internal rate of return, return on investment, carbon removal service, product pricing, and net present value. We also reviewed 20 recent studies of life cycle assessment. We found that the pyrolysis method highly influenced product yield, ranging from 9.07 to 40.59% for oil, from 10.1 to 41.25% for biochar, and from 11.93 to 28.16% for syngas. Feedstock type, pyrolytic temperature, heating rate, and reaction retention time were the main factors controlling the distribution of pyrolysis products. Pyrolysis mechanisms include bond breaking, cracking, polymerization and re-polymerization, and fragmentation. Biochar from residual forestry could sequester 2.74 tons of carbon dioxide equivalent per ton biochar when applied to the soil and has thus the potential to remove 0.2–2.75 gigatons of atmospheric carbon dioxide annually. The generation of biochar and bio-oil from the pyrolysis process is estimated to be economically feasible.

“…Among them, pyrolysis has gotten a lot of attentiveness due to its low‐impact potency, proficient energy recuperation (syngas, bio‐oil, and bio‐char), and low‐pollution output. Bio‐oil has the potential to be burned (combusted) in industrial boilers or converted into transportation fuels, materials, and chemicals, meanwhile bio‐char has the potential to be utilized further in the treatment of water or soil enhancement and syngas to generate heat in industries 3–6 …”

“…Bio-oil has the potential to be burned (combusted) in industrial boilers or converted into transportation fuels, materials, and chemicals, meanwhile bio-char has the potential to be utilized further in the treatment of water or soil enhancement and syngas to generate heat in industries. [3][4][5][6] The goal of this research is to assess the thermal degrading nature of Helikha plant waste for energy conversion and determine whether the biomass may be used as a large-scale fuel. Helikha is a deciduous tree of the family Combretaceae and the genus Terminalia.…”

Non‐isothermal thermogravimetric tests of Terminalia chebula (Helikha) were conducted under inert N2 gas environment for temperatures (25–900°C) at heating rates of 10, 20, 35, and 55°C min−1. Kinetic triplet approximated employing five iso‐conversional methods namely, differential Friedman method (DFM), distributed activation method (DAEM), Ozawa–Flynn–Wall (OFW), Kissinger–Akahira–Sunose (KAS), and Starink (STK). Average values of activation energy (kJ mol−1) and frequency factor (min−1) calculated by the five models were 227.11, 2.98 × 1021 for DFM; 229.21, 4.63 × 1021 for KAS; 227.11, 3.81 × 1020 for OFW; 225.54, 1.15 × 1018 for STK; and 227.33, 3.02 × 1020 for DAEM respectively over the conversion range up to 0.8. In the kinetics study, correlation coefficient (R2) of greater than 0.97 is noticed in the conversion range of α = 0.1–0.8 for all models. From thermodynamic analysis, average values of ΔH (kJ mol−1), ΔG (kJ mol−1), and ΔS (kJ mol−1 K−1) for DAEM: 221.8, 179.69, and 0.065; for DFM: 236.40, 179.37, and 0.089; for KAS: 221.8, 179.69, and 0.065; for OFW: 220.22, 179.72, and 0.063; and for STK: 222.02, 179.68, and 0.066 were estimated to assess viability and reactivity of the process. Criado's master plots revealed that the data obtained from pyrolysis of selected biomass was followed a multistep reaction pathway.
