Pyrolysis of butyl rubber tube waste was performed under an inert nitrogen gas environment for temperature ranging between 25 and 1,000 °C, by varying the heating rates (5, 10, 20, 35, and 55 °C min−1). Five different iso-conversional approaches, namely, Differential Friedman, Ozawa-Flynn-Wall, Kissinger-Akahira-Sunuse, Distributed activation, and Starink, were employed to investigate the kinetics and thermodynamic parameters. The mean activation energy (Eα), and pre-exponential factor (ko) varied between 222.67 and 244.73 kJ mol-1 and 6.82×1021 and 2.73×1024 s-1 respectively, for all iso-conversional approaches. From the kinetic investigation, a strong correlation co-efficient (R2>0.97) was ascertained in the conversion range of up to α=0.8 for all the iso-conversational approaches. By thermodynamic analysis, the mean values of change in enthalpy and change in Gibbs free energy were 217.06-239.13 kJ mol-1 and 185.12-218.11, kJ mol-1, respectively. From the master plot analysis, diffusion model (D3), and several reaction order models (F1, F2, F3, and F5) were predicted throughout the conversion (0.1 to 0.8) limit at 20 °C min-1 for the pyrolysis of BRT.

“…The series of steps which necessitates the thermal decomposition of biomass to its constituents are (i) evolution of moisture, (ii) hemicellulose decomposition, (iii) cellulose decomposition, and (iv) lignin decomposition. 13,21 The goal of kinetic analysis is to approximate kinetic parameters such as E α , k 0 , and reaction mechanism (or kinetic model), which are collectively known as the "kinetic triplet". The two most used methods for determining kinetic triplet are model-fitting and iso-conversional approaches.…”

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.

“…The primary distinction between co‐pyrolysis and co‐combustion lies in the reaction environment, with pyrolysis usually occurring under anaerobic conditions. Co‐pyrolysis of bamboo and plastics has garnered significant interest (Alam et al, 2021; Alam & Peela, 2022; Hou et al, 2022; Yao & Ma, 2018). Alam et al (2021) investigated the co‐pyrolysis capabilities of bamboo sawdust with linear low‐density polyethylene and found that the addition of bamboo sawdust accelerated plastic decomposition and enhanced the co‐combustion process.…”

Potential use of bamboo resources in energy value‐added conversion technology and energy systems

et al. 2023

View full text Add to dashboard Cite

Bamboo has been identified as a promising solution to the energy crisis and climate change as a source of biomass energy. Due to its rapid growth and high‐value products, bamboo is considered as a potential source of biomass energy. Bamboo contains a significant amount of cellulose and hemicellulose, which can be converted to sugar constituents, making it an ideal raw material for energy production. This article reviews the different processes of producing bioethanol, biogas, biochar, and bio‐oil from bamboo biomass using techniques such as pyrolysis, hydrothermal liquefaction, fermentation, and anaerobic digestion, and discusses the opportunities and challenges of these conversion technologies. It also reviews the main types and morphological characteristics of energy bamboo species and proposes an evaluation system for energy bamboo species, which optimizes the utilization efficiency of bamboo biomass energy and maximizes benefits by adopting appropriate methods for producing bioenergy based on the characteristics of different bamboo species.
