“…Pyrolysis is one of the most effective process to convert biomass into a wide range of products including bio‐oil, biochar, and bio‐syngas . Hence, employing pyrolysis technique to treat the textile solid waste has also been paid more attentions by many researchers . Among them, direct conversion of textile solid waste into activated carbon materials has been regarded as a useful way for energy storage and environmental protection .…”

Conversion of biomass waste into nitrogen-doped porous carbon has been considered as a promising approach to achieve energy storage materials. Nitrogen-doped activated carbon materials have been successfully prepared by molten salt pyrolysis (MSP) using melamine modified-denim fabric waste as precursor. The molten salt medium provides liquid condition to carbonize and activate the denim fabric waste. Melamine produces a large amount of nitrogen element for doping the carbon materials. The obtained nitrogen-doped denim fabric-based carbon materials (NDFC-MSP) are composed of small fibrous fragment and thin sheet, and exhibit a high specific surface area (1975.2 m 2 ⋅g À 1 ) and high pore volume (1.087 cm 3 ⋅g À 1 ). Moreover, NDFC-MSP sample with a high nitrogen content of 6.93 wt.% possesses a maximum specific capacitance of 345.8 F⋅g À 1 at 0.25 A⋅g À 1 in 6 M KOH electrolyte. It also displays a high specific capacitance of 230 F⋅g À 1 at 10 A⋅g À 1 . The cycle stability shows 95.5% retention after 5000 charge-discharge cycles at 1 A⋅g À 1 . In addition, the fabricated symmetric NDFC-MSP supercapacitor with a wide voltage range of 1.8 V generates a maximum energy density of 17.0 Wh⋅kg À 1 at power density of 225 W kg À 1 in 1 M Na 2 SO 4 aqueous electrolyte.

“…13 Both decomposition behaviour and kinetics should be investigated to determine the most suitable design and operation of pyrolytic process. 14 Thermogravimetric analysis (TGA) is the most common and simplest method of evaluating the kinetics of pyrolysis. [15][16][17] The TGA determines the weight loss during sample decomposition as a function of time or temperature under inert atmosphere at a constant heating rate.…”

The characteristics and kinetics of durian shell (DS) pyrolysis were investigated using non-isothermal thermogravimetric analysis (TGA). DS is a celluloserich biomass with high volatile matters content, which is suitable for bio-oil production. Thermal decomposition experiments were performed under nitrogen flow at various heating rates (i.e., 5°C min -1 , 10°C min -1 and 20°C min -1 ). The model-fitting method represented by Coats-Redfern was applied on the experimental TGA data of DS pyrolysis. The decomposition of DS was divided into three stages: first stage (59°C-200°C) involved removal of moisture and light volatiles; second stage (200°C-400°C) showed decomposition of cellulose and hemicellulose; and third stage (above 400°C) presented lignin decomposition. There was 56% weight loss observed in second stage, revealing that decomposition of cellulose and hemicellulose contributed the most on volatile production. The model shows that the activation energy was between 42.08 kJ mol -1 and 84.40 kJ mol -1 for the second stage of the pyrolytic process from 200°C to 400°C using different decomposition mechanisms. The Coats-Redfern method is applied successfully for the correlation of experimental TGA data with an average correlation coefficient (R 2 ) of 0.991 while one-way diffusion model D1 gave the highest correlation coefficient of 0.998. DS biomass is a suitable raw material for energy or chemicals production.
