“…It is worth mentioning that wood products have interesting properties for energetic use, like high calorific values (approximately 17 MJ/kg [ 9 ]). There have been several applications proposed for wooden waste products’ usage, such as activated carbon production [ 10 ], briquette production for energetic purposes [ 11 , 12 ], adding wooden furniture waste in the process of fired clay brick production for the improvement of thermal insulation [ 13 ], and wood-polymer composite (WPC) production [ 14 ].…”

The aim of this study was to assess the possibility of using furniture waste for smokeless fuel production using the pyrolysis process. Four types of wood-based wastes were used in the pyrolysis process: pine sawdust (PS), chipboard (CB), medium-density fiberboard (MDF), and oriented strand board (OSB). Additionally, the slow and fast types of pyrolysis were compared, where the heating rates were 15 °C/min and 100 °C/min, respectively. Chemical analyses of the raw materials and the pyrolysis product yields are presented. A significant calorific value rise was observed for the solid pyrolysis products (from approximately 17.5 MJ/kg for raw materials up to approximately 29 MJ/kg for slow pyrolysis products and 31 MJ/kg for fast pyrolysis products). A higher carbon content of char was observed in raw materials (from approximately 48% for raw materials up to approximately 75% for slow pyrolysis products and approximately 82% for fast pyrolysis products) than after the pyrolysis process. This work presents the possibility of utilizing waste furniture material that is mostly composed of wood, but is not commonly used as a substrate for conversion into low-emission fuel. The results prove that the proposed solution produced char characterized by the appropriate properties to be classified as smokeless coal.

“…The raw materials and the pyrolysis product yields were analyzed and compared. Activation of char has another possible use as an adsorbent [ 10 ], for applications in building materials [ 38 ], or as catalyst support for biomass conversion [ 39 , 40 , 41 ], and such studies have been planned for future.…”

“…A 1:1 molar ratio was also checked, but the higher amount of activated agent caused too intensive oxidation of the chestnut-derived biochar and resulted in a lower SSA (21.2 compared to 105.7 m 2 g −1 for 1:1 and 0.5:1 CO 2 :C biochar ratio, respectively). However, it is worth noticing that the amount of activated agent needed for the effective activation depends largely on the type of biomass as well as the structure and chemical composition of biochar [ 46 ].…”

In this work, we present the preparation and characterization of biomass-derived activated carbon (AC) in view of its application as electrode material for electrochemical capacitors. Porous carbons are prepared by pyrolysis of chestnut seeds and subsequent activation of the obtained biochar. We investigate here two activation methods, namely, physical by CO2 and chemical using KOH. Morphology, structure and specific surface area (SSA) of synthesized activated carbons are investigated by Brunauer-Emmett-Teller (BET) technique and scanning electron microscopy (SEM). Electrochemical studies show a clear dependence between the activation method (influencing porosity and SSA of AC) and electric capacitance values as well as rate capability of investigated electrodes. It is shown that well-developed porosity and high surface area, achieved by the chemical activation process, result in outstanding electrochemical performance of the chestnut-derived porous carbons.

“…The most expected is to produce a universal sorbent with very good sorption properties [ 6 ]. The production of the activated carbon is based on various materials of organic origin, such as wood, hard and brown coal, polymers and waste from the wood industry, fruit stones and shells, various raw materials and materials of synthetic origin [ 7 , 8 , 9 , 10 , 11 , 12 ]. Apart from coal raw materials, various types of binders are used to produce activated carbons.…”

“…Apart from coal raw materials, various types of binders are used to produce activated carbons. As binders, coal tar, methyl cellulose, bentonite, clay, sugars, glycerine, glycol, various oils and many other substances are most often used [ 7 , 8 , 9 , 10 , 11 , 12 ]. They may also be waste substances from industrial production [ 13 ].…”

Activated carbons (ACs) are processed carbon-rich materials with a highly developed inner surface and significant porosity used for different media treatment in municipal and industrial plants. Activated carbon may be manufactured as powdered activated carbon (PAC), gritty activated carbon (in a form of raw angels grains) or granulated activated carbon (GAC). The production of the GAC is based on carbonaceous raw materials and various types of binders. The carbon mass is mixed with the binder and formed in cylindrical granules. The binder’s recognition is in a scientific literature side-topic and still needs wider examination. For many years GAC production have been concentrated on the possibility of using sodium carboxymethylcellulose (SCMC). Therefore, the aim of the research was to develop a new binder, in the available technology of granulated activated carbon production. Such binders were tested such as: tall oil (TO), sugar beet molasses (SBM), sodium carboxymethylcellulose (SCMC), SCMC using a verified technological process and SCMC with the addition of gas tar (GT). The conducted research shows that all the quality requirements were met by activated carbons with SBM as a binder. Additionally they showed very high adsorption properties. The manufacturing process was shorter in comparison to other tested binders and more efficient.
