“…Ayoe Benk [9] stated that the improvement in the quality of asphalt as a binder is due to the increase in asphaltene by the action of oxygen in the air, therefore, high-strength coal with a tensile strength of 50.45 NM/m 2 was obtained using air-oxidized CTP blended with phenolic resin as a coal binder and cured at 200 • C for 5 h. In addition, the air oxidized CTP can also be used as a raw material for preparing materials such as mesophase carbon microspheres and carbon fibers [10,11]. Above, CTP can be used effectively after air oxidation.…”

Coal tar pitch (CTP) is abundant and widely used, but its properties will be affected due to oxidation aging during storage. In this study, CTP was oxidized by simulating the air oxidation process, and the change of chemical structure has been analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and both gas chromatography and mass spectrometry (GCMS). The effects of the oxidized and unoxidized CTP co-carbonization with coal on the polycyclic aromatic hydrocarbons (PAHs) emission were detected by GCMS. The small and medium-molecule aromatic substances were reduced during CTP oxidation, while the intermolecular condensation reaction increased the macromolecules content. The catalytic can effectively facilitate the dehydrogenation and condensation reaction of CTP and the entry of oxygen molecules, which leads to the increase of oxygen-containing groups and the decrease of PAHs. Compared to the raw CTP, the catalytic oxidized CTP significantly reduced the emissions of toxic PAHs during the co-carbonization with coal. A possible catalytic mechanism of CTP catalytic oxidation is proposed.

“…However, the reactivity of the biocoke (20.8%) is much higher than that of the coke (11.2%). Table 3 also shows that replacement of torrefied lignin (TL) with torrefied demineralized lignin (TDL) does not affect the mechanical strength of the biocoke but lowers its reactivity from 20.8% to 16.7% and increases the microporous surface area by 35 m 2 /g. These results indicate that there is no evident relationship between the microporous surface area of the biocoke and biocoke reactivity.…”

“…The addition of air blown coal tar pitch and phenolic resins (50:50 wt/wt) as binder to coke breeze and anthracite have produced briquettes with high tensile strength even at 950°C [16,17]. Collin et al [18] carried out co-carbonization of coal with pitches and waste plastics, including a phenol formaldehyde resin, and it was found that the highest yield of non-volatile compounds was obtained with the reactive pitch containing phenolic resin.…”

Metallurgical coke makers could reduce carbon emissions and material costs by introducing waste lignin in coke oven charges. Two approaches have been studied here to increase the use of lignin in the preparation of metallurgical coke: lignin demineralization with H2SO4 and lignin blending with a low rank coal using phenolic resin as binder. The biocoke obtained after carbonization at 1000°C from the

“…Besides tapioca starch as a binder in a briquette making process, there were some options showing another material used as a binder. Following [9] applied the blend of coal tar pitch with phenolic resin in coke breeze briquettes. The result showed that their strength increased from 50.45 MN m -2 to 71.85 MN m -2 .…”

The current research aimed to increase the calorific value of woody cutting waste briquette with paper waste pulp as binder. There were three different binder variation used in this study, they are 5 %, 10 %, and 15 %. To create a briquette, a cylindrical iron mold with diameter of 3.5 cm and height of 3 cm and a hydraulic press with 2 t power were applied. The physical characteristics of the combination woody waste briquette and paper waste pulp, such as moisture content, ash content, volatile matter and carbon fix were examined using proximate analysis. The calorific value of briquetted fuel was tested by bomb calorimeter. The combustion test was performed to determine the combustion characteristic of briquettes, for example initial ignition time, temperature distribution, and combustion process duration. The general result shows that the calorific value of briquette stood in the range of 4 876 kCal kg–1 to 4 993 kCal kg–1. The maximum moisture content of briquette was 5.32 %. The longest burning time was 105 min.
