“…In this work, the briquette sample produced from palm shells was found to have higher calorific value than briquettes from corncob and soybean stem. Previous researcher reported that the mixture of low rank coal and palm shell resulted 6438 kcal/kg (Sipatuhar et al, 2018), which is lower compared to this finding.…”

Indonesia biomass waste is a potential feedstock as a source of renewable energy since it can be converted into carcoal briquettes. However, the production of the briquettes using pyrolysis process using the agricultural waste was lacking. In this research, briquette was made from palm shells, corncob and soybean stem wood due to its high availability and have high cellulose content. The purpose of this research was to produce briquettes from three kind of raw materials by employing pyrolysis process and compared the characteristics. The briquette was made from different type of raw materials (palm shells, corncob and soybean stem) and the concentration of binder : 3-7 %. Pyrolysis was done at 500 °C, and 100 kg / cm2 of pressing pressure. Results showed that, the best charcoal briquette was achieved from palm shells by using 5% binder, which resulted 4,1% moisture content, 3.4% ash content, 15% volatile matter content, 77.5% carbon content, 7075 cal/g calorific value and 1.4 kg/cm2 compresive strength. It is found that the concentration of binder and raw material influenced the quality of the briquettes. In overall, the production of the briquettes by employing pyrolysis method could meet the standard.

“…Among these tehniques, binder utilization is more accessible for people especially the most vulnerable and poorest. However, in some cases, the binder is derived from food (Koteswararao et al, 2016;Sipahutar et al, 2017). This poses a number of problems as it is always the case when we use crop production or agricultural lands to produce energy (bioenergy).To avoid as much as possible these difficulties, we test clay as binder.…”

In this paper, the lower calorific value of corn cobs, palm kernel shells and tender coconut husks were determined and were respectively 24 760 J/g for corn cobs; 25 096 J/g for palm kernel shells and 16 550 J/g for tender coconut husks. Then, the mixture of different amount of corn cobs and palm kernel shells were made. The determination of their lower calorific value has shown that the mixture of 40% of corn cobs and 60% of palm kernel shells in mass has increased, 25 667 J/g, compared to the initial biochars.These values are lower compared to charcoal one's, 29 061 J/g.To bind the mixture as fuel briquettes, addition of 13.04% in sample total mass of clay is made. Binder decreases samples lower calorific value as 20 842 J/g for corn cobs, 13 527 J/g for tender coconuts husks and 21 377 J/g for palm kernel shells.For the mixture of 50% of corn cobs and 50% of palm kernel shells, lower calorific value decreases less compared to others.

“…Several researchers have carried out ash analyses using various techniques for different fuel samples. Most researchers analysed mainly for the percentage content of ash in fuel using conventional ash content test specified by ASTM D3174 standard 3 , 15 , 19 , 20 . To properly elucidate the role of the ash content of fuel during the application, a more detailed analysis is required.…”

“…However, these biomasses have been reported to have ash compositions that may weaken its usefulness for energy generation. Hence, the need to use biomass as a partial replacement for fossil fuel (coal) in energy generation 11,[13][14][15] . The ash content describes the product of incomplete combustion, which may be majorly minerals but could still contain some amount of organic or other oxidizable residues 16 .…”

The behaviour of ash of fuel affects its thermal efficiency when in use. The ash analyses of bio-coal briquettes developed from lean grade coal and torrefied woody biomass have received limited intensive study. Therefore, the present study aims at analysing the ashes of briquette made from lean grade coal and torrefied woody biomass using blended coal tar pitch and molasses as the binder. Bio-coal briquettes were produced from coal and torrefied biomass in various hybrid ratios. Ashing of various briquettes was done in a muffle furnace at 850 °C for 3 h. Mineral phases of the ash were identified using an X-ray Diffractometer (XRD), while the mineral oxides were obtained using an X-ray Fluorescence Spectrometer. The AFT700 Furnace was used with its AFT700 software to evaluate the ash fusion temperatures of the ashes. The XRD patterns look similar, and quartz was found to be the dominant mineral phase present in the raw coal and bio-coal briquettes. The SiO2 (57–58%), Al2O3 (19–21%), and Fe2O3 (8–9%) were the major oxides observed in the ashes. The final fusion temperatures of the ashes range from 1300–1350 °C. The compositions of the ashes of the bio-coal briquettes are classified as detrital minerals. It was concluded that the addition of torrefied biomass (≤ $$10\%)$$ 10 % ) and blended binder ($$\le $$ ≤ 15%) to coal gave a negligible impact on the ashes of the resultant bio-coal briquettes.
