Producing Animal Originated Charcoal Production and its Characterization Analysis Compared to Brown Coal

On place research was conducted on a farm where cows were fed by a mixture of traditional pasturing and feed supply. Pyrolysis was carried out directly on the farm to produce a ready-to-use biochar product. The product of biochar after pyrolysis was mixed with an organic adhesive dopant into 100 gram processed products for commercial use. This processed product was analyzed by elemental analysis, proximate analysis, TGA, FTIR and electron paramagnetic resonance spectroscopy. Data from these analyses was compared to those of brown coal Aduunchuluun, which is originally from the same place as the bio waste. Heavy elements content in biochar such as silicon, aluminium, sulphur, etc. is significantly less than compared to the brown coal. TGA and DTG analysis on the biochar product showed a total weight loss of 0.87%, where nearly 0.26% of the moisture was released in the temperature interval of 30 - 300°C, 0.46% of devolatilization occurred in 300 - 600°C, and 0.15% of mass loss in combustion reaction in 600 - 700°C. The residue after the thermal processing was minimal and consisted of hemicellulose and cellulose after volatilization. From the FTIR analysis, we see a disappearance of hydroxyl group vibration around 3400 cm -1 and carbonyl C=O stretching 1733 cm -1 from the biochar product compared to brown coal. The aromatic absorption near 1600 cm -1 is shifted to 1392 cm -1 in biochar. EPR spectrum of bio product consists of two lines, broad and narrow in the resonance field of ≈ 3500 Gs. Corresponding g-factor of narrow line and broad line 2.0022. It is calculated the spin numbers in biochar sample, that is compared to brown coal related data.
