“…The absorption peaks at 3328, 3321, and 3327 cm −1 (between 3200 and 3650 cm −1 ) mainly reflect the OH stretching vibration from carboxyl or hydroxyl groups of phenolic structures, alcohols, and carboxylic acids [ 48 ] ; the bands were less pronounced at HTC‐245°C, confirming the occurrence of dehydration reaction during the HTC process.…”

“…The absorption peak at 2899 and 2901 cm −1 (between 2500 and 3200 cm −1 ) for RF and PS samples are mainly caused by aliphatic CH bonds from alkyl groups. [ 49 ] The peaks at 2921 and 2850 cm −1 for FS samples are associated with CH symmetric and asymmetric stretching in CH 2 and CH 3 groups [ 48 ] ; these peaks become less evident at higher temperatures, which suggests demethylation reaction occurred and was more pronounced at 245°C.…”

“…Increasing temperature or CS blending ratio during HTC both could lower the H/C and O/C ratio of hydrochar, and the blending ratio had more significant influence on the H/C ratio, while temperature influenced the O/C ratio more obviously. This indicated that dehydration and decarboxylation may be the main reactions during the HTC process [ 21 , 35 ]. Generally, the lower H/C and O/C ratios were considered more beneficial for the further utilization as solid fuel due to lower energy loss during the combustion process.…”

“…Del desarrollo del presente trabajo de investigación, se detectó la importancia de los RSU, en la ciudad metropolitana de Chiclayo, así como su potencial energético, para lo cual se procedió a su caracterización térmica, mediante el muestreo, de residuos sólidos urbanos, y la correspondiente determinación de su poder calorífico inferior. También se revisó la producción de carbón mediante el proceso de carbonización hidrotermal, con rangos de producción de 0,56 kg de biochard, por cada 8 kilos de RSU, concentrando su poder calorífico de 7100 KJ/kg a 29 200 KJ/kg, evitando la emisión de gases efecto invernadero y de furanos y demás gases venenosos, así como genera trabajo de manera directa e indirecta, coincidiendo con lo expresado por DosSantos [20].…”
