“…Ekpo et al (2016) demonstrated that increasing temperature, highest levels of Ca and Mg in the hydrochar were obtained with the addition of NaOH, formic acid and acetic acid in the HTC of swine manure. Results presented by Reza et al (2016) from the HTC of glucose in a saline medium corroborated with the previous study showing increased nutrient concentrations (N, Fe and P) in hydrochars produced at higher temperatures. In recent work done by our research group, the effect of reaction time, temperature and the presence of phosphoric acid on phosphorus incorporation in hydrochar produced by the HTC of vinasse and bagasse mixture was evaluated (Melo et al, 2016).…”

“…Phosphorus immobilization has also been observed in the HTC of animal manure and attributed to the presence of metal cations such as aluminum, calcium, magnesium and iron, which led to the formation of insoluble phosphates such as Ca 3 (PO 4 ) 2 and Mg 3 (-PO 4 ) 2 in the hydrochar (Heilmann et al, 2014). Reza et al (2016) reported the immobilization of phosphorus in the hydrochar when glucose was hydrothermally carbonized in the presence of NH 4 H 2 -PO 4 , and suggested that phosphorus is chemo-adsorbed on the surface of the hydrochar. In this work, the phosphorus was probably immobilized in the hydrochar due to the formation of precipitates.…”

“…Figure 2 shows the FTIR spectra for Cs, Cs-SO 3 H and Cs-PhSO 3 H catalysts. All of them show a band around 1590 cm −1 , which can be attributed to the stretching of the C=C bonds formed as a consequence of the carbonization process (Zong et al 2007;Toufiq Reza et al 2016). Besides, a broad band located at 3440 cm −1 is found, which is associated with the -OH stretching mode.…”

“…La Figura V.13 muestra los espectros FTIR para los catalizadores Cst, Cst-SO3H y Cst-PhSO3H. Todos ellos presentan una banda alrededor de 1590 cm -1 que puede atribuirse al estiramiento de los enlaces C=C formados como consecuencia del proceso de carbonización (Reza, Nover, Wirth, & Coronella, 2016). También se evidencia una banda ancha ubicada a 3440 cm -1 , que está asociada con el modo de estiramiento -OH.…”
