The current agroindustrial development is characterized by generating high volumes of waste, mainly waste lignocellulosic biomass. These are mainly used for composting and for generating heat by combustion, and alternately used for the production of activated carbon. A carbonization option for biomass with high moisture content is hydrotreatment at subcritical water conditions (𝑇𝑐𝐻2𝑂 = 374 ° 𝐶). The solid thus obtained is called hydrochar which is used as a precursor of activated carbon. In this research activated carbon is prepared from spend ground coffee hydrochar formed and unformed. carboxymethylcellulose was used as a binder for preparing shaped before activation. In this investigation it was considered to start from hydrochar because the hydrotreatment procedure through which it is prepared is appropriate for biomass with high moisture content, as with spend group coffee, also because the particle size of the bean is well adjusted for this procedure. Hydrothermal treatment conditions to prepare the hydrochar were 220 ° C and 240 ° C for times of 12 to 48 h and ratio g borra / mL water 1/10 and 3/10. The chemical characterization by FTIR and Raman, textural by SEM and gas adsorption (N2 at -196 ° C and CO2 at 0 ° C) and the proximate analysis of the hydrochar, indicated that the hydrotreatment resulted in a carbonaceous structure with more graphite character and less structural disorder due to the presence of heterogeneous groups such as aliphatic, C-O-C, -OH, the higher the temperature and the time of hydrotreatment. Likewise, it was determined that the spend group coffee / water ratio affected the properties of the hydrochar. Since the temperatures of obtaining hydrochar are relatively low to stabilize the structure of the biomass for subsequent activation, it was decided to choose the hydrochar that had the greatest graphite character and less heteroatoms, since the presence of such defects can affect the mass yields of activated carbon to be obtained. This is how the hydrochar prepared at 240 ° C, 48 h and the ratio of g / l water / mL = 1/10 was selected for subsequent activation. Activation is made by the physical method, with steam at temperatures between 600 and 800 ° C; and by the chemical method, with H3PO4, between 400 and 600 ° C; and in all cases 1 and 2 h of activation. Chemical activation area it not developed, while the physical activation developed surface area between 360 m2 g-1 to 730 m2 g-1, and essentially mesoporous porosity, compared with direct activation of the batt that essentially developed microporosity. The results show that as hydrotreating prior to activation step is an alternative for obtaining porous materials with favorable yields in mass, and the porosity which can develop is essentially mesoporous. The hydrothermal treatment, prior to the activation step takes advantage of the spend grounds coffee high humidity and particle size that is generated, so that processes conditioning biomásico precursor, such as drying and grinding, are eliminated factors determinants for energy savings. The porosity of activated carbon from hydrochar of spend group coffee allows to modulate the porosity towards the conformation of mesoporos, while the activation of spend group coffee, using as a previous step the pyrolysis, develops essentially a microporous structure. In general, the preparation of activated carbon from hydrochar of spend grounds coffee, can assess this waste generated in high volumes, with moisture content and particle size, important characteristics for the hydrothermal procedure.
