PINTO-ALTAMIRANDA, Sania et al. Influence of Operational Parameters of Microwave-Assisted Hydrothermal Carbonization for the obtention of High Energetic Value Products: A Review. TecnoL. [online]. 2022, vol.25, n.54, e300.  Epub 28-Oct-2022. ISSN 0123-7799.  https://doi.org/10.22430/22565337.2265.

Agroindustry generates a large amount of organic waste, which is considered suitable biomass for energy use, one of the thermochemical conversion technologies that make it possible to obtain a product with a high energy value is hydrothermal carbonization, which can be microwave-assisted or conventional heating. The objective of this article is to collect information on the influence of the operating parameters in obtaining higher yields and carbon contents of hydrochar in the microwave-assisted hydrothermal carbonization (MAHTC) process, and in turn to demonstrate such influence of the parameters through a meta-analysis. For the meta-analysis, the collected bibliographic information was taken and evaluated through a generalized linear mixed-type model, which allowed concluding that temperature and time influence carbon content, while yield would be mainly influenced by time of reaction. In general terms, the reaction temperature parameter is highlighted as the most important factor in hydrothermal carbonization, since it determines the physicochemical properties of hydrochar, that is, with the information presented here, it is intended to encourage the use of agro-industrial residues to be transformed into products with high energy value, and thus provide a solution to the problem of climate change, promoting the sustainable development of the agricultural sector.
