摘要: Abstract Water hyacinth hydrothermal carbonization was studied under different temperature (160–250 C), time (30–120 min) and biomass/water ratio (10–50%) conditions. The research designed following response surface methodology, which very useful to infer interactions between variables develop models predicting the system behaviour with good accuracy. Output functions were solid yield, hydrochar C N content, as well their captures, heating value. It found that while most influential variable promoting HTC reactions, even biomass load decisive provide particular captures; based on these results, reaction mechanisms discussed. On other hand, 2D graphs allowed build scenarios in target properties might be achieved a wide range of dissimilar conditions, leading process optimization. study complemented by exploring N2 adsorption at 77 K, SEM micrography XPS analyses.
