摘要: Abstract The influence of the variables biomass/water ratio (1.1–12.3%), temperature (150–250 °C) and residence time (3.2–36.8 h) on hydrothermal carbonization olive stone has been studied. implementation a design experiments – response surface methodology approach allowed process to be optimized in terms reactivity (solid yield) energy densification (increase higher heating value), importance each variable identified. Solid yield ranged between 30.95% 55.75% HHV from 22.2 29.59 MJ kg −1 . Interactions different involved were investigated provide more precise control overall so as satisfy any given requirement final hydrochar.
