Papaya peels as source of hydro char via hydrothermal carbonization

Papaya peels was converted into hydro char via hydrothermal carbonization (HTC) and used as adsorbent for methylene blue removal. The carbonization of the papaya peels was executed at six different temperatures ranging from 150 °C to 200 °C with 50 °C interval with reaction time of 120 minutes mainly to study the effect of the carbonization temperature on the hydro char formed via HTC. The hydro char produced was assessed in terms of mass yield,...
