Hydrothermal carbonization at high temperature gives various carbon materials, multi-walled carbon nanotubes, fullerenes, and carbon spheres with different nanotextures. In hydrothermal carbonization at a low temperature, the pressure is usually built up by water vapor and so depends on the volume of the autoclave and also on the amount of water.
