A high moisture porous organic solid is dewatered by the steps of (1) heating the high moisture porous organic solid in a fluid medium having an elevated temperature and a high pressure, thereby reducing the moisture of the solid, (2) starting to compress the porous structure of the solid by mechanical means, while maintaining the temperature and the pressure of the surrounding fluid medium the same as in the final stage of step (1), and (3) lowering the pressure of the surrounding fluid medium while maintaining the mechanical compression of the solid, whereby the quality of the porous solid, such as apparent density and calorific values of moist solid per weight as well as per volume are considerably improved.
