    Abstract: PURPOSE:To efficiently transport and store org. sludge by fluidizing a caked org. sludge at a specified temp. and the pressure above the saturated steam pressure at that temp., transporting and storing the fluidized material. CONSTITUTION:A concd. org. sludge is introduced into a dehydrator 1, and the dehydrated sludge is introduced into a fluidizer 2 which is a heat-exchange reactor. A heating medium is introduced from a line 15, and the org. sludge is preheated in the fluidizer. The preheated sludge is supplied to a line 16 in the fluidizer and heated to the reaction temp. by the heating medium discharged from a line 21. In this case, the reaction temp. is controlled to >=150 deg.C, and the reaction pressure is adjusted above the saturated steam pressure at the reaction temp. The fluidized material is introduced into a cooler 3 and cooled by the heating medium from a line 20, and the heating medium is passed through the line 15 to heat the fluidizer 2. The fluidized material is then transferred to the treating equipment by a feed pump 6 or transported to the remote sludge treating equipment.

    Abstract: PURPOSE:To provide an easy and efficient process for producing a heavy oil-like substance by liquefying microalga capable of fixing carbon dioxide gas by photosynthesis. CONSTITUTION:Microalga capable of fixing carbon dioxide gas by photosynthesis is maintained under a high temperature and pressure condition in the presence of an alkaline substance and an aqueous medium. The microalga is liquefied to a heavy oil-like substance by this treatment to obtain a liquid fuel usable as a substitute for fossil fuels.

    Abstract: PURPOSE:To provide a method by which a cell which accumulates oil or fat is liquefied simply and effectively to give a substance like heavy oil and simultaneously bring the liquefaction product into a state with good phase separation properties. CONSTITUTION:A cell which accumulates oil or fat is kept at high temp. and pressure in the pressence of an aq. medium to thereby be liquefied to give a substance like heavy oil. The conditions of the liquefaction are controlled so that the liquefaction product contg. the substance is brought into a state with good phase separation properties.
