摘要： 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.

摘要： A process for dehydrating water-containing organic solid material which comprises steps of introducing the material into a pressure vessel, applying saturated steam to said vessel to heat the material so that water in the material be removed and mixed with condensate of the steam to be exhausted from the vessel as a waste water. The process is characterized by a step of charging material of relatively large particle size at a bottom portion of the vessel and of relatively small particle size on the material of large particle size. The process makes it possible to dehydrate relatively fine particles of material by utilizing liquid form dehydration phenomemon.

摘要： Process for dehydrating water-containing organic solid material which comprises steps of introducing the material into a pressure vessel, applying saturated steam to said vessel to heat the material so that water in the material is removed and mixed with condensate of the steam to be exhausted from the vessel as a waste water. The waste water is transferred to another pressure vessel in which the material is not charged yet, the material being then charged into the vessel to carry out the same dehydrating steps. According to the process, a sufficient amount of heat exchange is performed between the material and the waste water so as to recover the heat in the waste water. Further, the waste water functions as a cushion for the material which is being thrown into the vessel so that the material can be protected from being pulverized.

摘要： In a non-evaporating dehydration of brown coal, the coal is crushed and classified into lumps and fine particles. The lumps of coal are subjected to a non-evaporating dehydration in which waste water is produced. The waste water is contacted with the fine particles of coal so that components which affect the COD value of the water are absorbed by the coal particles. The coal particles are then burnt to produce saturated steam which is used in the non-evaporating dehydration.

摘要： There is disclosed a process for dehydrating organic porous material such as brown coal. The process comprises steps of charging the material to a plurality of pressure vessels and filling at least one of the pressure vessels with water, carrying out a dehydration step by supplying steam to the vessel which is filled with water to heat the material therein while exhausting water from that vessel to thereby lower the water surface in the vessel so that the material therein is gradually exposed to the steam and water in the material is removed and mixed with condensed steam to form hot water, transferring the hot water from said first vessel to a substantially top portion of a second vessel while continuously supplying the steam to the first vessel until the second vessel is substantially filled with the hot water, and then expelling the hot water from a substantially bottom portion of the second vessel by the hot water which is transferred from the first vessel to the second vessel. As soon as the water in the first vessel is exhausted, the first vessel is separated from the other vessels and depressurized. An apparatus for carrying out such process is also disclosed.

摘要： An economical method for liquefying low rank coal is proposed. The method comprises steps of providing water-coal slurry by mixing crushed coal with water, heating the slurry under a pressure to a temperature which is lower than the saturated temperature under the pressure to thereby remove water from the coal with a result that coal content in the slurry be decreased, separating liquid in the slurry from solids, performing heat exchange between the separated liquid and the said pressurized water-coal slurry, then mixing the liquid with crushed coal to provide a further water-coal slurry, mixing the separated solids with a solvent to provide a fluid, evaporating water contents in the fluid, cooling the evaporated water to thereby condense it so as to recover volatile material, heating and pressurizing residual part of the fluid to a temperature and pressure suitable for liquefaction reaction with addition of hydrogen to obtain a liquefaction reactant then subjecting the reactant to a heat exchange with the water-coal slurry to cool the reactant to a temperature suitable for distillation, recirculating at least a part of the liquefaction reactant so that it is used at least a part of the solvent.
