摘要： PROBLEM TO BE SOLVED: To provide a method for producing a fuel from a biomass, in more detail, a method for producing the fuel such as ethanol and methane by using minute algae, and weeds and crops as raw materials, degrading the raw materials in supercritical water to reduce the molecular weights, and carrying out alcohol fermentation of the degraded raw materials by alcohol yeast or methane fermentation thereof by gasification bacteria. SOLUTION: This method for producing the fuel from the biomass comprises collecting the biomass, pulverizing the collected biomass, adding water to the pulverized product to form a slurry, keeping the resultant slurry in the subcritical state or the supercritical state to degrade polysaccharides included in the biomass to saccharify the polysaccharides, and fermenting the saccharified product to produce the objective fuel.

摘要： PROBLEM TO BE SOLVED: To provide a method with which gasses produced from coal or oil is refined into the ones useful, e.g. as fuel for power generation at low cost by removing carbon monoxide from a used absorbent for desulfurization (i.e., removal of sulfur compound(s) from the gases) before it is regenerated, in order to control deterioration of the absorbent. SOLUTION: This method comprises steps of (1) vapor/liquid contacting between (A) gases produced by gasification of coal or oil and (B) an absorbent solution for absorbing sulfur compound(s), to remove the sulfur compound(s) Z1 from the component A (desulfurization), (2) removal of carbon monoxide Z2 , also present in the component A, from the used component B which has absorbed Z1 and Z2 during the above step, (3) regenerating the component B, from which the compound Z2 has been removed by the above step, under heating to separate and discharge the regeneration gas containing the compound(s) Z1 , and (4) recycling the regenerated component B back for desulfuization of the component A. Removal of the compound Z2 from the used component B is effected by, e.g. keeping the used component B under a vacuum lower than the desulfurization pressure to separate and discharge the compound Z2 and other gases dissolved in the component B as the off gas.

摘要： PROBLEM TO BE SOLVED: To improve heat efficiency by a method wherein heat is recovered from a formed gas before purification treatment by a heat exchanger, and then, after hazardous substances in the formed gas are removed by bringing the formed gas into gas-liq. contact with a cleaning liq. or an absorbing liq., it is heated again with the recovered heat in the heat recovering process. SOLUTION: Heat of a gas Al before treatment is recovered by means of a heat exchanger 3 and a gas A4 after purification treatment is heated with this heat to form a gas A5, which is fed into e.g. a gas turbine G/T of a complex power generation system. In addition, before H2 S in the gas is absorbed and removed, impurities in the gas is removed in a cleaning tower 4. Then, the gas is heated in a heater 9 and, thereafter, COS in the gas are converted into H2 S by means of a convertor 10. In this instance, the temp. condition in a heat recovery process is set under a condition where ammonium chloride does not separate out and stuck on the heat transmission face of a heat exchanger 3 and this setting is performed through a preheating process wherein the gas A4 introduced into the heat exchanger 3 is heated in advance in a heat exchanger 11 and a heater 17.

摘要： PROBLEM TO BE SOLVED: To provide the subject refiner capable of easily removing sulfur compounds and other impurities from a produced gas obtained by gasifying coals, etc., by bringing the gas into gas-liquid contact with an absorbent liquid and followed by with a scrubbing liquid and converting carbonyl sulfide in the gas into hydrogen sulfide. SOLUTION: This refiner operates as follows: passing a produced gas obtained by gasification of coals, heavy weight oils, etc., through a converter 5 provided with a catalyst comprising titanium oxide and excluding any additives with a strong affinity for impurities in the gas and adapted to convert carbonyl sulfide in the gas into hydrogen sulfide; scrubbing the resultant gas by bringing it into gas-liquid contact with a scrubbing liquid in a scrubbing tower 7; bringing it into gas-liquid contact with an absorbent liquid in a desulfurizing tower 21; and thus refining the produced gas while reducing a capacity of a heat exchanger serving to cool and re-heat the produced gas for removal treatment of the impurities.

摘要： PROBLEM TO BE SOLVED: To effectively recover thermal energy and to reduce the quantity of water by providing a means for recovering heat from flue gas generated in a boiler and passing through an absorption tower for removing sulfur oxide from the flue gas, and from absorbent slurry in the absorption tower. SOLUTION: In a thermal power system, condensate is fed from a condenser 11 into a heater 12 by a pump 12, and thus heated condensate is introduced into a heat recovery means 61 in a flue gas desulfurizing device 57 through a line 62, and is heated by flue gas or absorbent slurry. Thereafter, it is introduced into an air breed water supply heater where it is heated and then fed into a boiler as boiler supply water. The heat recovery means 61 is a heat- exchanger for exchanging a heat between the boiler supply water fed through the line 62 and the fuel gas and/or the absorbent slurry in the absorbent tower in the desulfurizing device 56 so as to recover heat from untreated flue gas before the latter makes contact with the absorbent slurry, or from the flue gas and the absorbent slurry after the liquid and gas contact.
