摘要： Provided is a carbonizing furnace capable of improving combustion efficiency of combustible gas generated by combustion of organic waste and of improving carbonization efficiency of organic waste by appropriately controlling the temperature of carbide. Provided is a pyrolytic furnace in which heating gas can be suppressed from outflowing to the outside from a gap between the upper surface of the body part of the pyrolytic furnace and the outer circumferential surface of a reaction tube where a pyrolysis reaction between carbide and a gasification agent is caused, and in which the temperature of a region where the pyrolysis reaction is caused can be suppressed from being reduced. Provided is a water gas generation system which improves thermal efficiency without using a dedicated heat source for generating water steam to be used as a gasification agent for carbide, promotes a pyrolysis reaction, and thereby, achieves the excellent heat efficiency. Provided are a hydrogen gas generation system and a power generation system which use water gas generated by a water gas generation system including a carbonizing furnace and a pyrolytic furnace and which have excellent productivity. Provided is a carbonizing furnace which improves combustion efficiency by controlling the supply amount of air being supplied to the carbonizing furnace according to the temperature of combustion gas in the carbonizing furnace, and which improves carbonization efficiency by controlling the discharge amount of carbide to be discharged to the outside according to the temperature of carbide or the deposit amount of organic waste in the carbonizing furnace, to make the temperature of carbide appropriate, and by controlling the temperature of air being supplied to the carbonizing furnace. In addition, provided is a pyrolytic furnace which blocks outflow of heating gas or water gas by providing seal portions at the attachment positions of a body part, a reaction tube, and a water gas outlet part, etc. of the pyrolytic furnace, and which maintains a pyrolysis reaction temperature by providing a pyrolysis promoting mechanism to the reaction tube. Provided is a water gas generation system which has excellent thermal efficiency and in which a combustion gas flow path is formed so as to allow combustion gas generated by a carbonizing furnace to flow through a carbonizing furnace, a pyrolytic furnace, a steam superheater, a steam generator, a dryer, and the like. Provided is a hydrogen gas generation system or a power generation system formed by combining the water gas generation system with a hydrogen purifying apparatus or a power generation equipment.

摘要： A process and apparatus are provided for reducing content of tar in a tar containing syngas. The process includes contacting the tar containing syngas with a molecular oxygen containing gas in a first reaction zone to produce a gas mixture. The gas mixture is passed through a heat treatment zone maintained at a temperature between about 900° C. to about 2000° C. for a contact time of about 0.5 to about 5 seconds. In this aspect, at least a portion of the tar undergoes at least partial oxidation and/or cracking to produce a hot syngas.

摘要： Used as a heat transport medium to be transported with a fluid that is liquid in an operating temperature range is a medium in which a latent heat storage material is penetrated in a porous material, wherein the latent heat storage material is incompatible with the fluid and has a melting point within the operating temperature range, and the porous material has a liquid repellency to the fluid, an affinity for the latent heat storage material, and a sponge hardness of not more than 50. This achieves stable heat transport with a high heat conversion efficiency even by circulating the medium through a pipeline over a long period of time. The porous material may have continuous pores. The porous material may have a void ratio of not less than 50%. The porous material has an apparent density of about 0.05 to 0.5 g/cm3. The ratio of the latent heat storage material is about 100 to 5000 parts by weight relative to 100 parts by weight of the porous material. The porous material may contain a water-repellent lipophilic resin. The porous material may have a polyorganosiloxane skeleton.
