及び装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides solid carbon in a fluidized bed reactor in which solid particles carried away by the gas exiting from the upper part of the fluidized bed are separated and returned to the lower part of the reactor. The present invention relates to a method and apparatus for gasifying materials.

する方法及び装置を提供することである。 It is an object of the present invention to provide a method and apparatus for oxidizing solid carbonaceous materials such that the free oxygen of the oxygen-containing gas is used primarily for the oxidizing gasification of solid particles formed as a result of pyrolysis.

による小粒子の同伴である。 An essential dilemma in the gasification of solid materials is that the CO 2 and H 2 O produced in the oxidation phase can be converted to a kinetically slow reaction with solid carbon, i.e. CO 2 +C(D).
→Reduction by 2CO and H 2 O + C → CO + H 2 . The earliest gasifiers were so-called countercurrent gasifiers, in which the material to be gasified was fed from the top of a bed of solid gasified material and the oxidizing agent was fed from the bottom of the bed. In these so-called static bed gasifiers, the material moves downward and is first pyrolyzed at low temperatures in a reducing atmosphere. The temperature in the lower region is about 1000° C. and there is a lot of reducing carbon surface/volume, so that efficient reduction of the gas phase is achieved in that region. Known disadvantages of these types of vaporizers are tar compounds in the gaseous products as well as the entrainment of small particles by the gaseous products.

置の典型的な問題である。 In co-current gasifiers, the material to be gasified and the oxidant are brought to the front of the reactor and a significant amount of pyrolysis gas is oxidized to CO2 and H2O . The remaining solid carbon must be gasified in these reactors by the slow reduction reaction described above. Therefore, significant CO 2 and H 2 O content of the gaseous product, ie significant carbon loss, is a typical problem in conventional co-current gasifiers.

び大きな投資コストの問題である。 In a two-zone gasifier, the disadvantages of the above type of gasifier are avoided by splitting the gasification into two separate reactors and by first pyrolyzing the material to be gasified. The solid material remaining after pyrolysis is gasified in a separate reactor and the flue gas is carried into the pyrolysis reaction. Gasification thus takes place in two downstream connected reactors. The disadvantage of this two-zone gasifier is the problem of flow technology and high investment costs.

Here, the fluidized bed is divided into two zones by intermediate baffle means, the temperature of the lower zone being suitable for combustion or gasification, and the temperature of the upper zone being most suitable for sulfur absorption. It will be adjusted so that The fuel or material to be gasified is introduced into the lower zone of the reactor where some free oxygen is present.
The pyrolyzed hydrocarbons are then mainly oxidized,
Forms CO 2 and H 2 O. This forms a lot of residual carbon that must be gasified by the hydrocarbon combustion products.

てコントロールされる。 The present invention relates to the operation related to the two reactor gasifier described above being solved as follows.
That is, the inlet for the material to be gasified is placed above the air nozzle (3 to 6 m), elevated in an area with a low content of free carbon. The pyrolysis gases thus formed near the feed inlet are not oxidized but are thermally decomposed into short-chain hydrocarbons, which further react with CO 2 and H 2 O rising from the bottom of the reactor. These so-called reduction reactions occur in the upper part of the gasification reactor, where the residence time of the gas (2-20
seconds) and temperature (above 900°) are chosen such that the gaseous products eventually reach near thermodynamic equilibrium. The energy required for the reduction reaction is obtained from the oxygen oxidation reaction taking place in the lower part of the reactor. In order to apply excessively high temperatures, the temperature difference between the reduction and oxidation zones of the reactor is adjusted by circulating carbon and a chemically inert material such as sand through both reactors. Since the oxidation and reduction zones are located in the same reactor, this circulation is controlled by adjusting the particle size and amount of inert material such that an appropriate portion of the material is air-transferred in the gas flow region where it is used. It can be done easily. In this case, the solid material separated in the gas purifier and returned to the lower part of the reactor first passes through a hot oxidizing zone and is then cooled as it passes through a reducing zone. The mass flow rate of the inert material circulation depends on the amount of circulating material and the sintering temperature of the ash to be gasified, with a maximum temperature in the oxidation zone of 970 °C ~
Below 1200℃ and maximum temperature after reduction zone is 70~120℃
It is controlled by controlling the temperature to be below ℃.
酸化帯域及び還元帯域間の温度差を上記範囲に
保つために、循環材料は反応器のガス内に500〜
1000g/モルの固体材料があるように循環されな
ければならない。この様に微細砂(10μm<粒子
サイズ(dp)<400μm)及び不活性石炭の多量
な流れが分離器から反応器の下部に戻されなけれ
ばならない。 In order to keep the temperature difference between the oxidation and reduction zones within the above range, the circulating material is placed in the reactor gas at
It must be circulated such that there are 1000 g/mol of solid material. Thus a large flow of fine sand (10 μm<particle size (dp)<400 μm) and inert coal must be returned from the separator to the bottom of the reactor.
