The gas produced is withdrawn from the reactor (1) at a level located below the upper surface (10) of the carbonaceous material. Oxidant and/or thermal energy is supplied both (8, 9) above the surface (10) of the carbonaceous material in lump form and also (2) at a lower level in the reactor (1), located below the level of the gas outlet (5). <IMAGE>

Description

SPECIFICATION Gasifying carbonaceous material The present invention relates to a method and means for gasifying carbonaceous material to a gas mixture consisting primarily of CO and H2 and preferably having a total content of CO2 and H2 less than 12%.
It has long been known to gasify carbon in shaft furnaces and retorts and also to perform partial gasification in conjunction with coking. The drawback with the known methods is partly that it has been impossible to regulate the ratio between CO and H2 in the gas produced but, most important, that the gas also contained a number of undesirable substances such as hydrocarbon, alcohols, phenols and tar. The latter is obtained primarily because the gasification takes place at low temperature, i.e. at temperatures lower than 1 0000C and under reducing conditions.
In order to remedy these drawbacks, other methods have been developed where the gasification takes place under high temperature and oxidizing conditions, such as the Koppers Totzek method. However, this method has the disadvantage that, due to the thermodynamic equilibrium, the HzO content becomes relatively high which means that, to enable it to be used for reducing iron ore, for instance, the gas produced in this way must first be cooled, washed and then reheated. Furthermore, the chances of influencing the ratio between CO and H2 leaving the gasifier is extremely slight according to this method.
In accordance with the present invention there is provided a method of gasifying carbonaceous material to a gas mixture containing primarily CO and H2, which comprises 1) supplying carbonaceous material in lump form via a sluice arrangement to a reactor, preferably a shaft furnace, from above to a predetermined filling level, 2) withdrawing gas generated from the reactor through an outlet at a level below the upper surface of the carbonaceous material and 3) supplying oxidant and/or thermal energy both above the surface of the carbonaceous material and at a lower level in the reactor below the level of the gas outlet.
In the method of invention the gasification occurs at high temperature and under oxidising conditions and at the same time the gas initially produced passes a hot bed of carbonaceous, e.g.
coke or a cokelike, material, whereupon its content of H20 reacts with carbon to form H2 and CO. Furthermore, the method according to the invention enabies the CO/H2 ratio to be controlled since thermal energy can be supplied via plasma generators so that the ratio between H2O, CO2 and O2 in the oxidizing gas can be varied within wide limits. Preferably the ratios are controlled such that the CO/H2 ratio is less than 12%.
The invention will be described in more detail in the following with reference to two embodiments shown in the accompanying drawings, in which Figure 1 is a diagram of apparatus according to the invention, and Figure 2 shows an alternative embodiment of the apparatus shown in Figure 1 with respect to the lower part of the reactor.
The apparatus shown in Figure 1 and the alternative in Figure 2 consist of a shaft furnace 1, provided at the bottom with tuyères 2 and plasma generators 3, preferably located symmetrically around the shaft 1. These tuyères are provided with feeding means for oxidant such as oxygen (or gas containing oxygen), H20 or CO2 and possibly also powdered carbonaceous material. At a higher level the shaft 1 is provided with an annular drum 4 with a gas outlet 5 for the withdrawal of gas produced in the shaft. At the top the shaft 1 is provided with a gas-tight sluice arrangement 6 for the supply of carbonaceous material in lump form and also with a tuyère for connection of a plasma generator 7 and feed-in lances 8, 9 for oxidant.
Supply means 11, 12 for the supply of extra oxidant if necessary open into the shaft at a level between the upper surface 10 of the solid material in the shaft 1 and the annular drum 4. To enable the process to be driven with liquid slag or solid ash, the bottom part of the shaft 1 is provided with either a tapping channel 13 (Fig. 1) for slag or a rotating feed-out table 1 4 (Fig. 2).
The apparatus shown in the drawings operates as follows: To achieve the desired gasification the carbonaceous material in lump form is fed in, possibly together with a sulphur-binder e.g.
material in lump form containing Ca and/or Mg such as dolomite, via the sluice 6 into the shaft 1 to a predetermined level. Thermal energy is supplied by means of one or more plasma generators 3 and 7, respectively, at the same time as oxidant such as 02, CO2 or H20 is supplied via supply means 2 and 8, 9, respectively. The carbonaceous material in lump form, which may consist entirely or partially of coal, coke, pressed coke, peat, lignite, charcoal, wood or partially charred wood, etc., is thus subjected to high temperature under oxidizing conditions, whereupon the volatile constituents are released and react with the oxidant producing primarily CO and H2, while the non-volatile part is coked and forms a solid cokelike product in lump form.It is desirable that an excess of oxidant is added in order to prevent the formation of soot. The oxidant supplied above the surface of the carbonaceous material should preferably be sufficient at least to partially oxidise the volatile constituents of the carbonaceous material. Oxidant which has not reacted with the volatile constituents of the carbonaceous material will react lower down in the shaft 1 with the coke produced, forming additional CO and possibly H2O. The products formed in the upper part of the shaft, above the level of the annular drum 4, are thus products similar to coke which continue down through the shaft and a gaseous product consisting primarily of CO and H2 which leaves the shaft 1 through the annular drum 4, which is preferably more than 50 cm below the level to which the carbonaceous material is filled.The temperature on the surface of the granular material in the shaft may reach about 20000 C, while the gas leaving the shaft via the annular drum 4 has a maximum temperature of 1 5000 C. it is also possible to supply the necessary thermal energy by partial combustion of the carbonaceous material with oxygen instead of using a plasma generator. A number of tuyères 2 are placed around the lower part of the shaft 1, said tuyères being provided with either plasma generators or supply means for oxygen as well as supply means for oxidant and possibly powdered carbonaceous material and possibly also powdered material containing Ca and/or Mg to bind sulphur.At this level, preferably approximately 100 cm lower than the level of the annular drum 4, both the cokelike material falling down through the shaft and any powdered carbonaceous material blown in will be completely gasified. Any CO2 and H20 leaving the reaction zone just before the tuyère will react further up in the shaft with the lump material on its way down, producing primarily CO and H2. The gas produced, consisting primarily of CO and H2, will leave the shaft through the annular drum 4.
Preferably the gasification takes place under a pressure exceeding atmospheric pressure.
It may be advisable to supply slag-former at this level through the material lances 2, and to regulate the viscosity and melting point of the slag and/or sulphur absorbants containing Ca and/or Mg, such as dolomite powder. By controlling the composition of the slag in this way, it can be made suitable as a raw product for the manufacture of cement. It is also possible to replace the supply of heat via plasma burners at this level by partial combustion of the carbonaceous material by means of oxygen.
If it is desired to produce a liquid slag from the ash content so that it can be tapped off, the temperature in the reaction zone in front of the tuyères 2 in the lower part of the shaft should be maintained at above 1 6000 C. Preferably such liquid slag is granulated and rapidly cooled as it is being tapped off. When running the plant with solid ash which can be fed out as a solid by product, this temperature should be kept below 14000 C. Control of the supply of thermal energy enables these temperatures to be controlled.
The method described here for gasifying carbonaceous material offers considerable possibilities for regulating the H2/CO ratio in the gas produced, partly since the ratio of CO/H20 in the oxidant can be regulated and partly by sharing the heat supply between partial combustion and via plasma generators.
