摘要： In a process for the production of molten pig iron or molten steel pre-products and sponge iron from charging materials consisting of iron ore and, if desired, fluxes, direct reduction of the charging materials to sponge iron is carried out in a fixed-bed reduction zone, the sponge iron is melted in a meltdown gasifying zone under supply of carbon carriers as well as an oxygen-containing gas and a CO- and H.sub.2 -containing reducing gas is produced which is fed to the reduction zone, is reacted there and is drawn off as an export gas, and the drawn-off export gas is subjected to CO.sub.2 elimination and for the production of sponge iron is along with part of the reducing gas formed in the meltdown gasifying zone as an at least largely CO.sub.2 free reducing gas conveyed to a further reduction zone for the direct reduction of iron ore. In order to save investment costs incurred for the plant and to increase productivity, part of the reducing gas produced in the meltdown gasifying zone is branched off and fed to the further reduction zone while avoiding CO.sub.2 elimination.

摘要： A process for the direct reduction of particulate iron-oxide-containing material by fluidization. A synthesis gas is introduced as a reducing gas into several fluidized bed zones consecutively arranged in series for the reducing gas. The reducing gas is conducted from one fluidized bed zone to another fluidized bed zone in counterflow to the particulate iron-oxide containing material. In order to reduce operating costs and, in particular, the energy demand, the temperature of the iron-oxide-containing material is adjusted in the first fluidized bed zone to be either below 400° C. (and, preferably, below 350° C.), or above 580° C. (and preferably about 650° C.), or to a temperature ranging from 400° C. to 580° C. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is adjusted to be below 400° C., the temperature range in the following fluidized bed zone between 400° C. and 580° C. is passed through within a period of 10 minutes and, preferably, within 5 minutes. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is adjusted to be above 580° C., the temperature range in the first fluidized bed zone between 400° C. and 580° C. is passed through within a period of time of maximally 10 minutes and, preferably, 5 minutes. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is adjusted to be in the range of from 400° C. to 580° C., the iron-oxide-containing material remains within that temperature range for a maximum of 10 minutes and, preferably, 5 minutes, and the material is passed on into the following fluidized bed zone immediately after having reached the desired temperature.

摘要： In a process for reducing iron-ore-containing particulate material in at least a two-stage process, reducing gas is conducted through at least two reaction zones consecutively arranged in series and formed by a moving particulate material and the particulate material passes through the reaction zones in reverse order to the reducing gas, with the particulate material being heated in the reaction zone arranged first for the particulate material and being reduced in the further reaction zone.In order to achieve a maximum preheating temperature without any formation of magnetite, the reducing gas added to the first reaction zone is conditioned such that no or hardly any reduction takes place, although for the particulate material a preheating temperature within the fringe range of starting a reduction is achieved, whereby either the degree of oxidation of the reducing gas is increased or the temperature of the reducing gas is decreased or both measures are carried out jointly and whereby, in the reactor zone arranged second for the iron ore, a temperature level of at least about 600° C., preferably in the range of between 600 and 700° C., in particular of between 620 and 660° C., is adjusted and the iron-oxide-containing material is reduced to wuestite (FIG. 1).

摘要： In a process for the direct reduction of particulate iron-oxide-containing material by fluidization, a synthesis gas is introduced as a reducing gas into several fluidized bed zones consecutively arranged in series. The reducing gas is conducted from one fluidized bed zone to another fluidized bed zone in counterflow to a flow of particulate iron-oxide containing material through the fluidized bed zones. In order to reduce operating costs and, in particular, the energy demand, various process parameters are varied according to the temperature of the iron-oxide-containing material in the first fluidized bed zone being adjusted to be below 400° C. (and, preferably, below 350° C.), above 580° C. (and preferably about 650° C.), or to a temperature within the range of from 400° C. to 580° C. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is maintained to be below 400° C., the temperature of the iron-oxide-containing material in the following fluidized bed zone is passed through the temperature range between 400° C. and 580° C. within a period of 10 minutes and, preferably, within 5 minutes. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is adjusted to a temperature above 580° C., the temperature range of between 400° C. and 580° C. in the first fluidized bed zone is passed through within a maximum period of time of 10 minutes and, preferably, 5 minutes. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is adjusted to be within the range of from 400° C. to 580° C., the iron-oxide-containing material remains in the first fluidized bed zone within that temperature range for a maximum of 10 minutes and, preferably, 5 minutes, and the material is then passed on into the following fluidized bed zone immediately after having reached the desired temperature.

摘要： A method of and apparatus for charging fine-grained ore into a reactor pressure vessel through which process gas flows. The heated ore at first is introduced into a conveying pressure vessel, is pressurized within the same by compressed gas and subsequently is conveyed into the reactor pressure vessel through a conveying duct by aid of the compressed gas. In order to ensure favorable utilization of the reactor pressure vessel under uniform stress and to safeguard troublefree progression of reduction while directly charging the ore, a portion of the ore is introduced into at least one further conveying pressure vessel and is pressurized within the same also by compressed gas. Charging of the ore into the reactor pressure vessel is effected continuously by alternately feeding once from the one conveying pressure vessel and subsequently from the other conveying pressure vessel. The compressed gas is taken from the process gas as a quantitative or as a component portion of the process gas and is fed back to the same along with the ore.

摘要： A method for the direct reduction of particulate iron-oxide-containing material. The method is carried out in a shaft furnace, wherein reformed gas from a reformer is fed as reducing gas to a reducing zone of the shaft furnace, the directly reduced ferrous particles are discharged from the shaft furnace and the top gas forming during reduction is extracted from the upper section of the shaft furnace. A hydrocarbon-containing gas is injected into the shaft furnace. Natural gas is separated into a first fraction enriched with low hydrocarbons and a second fraction enriched with higher hydrocarbons. The first fraction is conducted through the reformer and the second fraction is fed into the shaft furnace.

摘要： With a process for the direct reduction of particulate iron-containing material by fluidization, reformed gas, at least partially freed from CO.sub.2, is supplied to a fluidized-bed reduction zone as a reducing gas and is carried off from the same as a top gas and at least a portion of the top gas together with reformed gas is utilized for direction reduction. To economize on parts of the plant that are impinged on by reducing gas and in order to achieve savings in terms of heating costs, CH.sub.4 and N.sub.2 are, in addition to CO.sub.2, at least partially removed by adsorption, from 50 to 100% of the reformed as and 0 to 100% of the top gas, and the tail gas removed from the reformed gas and/or the top gas by adsorption is utilized as a heating gas.
