摘要： In order to effect a reduction and a carburization to form Fe.sub.3 C to the highest possible degree in a relatively short time in an economical process, a treatment in two stages is effected in fluidized beds. The first stage is effected in a circulating fluidized bed system, in which the amount of solids circulated per hour is at least five times the weight of solids contained in the fluidized bed reactor and a major part of the iron content of the charge is pre-reduced. The remaining reduction and the partial or complete conversion to Fe.sub.3 C are effected in the second stage in a conventional fluidized bed. Water is condensed from the exhaust gas from the circulating fluidized bed system and that gas is strengthened by an addition of reducing gases and is reheated to the temperature which is required for the process. A part of the reheated recycle gas is supplied as a fluidizing gas to the conventional fluidized bed and the other part of the recycle gas is supplied as a fluidizing gas to the fluidized bed reactor of the circulating fluidized bed. The exhaust gas from the conventional fluidized bed is supplied as a secondary gas to the fluidized bed reactor of the circulating fluidized bed system.

摘要： A zinc- and lead-containing residue from a metallurgical plant is reprocessed by a thermal treatment in a circulating fluidized bed system. A major part of the heat demand is satisfied by a combustion of solid carbonaceous material in the fluidized bed reactor of the circulating fluidized bed system. A reducing fluidizing gas, which is virtually free of free oxygen, is fed to the lower part of the fluidized bed reactor. A solid carbon content of from 5 to 30% is adjusted in the fluidized bed in the lower portion of the fluidized bed reactor, which is supplied in its upper portion with oxygen-containing gases and in which CO.sub.2 is formed only at such a rate that zinc metal is not reoxidized. Substantially all solids are removed in a recycling cyclone from the suspension discharged from the reactor and the removed solids are recycled. The gas is cooled to a temperature at which zinc metal is oxidized to ZnO. The dust-like zinc compounds and lead compounds are removed from the gas.

摘要： In a process of simultaneously producing fuel gas and process heat from carbonaceous materials wherein the carbonaceous materials are gasified in a first fluidized bed stage and the combustible constituents left after the gasification are subsequently burnt in a second fluidized bed stage the throughput rate and the flexibility are increased in that the gasification is carried out at a pressure of up to 5 bars and a temperature of 800.degree. to 1100.degree. C. by a treatment with oxygen-containing gases in the presence of steam in a circulating fluidized bed and 40 to 80% of the carbon contained in the starting material are thus reacted. Sulfur compounds are removed from the resulting gas in a fluidized state at a temperature in the range from 800.degree. to 1000.degree. C. and the gas is then cooled and subjected to dust collection. The gasification residue together with the by-products which have become available in the purification of the gas, such as laden desulfurizing agent, dust and aqueous condensate, are fed to another circulating fluidized bed and the remaining combustible constituents are burnt there with an oxygen excess of 5 to 40%.
