摘要:
Method and equipment for producing coke (PC) during indirectly heated gasification, in which coal particles are supplied to a gasification reactor (1) and process gas (P) supplied during the gasification is reduced in it to synthesis gas (S), whereby the synthesis gas (S) is removed from the gasification reactor (1). The method is distinguished in that at the same time a gasification takes place, a coking of coal takes place in an inner reactor (4) arranged inside the gasification reactor (1), that the inner reactor (4) is indirectly heated, that coke (PC) and combustible gases are produced in the inner reactor (4) during the coking, and that the combustible gases are used for the indirect heating in the gasification in the gasification reactor (1).

The present invention relates to a method for producing coke (PC) during indirectly heated gasification, in which coal particles are supplied to a gasification reactor (1) and process gas (P) supplied during the gasification is reduced in it to synthesis gas (S), whereby the synthesis gas (S) is removed from the gasification reactor (1). The invention also relates to equipment for carrying out the method. The method in accordance with the present invention is distinguished in that at the same time a gasification takes place, a coking of coal takes place in an inner reactor (4) arranged inside the gasification reactor (1), that the inner reactor (4) is indirectly heated, that coke (PC) and combustible gases are produced in the inner reactor (4) during the coking, and that the combustible gases are used for the indirect heating in the gasification in the gasification reactor (1).
摘要:
The present invention concerns a method for producing hydrogen from biomass, wherein said method comprises the stages of drying of the biomass, gasification of the biomass, and water gas shift reaction. The invention also concerns a equipment for conducting the method of the present invention. It is essential to the present invention that the method comprises the additional stages: of subjecting the outgoing gases (CO 2 , N 2 and H 2 O) from the gasification stage to a first heat exchange, wherein the outgoing gases (CO 2 , N 2 and H 2 O) are cooled, of evaporating water with heat from outgoing gases, of subjecting the steam to heat exchange wherein the steam is heated, of reducing the steam to synthesis gas (S), wherein the synthesis gas (S) is cooled and the air supply to the gasification is heated, of separating the synthesis gas (S) into a hydrogen stream and a carbon monoxide stream, of reacting the carbon monoxide with water steam to carbon monoxide and hydrogen, of separating also these secondary streams into a hydrogen stream and a carbon monoxide stream, and of bringing together the primary and secondary hydrogen stream into a product stream.
摘要:
Method and device for introducing pulverulent material (C) into a gasification reactor (2), wherein a process gas (P) supplied to a gasification reactor (2) is reduced to a synthesis gas (S) by the pulverulent material (C) and the pulverulent material (C) is introduced into the gasification reactor (2) via an inlet area, a negative pressure being generated in the inlet area for the pulverulent material (C) via a Laval nozzle (15) and the negative pressure being generated in that the process gas (P) passes through the Laval nozzle (15). The method is characterized in that the process gas (P) expands in a gasification space (5) in the gasification reactor (2).
