用于在间接加热的气化过程中制备焦炭的方法和装置
Abstract:
本发明涉及一种用于在间接加热的气化工艺中制备焦炭(PC)的方法，其中向气化反应器(1)供应煤颗粒，将气化工艺中供应的工艺气体(P)在气化反应器(1)中还原为合成气(S)，借此将合成气(S)从气化反应器(1)移除。本发明还涉及用于实施所述方法的装置。根据本发明的方法的区别之处在于，在气化进行的同时，煤的焦化也在气化反应器(1)内部布置的内反应器(4)中进行，内反应器(4)被间接加热，在焦化过程中焦炭(PC)和可燃气体在内反应器(4)中产出，而可燃气体则被用于气化反应器(1)的气化过程中的间接加热。
Abstract(English):

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).
