    • A method and apparatus for producing substitute natural gas are disclosed as including a plasma reactor (PR) which has arc discharge electrodes and a large number of minute arc passages (35) formed in solid carbon materials filled in the plasma reactor. Feed water is converted into steam in steam generating zone (34A) of the plasma reactor and the steam is fed through the minute arc passages in which steam reacts the solid carbon materials in the presence of arc plasmas to produce synthesis gas. The synthesis gas is supplied to a methanation reactor which converts the synthesis gas into substitute natural gas. The arc discharge electrodes may be supplied with controlled electric power such that a H 2 /CO ratio is maintained at a fixed value. The substitute natural gas may be cooled to separate condensed water, which is recycled to the plasma reactor for production of the steam therein.
    • 公开了一种用于制备替代天然气的方法和装置,包括具有电弧放电电极的等离子体反应器(PR)和在等离子体反应器中填充的固体碳材料中形成的大量微小电弧通道(35)。 给水在等离子体反应器的蒸汽发生区(34A)中转化为蒸汽,蒸汽通过微弧通道进料,蒸汽在电弧等离子体存在下使固体碳材料反应生成合成气。 将合成气供给到将合成气转化为替代天然气的甲烷化反应器。 可以向电弧放电电极提供受控电力,使得H2 / CO比保持在固定值。 替代天然气可以被冷却以分离冷凝水,其被再循环到等离子体反应器中以在其中生产蒸汽。

    • 1. Reactor apparatus for producing lean gas or generator gas from biomass or other low-temperature carbonisable waste products of all kinds, for example lubricating oils or the like, using a dual gasifier, comprising a primary gasifier with vertically adjustable level sieve and a discharging unit for the residues of combustion, the primary fuel and the pre-heated primary air being fed to the primary gasifier via the reactor bottom, and also comprising a downstream secondary gasifier in the style of a co-currently disposed coke generator with separate secondary air supply, characterised in that between the primary gasifier (2) and the secondary gasifier (20) there is provided a flue-current gas converter (14) into which passes a mixture of the secondary air for the secondary gasifier (20) and the low temperature carbonisable gas from the primary gasifier (2), along with the carbon particles exiting from the latter as a result of the centrifugal motion produced, the mixture and the carbon particles being channelled, with a high sojourn time under reducing conditions, by means of a radially symmetrical ring tuyere (19) to the secondary gasifier (20), and that in addition to the tuyeres (18) for supplying secondary air the flue-current gas converter (14) exhibits at least one foreign gas admission (30), said foreign gas admission (30) adapted to be connected, if required, to a bypass assembly to which at least a component current of the generator gas can be fed.
