    • @ A process wherein coal is reacted with a hot gas stream to produce acetylene. The process comprises the sequential steps of reacting a fuel, oxygen and steam under controlled conditions of temperature to produce a hot gas stream principally comprising hydrogen, carbon monoxide and steam along with minor amounts of carbon dioxide, and essentially free of 0, OH and O 2 . The hot gas stream is accelerated to a high velocity and impinged upon a stream of particulate bituminous or subbituminous coal and thereafter the mixture of hot gas and coal is decelerated to a velocity of from about 150 to 300 feet per second. The amounts of the streams of particulate coal and hot gas are controlled to produce in the reaction zone a pressure in the range of from about 10 to 100 psia and a temperature of from about 1800° to 3000°F. The mixture of coal and hot gas is maintained at that pressure and temperature for a time of from about 2 to 30 milliseconds to produce a product stream including char and acetylene. The temperature of the product stream is then reduced to less than about 900°F in a time of less than about 2 milliseconds to substantially arrest any further reactions and the acetylene is recovered therefrom. The char is recovered and used as at least a part of the fuel used to produce hot gas.

    • The plant for gasification of coal into methane or synthetic gas comprises a hydrogenation gasifier (2), a vapour gasifier (4), a convertion (17) an fractionation (9) device. The coal to be gasified is first introduced into the hydrogenation gasifier, and then into the vapour gasifier wherein an almost complete gasification takes place. The crude gas coming from one gasifier is used to heat the other gasifier. The thermal energy required for the process comes from a nuclear reactor and is partly either in the form of electrical energy or in the form of vapour. The terminal part of the vapour gasifier has to be heated electrically so as to obtain the high temperature required for the process and yet this high temperature should not be allow for the reactor (23). Further, with such a process, the reactor may be separated and uncoupled from the gasification plant. When such a plant is used only for the production of synthesis gas, the upper part of the furnace for the separation of methane necessary in this case, with all the advantages mentions above, is also heated electrically.
    • 用于将煤气化成甲烷或合成气体的设备包括氢化气化器(2),蒸气气化器(4),转化器(17)和分馏(9)装置。 待气化的煤首先被引入加氢气化器,然后进入其中几乎完全气化发生的蒸气气化器。 来自一台气化炉的粗煤气用于加热另一台气化炉。 该过程所需的热能来自核反应堆,部分为电能形式或蒸汽形式。 蒸气气化器的末端部分必须被电加热,以便获得该过程所需的高温,而反应器(23)不应允许该高温。 此外,通过这种方法,反应器可以与气化装置分离和分离。 当这种设备仅用于生产合成气时,在这种情况下所需的用于分离甲烷的炉的上部具有以上所述的所有优点,也被电加热。
