Abstract

Изобретение относится к химии и химической технологии, а именно к способам получения гидридов металлов. В способе получения гидридов металлов, включающем использование водорода для образования гидридов металлов, уголь нагревают до температуры 700°C нагретым водяным газом в тепловом реакторе, полученным газификацией угля, очищают от всех летучих веществ и осуществляют паровую газификацию углеродистого материала при соотношении C:H2O=1:1, образующийся при этом водяной газ предварительно используют для нагрева угля и получения углеродистого материала, охлаждают до температуры 300°C водой с образованием водяного пара, который используют для паровой конверсии углеродистых веществ, охлаждённый водяной газ смешивают с водяным паром в соотношении CO:H2O=1:1 и подают в реактор конверсии оксида углерода, где осуществляют каталитическую конверсию оксида углерода при температуре 300-340°C, образующийся конвертированный газ охлаждают до 18-20°C и выделяют из его состава двуокись углерода абсорбцией растворами щелочей. Оставшийся газ, состоящий из водорода с парами воды, охлаждают в аммиачном холодильнике, выделенный от конденсировавшихся паров воды чистый водород используют в качестве газовой среды в плазмотроне для осуществления плазмохимических реакций образования гидридов металлов из их неорганических солей.The invention relates to chemistry and chemical technology, and in particular to methods for producing metal hydrides. In the method for producing metal hydrides, including the use of hydrogen for the formation of metal hydrides, coal is heated to a temperature of 700 ° C with heated water gas in a thermal reactor obtained by coal gasification, purified from all volatiles and steam gasification of carbonaceous material is carried out at a ratio of C: H2O = 1 : 1, the resulting water gas is preliminarily used to heat coal and obtain a carbonaceous material, cooled to a temperature of 300 ° C with water to form water vapor, which is used for steam reforming of carbonaceous substances, the cooled water gas is mixed with water vapor in the CO: H2O ratio = 1: 1 and fed to the carbon monoxide conversion reactor, where the catalytic conversion of carbon monoxide is carried out at a temperature of 300-340 ° C, the resulting converted gas is cooled to 18-20 ° C and carbon dioxide is separated from its composition by absorption with alkali solutions. The remaining gas, consisting of hydrogen with water vapor, is cooled in an ammonia cooler, pure hydrogen separated from the condensed water vapor is used as a gaseous medium in the plasmatron to carry out plasma-chemical reactions of the formation of metal hydrides from their inorganic salts.
