Разработана, изготовлена и исследована установка получения водорода из метана путем его пиролиза, включающая реактор и печь, предназначенную для его нагрева. Выполнен тепловой расчет установки с учетом теплоты, затрачиваемой на пиролиз, а также ее потерь через изоляцию и с уходящими газами при сжигании в печи метана, водорода, метано-водородной смеси, получаемой в процессе пиролиза. Выполнены расчеты по определению количества водорода, удельного расхода энергии на его получение, тепловой мощности и КПД установки при использовании в качестве топлива чистых метана и водорода, а также их смесей (70/30, 40/60). Натурные эксперименты на установке показали, что при сжигании смеси газов (60 % водорода и 40 % метана) при охлаждении уходящих газов (включающих углекислый газ и водяной пар) до температуры точки росы водяного пара получаем 0,55 кг дистиллированной воды на 1 м3 сжигаемой смеси. Анализ полученного пиролизного углерода показал       27 %-ное содержание наноматериалов (нановолокон). Для снижения температуры уходящих газов использованы калориферы, охлаждающим агентом в которых является водопроводная вода. После нагрева в калориферах она может быть использована для отопления помещений. Применение катализаторов позволило снизить температуру пиролиза от 1000 до 750 °С при 60 %-ном выходе водорода, что приводит к уменьшению расхода сжигаемой метано-водородной смеси на 40 % по сравнению с пиролизом метана при температуре 1000 °С с таким же количеством получаемого водорода. Применение метано-водородной смеси в качестве топлива газовой печи позволяет уменьшить выбросы углекислого газа в окружающую среду по сравнению с другими методами получения водорода ввиду того, что при его сгорании уходящие газы содержат лишь водяные пары.

A plant for producing hydrogen from methane by pyrolysis, including a reactor and a furnace designed to heat it, has been developed, manufactured and investigated. The thermal calculation of the installation has been performed taking into account the heat spent on pyrolysis, as well as its losses through insulation and with exhaust gases during combustion in the furnace of methane, hydrogen, and a methane-hydrogen mixture obtained during pyrolysis. Calculations have been performed to determine the amount of hydrogen, the specific energy consumption for its generation, the thermal power and efficiency of the installation when using pure methane and hydrogen, as well as their mixtures (70/30, 40/60), as a fuel. Field experiments at the plant have shown that when burning a mixture of gases (60 % hydrogen and 40 % methane) and cooling the exhaust gases (including carbon dioxide and water vapor) to the dew point temperature of water vapor, we obtain 0.55 kg of distilled water per 1 m3 of the burned mixture. The analysis of the obtained pyrolysis carbon showed a 27 % content of nanomaterials (nanofibers). To cool the exhaust gases, air heaters were employed, with tap water serving as the cooling agent. After being heated in the air heaters, the water can be utilized for space heating. The use of catalysts made it possible to reduce the pyrolysis temperature from 1000 °C to 750 °C while maintaining a 60% hydrogen yield, which results in a 40% reduction in the consumption of the methane–hydrogen combustion mixture compared to methane pyrolysis at 1000 °C producing the same amount of hydrogen. The application of a methane–hydrogen mixture as a fuel for a gas furnace makes it possible to reduce carbon dioxide emissions into the environment compared to other hydrogen production methods, since the combustion of hydrogen produces exhaust gases containing only water vapor.
