Abstract: Provided are methods for preparing hydrogen and solid carbon. Illustrative methods comprise providing a feedstock comprising gaseous hydrocarbons to a microwave-inert reaction vessel and/or a radio wave-inert reaction vessel. The reaction vessel has solid carbon, about 0% water and about 0% molecular oxygen inside the reaction vessel and the carbon inside the reaction vessel is operable to heat the feedstock comprising gaseous hydrocarbons. The carbon is then exposed to microwaves and/or radio waves until the solid carbon is at a temperature of at least 1200 Kelvin, thereby forming hydrogen and solid carbon. Once formed, the hydrogen and solid carbon are separated.

Abstract: Ceramic monolith compositions are provided with improved stability under reaction conditions involving elevated temperatures. Such monoliths can be used, for example, in reverse flow reactors under high temperature reforming conditions, where the interior components of the reaction zone can be exposed to average temperatures of 1000° C. or higher while also being exposed to rapid oscillations in temperature of 100° C. or more in the presence of alternating oxidizing and reducing chemistries. The ceramic monolith compositions can be composed of materials that have improved ability to withstand conditions in severe reaction environments. Additionally or alternately, the ceramic monolith compositions can have structural features that reduce or minimize the tendency for the monolith to suffer structural failure under the conditions in severe reaction environments.

Abstract: A heat and hydrogen generation device comprising a burner combustion chamber (3), a burner (7) for feeding fuel and air into the burner combustion chamber (3), and a reformer catalyst (4). The target value of the O2/C molar ratio of air and fuel which are made to react in the burner combustion chamber (3) is preset as the target O2/C molar ratio. The actual O2/C molar ratio at the time of warm-up operation is estimated from the rate of temperature rise of the reformer catalyst (4) etc., when performing warm-up operation. When the estimated actual O2/C molar ratio deviates from the target O2/C molar ratio at the time of warm-up operation, the ratio of feed between the amount of feed of air for burner combustion and the amount of feed of fuel for burner combustion is corrected, in a direction making the estimated actual O2/C molar ratio approach the target O2/C molar ratio at the time of warm-up operation.

Abstract: In an ammonia or hydrogen plant comprising a desulfurisation section, a reforming section and a shift section, where the shift section comprises a low temperature shift converter and a medium temperature shift converter, a vent line is arranged downstream from the low temperature shift converter and the medium temperature shift converter in order to allow the shift converters to be re-heated with process gas at a low pressure (typically 3-7 bar). This way condensation of water vapour in the process gas is avoided. By applying this vent line it becomes possible to save significant time, more specifically 8-24 hours, for restarting the production after temporary shut-down thereof, because a heat-up of the LTS/MTS converter in circulating nitrogen is avoided.
