Abstract: The invention relates to a process for producing hydrogen, having a steam methane reforming step for producing synthesis gas, in which heat for the endothermic reaction is at least partially provided by converting electrical energy into heat. The synthesis gas is subject to a water-gas shift step and the shift product is subject to a chemical scrubbing step, to afford a carbon dioxide product stream and a hydrogen raw product stream. The hydrogen raw product stream is further purified by means of a hydrogen production step, which affords pure hydrogen and an off-gas stream. The off-gas stream, rich in carbon monoxide and methane, is recycled to the hydrocarbon containing feedstock stream, so that a combined stream of hydrocarbon containing feedstock, off-gas and steam is supplied to the steam methane reforming (SMR) step.

Abstract: A process for making recycle content ammonia by reacting hydrogen with nitrogen. At least a portion of the hydrogen is obtained directly or indirectly by molecular reforming a mixed plastic waste or pyrolysis product feedstock. The molecular reforming can be a steam reforming process or a partial oxidation process, such as a partial oxidation gasifier, to generate the syngas used as a source of hydrogen. The recycle content associated with the ammonia can be obtained from the mixed plastic waste, the recycle content in the pyrolysis product, such as pyoil or pygas, or the recycle content in the syngas or the purified hydrogen stream from the syngas.

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.
