A series of three chemical reactions, including a combination of endothermic and exothermic reactions, is used to generate, store, and supply on-demand heat from renewable energy sources for use in a variety of processes. Products from one reaction are used in the next reaction, and the series of three reactions is carried out once or more than once, optionally as a closed loop process.

An integrated process is provided for producing benzene, toluene, and/or xylene and hydrogen from shale gas under the feeding of carbon dioxide. The integrated process for producing an aromatic compound and hydrogen can efficiently and continuously produce high value-added aromatic compounds and hydrogen without the need to separate methane from shale gas through cryogenic distillation.

The presently disclosed embodiments relate to the utilization of coal-derived fine mineral matter in chemical recycling of plastics or of solid mixed plastic waste. The instantly disclosed mineral based catalyst benefits the processes of catalytic cracking, gasification and steam reforming to maximize carbon utilization and production of plastics of original quality from recycled or renewable feedstocks while reducing the plastic pollution in the environment. The catalyst can be based on inorganic fine mineral matter, a natural ancient mineral mixture found in coal deposits and containing a plurality of transition metals, such as iron, copper, and manganese, as well as calcium, barium, magnesium, potassium, sodium, which can act as co-catalysts. Addition of the catalyst can convert plastic to syngas at a faction of the energy of conventional technologies.

A method and system for an enhanced reforming process employing a pressure swing absorber. An off-gas from the pressure swing absorber is divided with a first portion sent back into a reforming reactor and a second portion sent to a heat generator for the reforming process. The first off-gas portion from the pressure swing absorber can be pressurized by a compressor and reintroduced into a fluidized bed reactor.

The present invention is directed at the conversion of ammonium nitrate and related compounds upon reaction with methane into compounds such as ethyl acetate, ammonia, nitrogen and hydrogen. The reaction may proceed within a fluid-solid type reactor. The reaction may be facilitated in the presence of inert or catalytic solids.

Embodiments of the invention relate to systems and methods for cracking hydrocarbons into hydrogen gas and carbon using heating of a fluidized bed. The systems and methods utilize electrically conductive carbon or graphite particles as a fluidized bed material for heating hydrocarbon feedstock to at least a pyrolysis temperature. The electrically conductive carbon, graphite, or other particles may be heated by electrically powered sources that include induction heating, microwave heating, millimeter wave heating, joule heating and/or plasma heating. Combustion heating may also be employed in varying amounts with varying combinations of electrically powered heating sources.
