Abstract: A gas processing system includes an input gas supply, an output gas storage container and/or an inlet to a secondary reactor, and a solar-thermal reactor. The solar-thermal reactor uses a solar collector to focus sunlight onto a reactor, the reactor having a housing that encloses a reaction chamber, a catalyst arranged therein, an inlet for receiving the input gas and an outlet for expelling the output gas. Sunlight is focused by the solar collector to heat the reactor and thereby chemically convert the input gas from the gas supply into the output gas that can be stored in the output gas container or directed towards the secondary reactor.

Abstract: The present invention is directed to both stoichiometric and sub-stoichiometric high entropy aluminate spinels as a novel high entropy oxide (HEO) crystal phase. Previously reported HEOs are overwhelmingly stoichiometric structures containing a single cationic site and are stabilized solely by intermixing increasing numbers of cations. According to an aspect of the invention, sub-stoichiometric spinels, containing various mixtures of divalent metal cations and cationic vacancies in nominally equimolar concentration, provide entropic stabilization similarly to cations in stoichiometric spinels. The chromatic, structural, and chemical properties of these complex spinels are highly tunable via incorporation of cationic vacancies and multiple divalent metals, enabling their application as unique pigments, catalysts, and thermal coatings.

Abstract: Steam cracking of ethane, a non-catalytic thermochemical process, remains the dominant means of ethylene production. The severe reaction conditions and energy expenditure involved in this process incentivize the search for alternative reaction pathways and reactor designs which maximize ethylene yield while minimizing cost and energy input. According to the present invention, ethylene yields as high as 68% were obtained with a quartz open tube reactor without the use of a catalyst or a cofed stream of oxidizing agents. The open tube reactor design promotes simplicity, low cost, and negligible coke formation. Reactor designs can be optimized to improve the conversion of ethane to ethylene via non-oxidative dehydrogenation, an approach which shows promise for decentralized production of ethylene from natural gas deposits.

Abstract: High surface area, high entropy oxides comprising multiple metal cations in a single-phase fluorite lattice material enables intrinsic catalytic activity without platinum group metals, tunable oxygen storage capacity, and thermal stability. These properties can be obtained through a facile sol-gel synthesis to provide a low-temperature route for production of phase-pure multi-cationic oxides. The resulting materials achieved significantly higher surface area and catalytic performance, taking advantage of all the properties endowed by the various cations in the composition.
