Abstract: Exemplary reactor systems may include multiple reactors in fluid communication. Oxygen carrier particles comprising a support material and metal oxide can be provided to a first reactor along with flue gas comprising carbon dioxide (CO2). An output of the first reactor is free or substantially free of carbon dioxide (CO2). The oxygen carrier particles can then be provided to one or more reactors in the system along with a hydrocarbon stream and, in some instances, an oxidizing stream. Outlets from these one or more reactors may include hydrogen gas (H2), carbon monoxide (CO), and/or other species, depending upon the content of the hydrocarbon streams and the oxidizing streams.

A reactor may comprise a feedstock inlet in fluid communication with a carbonaceous feedstock source, a product stream outlet, and oxygen carrier particles. Exemplary reactors may be operated by providing a carbonaceous feedstock to an inlet of the reactor, providing oxygen carrier particles within the reactor, and collecting a product stream from an outlet of the reactor.

Abstract: Systems and methods generally involve processing a gaseous reducing agent and a gaseous reforming agent to produce syngas in the presence of a stable-phase change metal-oxide based oxygen carrier. During operation, an oxygen content is measured for a reactor input stream and a reactor output stream. A percent oxygen depletion of the metal oxide is determined using an initial oxygen content of the metal oxide, the oxygen content of the input stream, and the oxygen content of the output stream. Based on the percent oxygen depletion, a mole ratio of reducing gas to oxidant in the input stream may be adjusted accordingly.

Abstract: A link binding chain is disclosed that enables multiple hops of link bindings to be cascaded to form a chain of link bindings. The binding chain can be leveraged when a one-hop link binding is infeasible or fails to be established. Dynamic binding method switching is disclosed for updating the binding method after a link binding has been established such that the link binding may be selected for a more proper or efficient link binding method to adapt to the changing environment. Methods for broker assisted link binding are disclosed to facilitate link binding functionalities between a source resource and a destination resource that are connected through a binding broker.

Abstract: A registrar entity, such as a service layer gateway, obtains the service capabilities requirements or preferences of a new registree entity, such as an application, and only accepts a registration of the registree if the registrar has sufficient remaining service capacities to meet the service capabilities requirements or preferences of the registree entity while ensuring that the provision of support to existing registree entities is not impacted. If the registrar lacks the capabilities to satisfy the requirements or preferences, it may contact a server to identify another registrar which has the capabilities. Updates to requirements or preference may originate at any node, e.g., at a user equipment device or a service.
