A hydrogen based mixing system for the fabrication of nanoparticles allowing for selection of specified particle size, narrow particle size distribution and core shell nanoparticle encapsulation. A further description of a Dense Energy UltraCapacitor that utilizes the core shell nanoparticles to create an energy storage device.

Systems/methods for continuous operation of fixed bed reactors using gaseous fuels for power generation through integration with a combined cycle power plant are provided. The fixed bed reactors are assumed to operate in a semi-batch mode composed of reactor modules integrated into module trains that comprise the chemical-looping combustion island of the power plant. The scheduling of each reactor train is cast as an optimization problem that maximizes thermodynamic efficiency subject to constraints imposed to each reactor and the entire island. When the chemical-looping reactors are arranged cyclically, each feeding to or being fed from another reactor, in an operating scheme that mimics simulated moving bed reactors, the thermodynamic efficiency of the reactor island can be improved. Allowing the reversal of module order in the cyclically arranged reactor modules further improves the overall thermodynamic efficiency, while satisfying constraints imposed for carbon capture, fuel conversion, power plant safety and oxygen carrier stability.

A biomethanol production system and method is provided. The system comprises (a) a feed stream comprising methane, water, and carbon dioxide; (b) a reformer reactor capable of reacting the feed stream to form a syngas mixture comprising hydrogen, carbon monoxide, and carbon dioxide; (c) a methanol reactor capable of reacting the syngas mixture to form biomethanol product; (d) a wash column comprising the syngas mixture and the biomethanol product, wherein the biomethanol product is capable of absorbing carbon dioxide from the syngas mixture; and (e) a flash column comprising a vent capable of venting the absorbed carbon dioxide. A method for removing carbon dioxide from a biomethanol production system is also provided.

An apparatus for a rotating packed bed reactor (RPB) that may be used to increase the mass-transfer rate between materials, such as a gas and a liquid, through the RPB. The RPB includes a housing, a motor, and a rotor disposed within the housing and operatively connected with the motor. The rotor includes a permeable packing configured to facilitate contact between a liquid and a gas passing through the permeable packing. The rotor includes a heat sink in contact with the permeable packing and configured to transfer heat away from the permeable packing. The heat sink includes a heat rate transfer gradient in a radially inward direction between an outer circumferential surface of the permeable packing and a central axis of the permeable packing.

A continuous flow process and system for depolymerizing plastic. A heterogeneous mixture of solid plastic particles, a solvent, and a catalyst are pumped continuously through a heating zone at a flow rate resulting in a particle speed sufficient to keep the plastic particles in suspension. The heterogeneous mixture is heated in the heating zone and maintained in a hold zone to complete depolymerization of the mixture into a homogeneous solution containing a liquefied reaction product. The homogeneous solution is cooled to solidify and precipitate a solid reaction product. The solid reaction product is separated from the solvent to be recycled. Contaminants are removed from the solvent, and the solvent is recirculated for use as a constituent of the heterogeneous mixture.
