Disclosed apparatuses, systems, and materials relate to the disassociation of feedstock species (such as those in gaseous form) into constituent components, and may include an energy generator configured to provide a microwave energy. A first chamber defines a first volume and is configured to guide the microwave energy along the first chamber as a sinusoidal wave having an energy maxima at a point along the first chamber. A second chamber contains a plasma plume and is positioned substantially proximal to the first chamber, and is configured to enable propagation of the microwave energy through the first chamber and the second chamber such that the microwave energy demonstrates, at a radial center of the second chamber, a coaxial energy maxima configured to ignite the plasma plume contained in the second chamber. Carbon-containing materials may be formed by controlling flow parameters of the feedstock species into the first or second chamber.

The present disclosure relates to the field of reactor technologies and in particular to a solid-liquid phase reactor for preparing a powder product, which includes a vessel shell, a material-restricting partition net, a solid reactant charge opening, and a reaction solution make-up opening. The material-restricting partition net is disposed in a cavity of the vessel shell and connected to the vessel shell.

A frame of the semi-closed material-restricting zone is rigid. The solid reactant charge opening is in communication with the facing-up opening of the semi-closed material-restricting zone, and the reaction solution make-up opening is in communication with an internal space of the semi-closed material-restricting zone.

This invention relates to processes and systems for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons and/or aromatics, for example converting acyclic C.sub.5 hydrocarbons to cyclopentadiene in a reactor system. The process includes heating an electrically-conductive reaction zone by applying an electrical current to the first electrically-conductive reaction zone; and contacting a feedstock comprising acyclic hydrocarbons with a catalyst material in the electrically-conductive reaction zone under reaction conditions to convert at least a portion of the acyclic hydrocarbons to an effluent comprising alkenes, cyclic hydrocarbons, and/or aromatics.

A reactor suitable for a reaction containing an exothermic reaction is provided. The reactor includes the following components. A reaction channel has an inlet and an outlet, and has a front-end reaction zone, middle-end reaction zones, and a back-end reaction zone from the inlet to the outlet. A front-end catalyst support and a front-end catalyst are located in the front-end reaction zone, a middle-end catalyst support and a middle-end catalyst are respectively located in the middle-end reaction zones, and a back-end catalyst support and a back-end catalyst are located in the back-end reaction zone. The concentration of the front-end catalyst is less than the concentration of the back-end catalyst, and the concentration of the middle-end catalyst is decided via a computer simulation of reaction parameters. The reaction parameters include size and geometric shape of the reaction channel.

Some of the present reactors and systems include a reactor body having a substantially-planar bottom and one or more sidewalls extending from the bottom to define a recess, the reactor body defining inlet(s) and outlet(s) for liquid and gas, and a lid configured to be coupled to the reactor body to cover the recess such that the interface between the reactor body and the lid is substantially sealed, where at least one of the reactor body and the lid is configured to transmit incident ultraviolet light into the recess, and where the reactor body is configured to receive a photocatalyst in the recess such that at least a portion of liquid delivered to the recess through the liquid inlet(s) can react with the photocatalyst in the presence of the ultraviolet light to generate gas. Some reactors and systems include liquid and gas circulation systems having pumps and conduits.

A chemical manufacturing system is used in chemical reactions involving a gas, gases or liquid which is turned into a gas, reacting with a solid or liquid, inside a closed reactor system. The chemical manufacturing system is designed to produce highly reactive materials on an industrial scale in a controllable fashion. The modular design and shape of the reactor system and the controls of the system account for the differentiation and improvements over conventional reactor systems.

An electromagnetic resonance apparatus for molecular, atomic, and chemical modification of water is provided. The apparatus includes a water container, a resonance induction cell tower, an electronic control unit, a 12-volt power source, a DC to AC power inverter, and a pressure vessel for storing produced hydrogen gas. An electronic control unit is used to provide vibrational energy to the cell tower to facilitate water decomposition.

The present invention discloses a fuel supply for a fuel cell, the fuel cell including a liquid storage area that includes a liquid reactant, a reaction area that includes a solid reactant, wherein the liquid reactant is pumped into the reaction area such that the liquid reactant reacts with the solid reactant to produce reaction components, a product collection area that receives the reaction components, a barrier, and a container with an interior volume that substantially encloses the reaction area, liquid storage area, product collection area. The barrier separates and defines several of the aforementioned areas, and moves to simultaneously increase the product collector area and decrease the liquid storage area as the liquid reactant is pumped from the liquid storage area and the reaction components are transferred into the product collection area.
