The present invention relates to a device for the photocatalytic reduction of a substance with a structured reaction plate and/or a structured housing, wherein the reaction plate has, at least in some regions, a surface which contains a material with negative electron affinity and which can be electronically excited with radiation having a wavelength of ≥180 nm.

Disclosed are a general-purpose fluorescent fluid photochemical microreactor and a manufacturing method therefor by means of 3D printing, belonging to the technical field of photochemical reactor research. By using a transparent photosensitive resin and the strong space building capacity of 3D printing, a photochemical microreactor having both a light-collecting channel and a reaction channel is prepared. By means of introducing a light-collecting substance in a fluid form into a light channel, not only can play the role of light collection and wavelength conversion, which solves the difficulty of traditional photochemical reactors of light source matching, but also the light-collecting substance can be flexibly changed so as to meet the requirements of different photochemical reactions in the reaction channel, which greatly expands the application range of the reactor.

A reactor for steam-methane reforming is adapted to be received in a tube on a focal axis of a parabolic trough.

The reactor assemblies can also provide where the channels of either one or both of the first of the set of fluid channels are non-linear. Other implementations provide for at least one of the first set of fluid channels being in thermal contact with a plurality of other channels of the second set of fluid channels. Reactor assemblies are also provided that can include a first set of fluid channels defining at least one non-linear channel having a positive function, and a second set of fluid channels defining at least another non-linear channel having a negative function in relation to the positive function of the one non-linear channel of the first set of fluid channels. Processes for distributing energy across a reactor are provided. The processes can include transporting reactants via a first set of fluid channels to a second set of fluid channels, and thermally engaging at least one of the first set of fluid channels with at least two of the second set of fluid channels.

A micro-fluidic reactor may comprise a photosensitive glass substrate with a plurality of features produced by etching. The features may include micro-channels, micro-lenses, and slots for receiving optical fibers. During operation of the micro-fluidic reactor, the optical fibers may transmit optical signals for measuring characteristics of fluid reagents and reactions taking place. The micro-lenses may focus optical signals from the optical fibers to create an approximately collimated optical path for the optical signals, reducing optical spread and enhancing fiber-to-fiber optical power coupling.

The present invention provides control methods, control systems, and control software for microfluidic devices that operate by moving discrete micro-droplets through a sequence of determined configurations. Such microfluidic devices are preferably constructed in a hierarchical and modular fashion which is reflected in the preferred structure of the provided methods and systems. In particular, the methods are structured into low-level device component control functions, middle-level actuator control functions, and high-level micro-droplet control functions. Advantageously, a microfluidic device may thereby be instructed to perform an intended reaction or analysis by invoking micro-droplet control function that perform intuitive tasks like measuring, mixing, heating, and so forth. The systems are preferably programmable and capable of accommodating microfluidic devices controlled by low voltages and constructed in standardized configurations. Advantageously, a single control system can thereby control numerous different reactions in numerous different microfluidic devices simply by loading different easily understood micro-droplet programs.
