A dispensing device includes: a primary tank which accommodates a liquid; primary-side pressure adjusting means for adjusting pressure in an interior of the primary tank; a plurality of branch flow paths connected to the primary tank; and a plurality of secondary tanks which are provided corresponding to the plurality of branch flow paths, respectively, and each of which is connected to a corresponding branch flow path.

Fluid transport approaches are described that operate without the need for precise displacement of an actuator and with little or no sensing in the flow path. In certain implementations, a gas phase in a fluid reservoir is compressed by a pressure source such that releasing the pressure, such as by opening a valve to an intermediary conduit, displaces fluid to the intermediary chamber. Closing that fluid path and opening a different fluid path to a chamber at ambient temperature causes the fluid to be displaced to the chamber.

Disclosed microscale reactors comprise lamina for carrying out multi-phase reactions for making desired chemical products, such as biohydrogenated diesel (BHD). Microreactor embodiments include a bottom clamp plate, a top clamp plate, and at least one catalyst plate positioned between and operatively associated with the bottom clamp plate and the top clamp plate. Catalyst plates include a catalyst associated for catalyzing the production of product from feedstock. To address the problems encountered when using microchannel reactors, the microscale-based reactors may include a mixer plate assembly and/or at least one catalyst lamina comprising an array of microscale posts. Disclosed microreactor systems for producing BHD include a feedstock source, a hydrogen source and an inert gas source each fluidly coupled to respective microreactor inlets. Certain method embodiments include operating a microreactor or a microreactor system to produce BHD from a suitable feedstock selected from animal fats, vegetable oils, or combinations thereof.

A flow reactor system and methods having tubing useful as polymerization chamber. The flow reactor has at least one inlet and at least one mixing chamber, and an outlet. The method includes providing two phases, an aqueous phase and a non-aqueous phase and forming an emulsion for introduction into the flow reactor.

A device for hydrogen production with waste aluminum includes a treatment apparatus for waste aluminum and a reaction tank. The apparatus includes a first crusher, a pickling tank, and a second crusher. The first crusher is for preliminarily crushing waste aluminum to obtain first aluminum chips. The pickling tank is for receiving and pickling the first aluminum chips crushed by the first crusher. The second crusher is for receiving and fine crushing the first aluminum chips to obtain second aluminum chips. The second aluminum chips are received by the reaction tank and then hydrolyzed with an alkaline solution in the reaction tank to produce hydrogen. Since waste aluminum is used as the raw material of hydrogen production, and a specific device is used for waste aluminum treatment, so the effects of recovering waste metal, reducing environmental damage, and saving costs can be achieved at the same time.

A reactor system for high throughput applications includes a plurality of reactor assemblies, each reactor assembly including: a fluid source, which fluid source is adapted to provide a pressurized fluid to the flow-through reactors, a flow splitter which flow splitter includes a planar microfluidic chip, which microfluidic chip has a chip inlet channel and a plurality of chip outlet channels, which microfluidic chip further includes a plurality of flow restrictor channels, where each flow restrictor channel extends from said chip inlet channel to an associated chip outlet channel, where the chip inlet channel and the chip outlet channels each have a diameter, where the diameter of the chip inlet channel is the same or less than the length of said chip inlet channel and where the diameter of each chip outlet channel is the same or less than the length of said chip outlet channel.

Provided is a microreactor which can be produced at a lower cost. The microreactor has a transfer means for transferring a liquid raw material using the pressure of a gas. The microreactor has a raw material tank for storing the liquid raw material. The transfer means for transferring a liquid raw material can transfer the liquid raw material stored in the raw material tank using the pressure of a gas in the raw material tank. A pipe which connects the raw material tank and the next device is preferably provided with a small diameter portion.

A hydrogenation method for preparing HBPA includes placing a BPA reaction liquid into a hydrogenation vessel with a hollow-shaft stirrer installed inside; starting the hollow-shaft stirrer to stir the BPA reaction liquid and simultaneously allowing hydrogen gas evenly distributed over and contact well with the BPA reaction liquid; in the presence of a single-metallic Ru/Al2O3 hydrogenation catalyst to proceed with a catalytic hydrogenation at low temperature and low pressure to produce HBPA, the HBPA has a yield of 99.7% or more, and particularly having a trans/trans isomer ratio above 63%.
