Product Details

Walter Taylor flow reactor

The Walter Taylor flow reactor is an efficient continuous flow reaction device designed based on the fluid dynamics characteristics of Taylor flow. It enhances mass transfer efficiency and reaction uniformity by forming a gas-liquid/liquid-liquid two-phase spiral layered flow in microchannels or tubular reactors, and is widely used in the fields of fine chemicals, energy conversion, and environmental governance.

Its core structure includes a tubular reaction channel (mostly made of stainless steel, glass, or fluoroplastic, with an inner diameter of usually 0.5-10 mm), a precision feeding system (including a plunger pump and gas/liquid flow meter), a temperature control module (jacket or microwave-assisted heating), and a gas-liquid separation unit. The inner wall of the channel can be modified according to requirements (such as catalytic coating or hydrophobic treatment) to adapt to different reaction systems.

During operation, two or more fluids (such as gas and liquid, immiscible liquids) are injected into the reaction channel in a specific ratio. Under the synergistic effect of flow velocity and channel geometry parameters, discrete liquid plugs and gas plugs (or liquid plugs) are alternately arranged. The liquid plugs move in a spiral motion along the pipe wall (Taylor flow characteristics), and strong internal circulation is generated at the interface. This flow mode increases the interfacial area by 10-100 times compared to traditional bubble reactors, and the mass transfer coefficient can reach 0.01-1 s ⁻¹, significantly shortening the reaction time.

In the application field, this reactor has significant advantages: in fine chemical synthesis, it can efficiently achieve gas-liquid reactions such as hydrogenation and oxidation, such as selective hydrogenation of phenylacetylene to produce styrene with a conversion rate of 98% and selectivity exceeding 99%; In terms of environmental governance, it is used for the absorption oxidation treatment of volatile organic compounds (VOCs) waste gas, with a removal rate of over 95% for pollutants such as toluene and acetone, and a treatment capacity of 0.1-5 m ³/h; In the energy field, it can be used for hydrogen source purification in fuel cells (such as CO selective oxidation), by strengthening the contact between the catalyst and reactants through Taylor flow, to maintain a CO removal rate of over 99.9%.

Its outstanding advantages are reflected in: mass transfer efficiency (5-20 times higher than traditional kettle reactors), low degree of backmixing (axial diffusion coefficient less than 0.01 cm ²/s), and strong controllability of reaction conditions (temperature fluctuations can be controlled within ± 0.5 ℃). Due to its small liquid holding capacity (usually only a few to tens of milliliters), it is particularly suitable for handling high-risk reactions (such as strongly exothermic and toxic chemical reactions), greatly improving safety. At the same time, modular series design can achieve flexible adjustment of production capacity, seamlessly connecting from laboratory milligram level synthesis to industrial ton level production. It is a key equipment in process enhancement technology that connects micro mass transfer and macro production.
