Silicon carbide microchannel reactorchip architecture

Silicon carbide microchannel reactorChip cross-sectional structure

Material advantages:

1. The reactor chip is made of pressureless sintered silicon carbide material, with a purity of over 99.5%, and has strong corrosion resistance. It can handle strong corrosive substances such as hydrogen peroxide, KOH, etc; The thermal conductivity of the material is about 130W/mK, which greatly improves the heat transfer conditions during the reaction process and accelerates the reaction rate;

2. The company has complete production and processing conditions for silicon carbide, which can achieve precision machining of complex and irregular silicon carbide products, ensuring product quality and delivery speed;

3. Having years of experience in the production and processing of silicon carbide products, mastering the core technologies of silicon carbide reactor production, covering design, materials, processes, process optimization, assembly, as well as post commissioning and maintenance;

Design advantages:

1. The reaction unit is a multi-layer silicon carbide plate structure, which includes multiple layers of reaction channels and multiple layers of heat exchange channels. It is fused into a whole using bonding technology, greatly improving the pressure resistance and heat exchange capacity;

2. The external of the reaction unit is wrapped with carbon fiber insulation layer and stainless steel shell, which improves the safety and temperature control accuracy of use;

3. The internal reaction layer and heat exchange layer of the reactor chip are integrated inside the silicon carbide, using an integrated bonding packaging structure, with a heat transfer capacity several times that of products with external heat exchange plate structures;

4. The reaction channel is a three-dimensional structure that can achieve simultaneous mixing of reactants in both planar and vertical directions in turbulent and vortex forms, ensuring ideal mixing effects at lower pressure drops;

5. The inlet and outlet pipelines of the reactor design can be flexibly selected, including PTFE, 316L, alloy pipes, etc; Each reactor module includes multiple inlets, and the secondary inlet can be flexibly adjusted and used;

6. For models that require external connecting pipes, the connecting pipes are PFA hard pipes, installed in a pressure resistant, temperature resistant, and corrosion-resistant manner, with quick disassembly function and support for repeated disassembly (no deformation or leakage after more than 50 times); The pressure resistance of the connecting pipe itself is over 50 kilograms;

7. The heat exchange medium of the unit can be distributed in parallel to each module and can be adjusted according to demand (each reaction module can be adjusted separately): the whole machine is equipped with a stainless steel frame and an overall protective shell;

Performance advantages:

1. The liquid holding capacity of the chip covers various models ranging from 1ml to 400ml, and users can choose according to their needs. The annual throughput of a single industrial reactor can reach up to 5000 cubic meters;

2. Operating temperature of conventional reactor modelsThe lowestUp to -45 ℃ (special customized models can reach -80 ℃),higherUp to+275 ℃ (special customized models can reach+400 ℃);

3. Conventional type reactorlargerThe pressure resistance can reach 6Mpa (special models can be customized)larger10Mpa);

4. Covering various working conditions from laboratory low flux to large-scale industrial applications in factories, with a wide range of applications and complete functions, it can be flexibly customized according to actual working conditions;
