Electrode Fixed Bed

Electrode Fixed Bed

The electrode-fixed bed is a technological device that combines the effects of an electric field with a fixed-bed structure, and it finds important applications in a variety of fields—including environmental engineering, bioengineering, and chemical production. Like traditional fixed beds, it consists of a vessel filled with solid particles. These solid particles typically exhibit a certain particle size distribution and pore structure, offering a large specific surface area that provides a suitable environment for various physical and chemical processes. For example, in catalytic reactions, the solid particles may serve as supports loaded with catalysts; in adsorption processes, the particles may be adsorbents such as activated carbon.

Microbubble Fixed Bed

Microbubble Fixed Bed

Microbubble process intensification in fixed beds is a technological approach with significant applications in fields such as chemical engineering and environmental science. By employing specialized equipment or methods, gas is dispersed into tiny bubbles, typically on the micrometer scale. These microbubbles possess a large specific surface area, providing an increased gas–liquid interfacial area. This dramatically enhances gas–liquid mass transfer efficiency; for processes that are mass-transfer–limited—such as gas absorption and liquid-phase oxidation—it can significantly accelerate reaction rates and improve production efficiency. Moreover, due to the enhanced mass transfer efficiency, the volume of fixed bed required for processing the same amount of material is relatively small, resulting in a compact footprint for the equipment and facilitating plant layout and construction.

Fully Automatic Fischer–Tropsch Synthesis Apparatus

Fully Automatic Fischer–Tropsch Synthesis Apparatus

The fully automatic fixed-bed reactor operates at a temperature range of RT–1000℃ for gas‑phase reactions with 6 gases and 2 liquids, employing a process control system (sequence control). It is constructed from quartz and 316L 625 reactor materials, with the entire system undergoing passivation treatment. Three-stage condensation ensures automatic discharge of condensates (wax, water, gasoline) without pressure fluctuations, while pressure is automatically controlled. The system features robust safety protection mechanisms at the hardware level, including safety relief valves, to ensure safe operation even in the event of emergencies such as power outages or gas supply interruptions.

Mobile Hydrogenation Reactor

Mobile Hydrogenation Reactor

The fixed-bed catalyst evaluation unit is primarily used for research on catalytic processes. The unit is equipped with a reactor made of 316L material, which features an oil-bath jacket. The unit comprises three main sections: the feed unit, the reaction unit, and the cooling & separation unit. All major instruments and piping valves in the unit are sourced from well‑known, high‑quality brands. Non‑standard components are fabricated from corrosion‑resistant materials. The unit employs a PLC control system and is outfitted with multi‑tiered, critical safety protection systems to ensure the safety of both equipment and operating personnel. The design objective is to establish a high‑quality, high‑performance test facility tailored for continuous reactions under high temperature and high pressure. The overall performance of the unit must feature a high degree of automation, excellent data accuracy and repeatability, as well as robust safety and reliable, long‑term stable operation.

Flow Hydrogenation Reactor

Flow Hydrogenation Reactor

Hydrogenation is one of the more important reactions in chemical synthesis; however, the inherent hazards associated with hydrogen have limited its widespread application. In a continuous-flow hydrogenator, the substrate flows continuously and is mixed with hydrogen generated via in-situ electrolysis before entering the reaction chamber. Thanks to the advancements in microfluidic technology, the efficiency of three-phase mixing is significantly enhanced. The hydrogen–substrate mixture can be rapidly and uniformly heated to 150°C and 100 bar; under these conditions, most reactions achieve extremely high conversion rates in just a few minutes. Within the catalytic column, the hydrogen–substrate mixture comes into effective contact with the catalyst surface, undergoing rapid reactions under high temperature and high pressure before being collected after passing through a filter. Within just a few minutes, it is possible to reduce 10 mg to 100 g of reactants with exceptionally high conversion yields. The system is operated via a touch-screen display, offering simple operation, a high degree of intelligence, and the ability to modify reactions on‑line.
