1000L High-Pressure Reactor

　　The reactor vessel materials can include carbon-manganese steel, stainless steels of various grades, titanium and titanium alloys, nickel, Hastelloy alloys, zirconium, and their composite materials. The main material of the reactor, the dimensions and number of openings on the vessel body and lid, the heating method, the internal structure of the reactor, the stirring speed, and the shape of the agitator blades can all be designed according to user requirements. Heating methods available for customization include jacket steam heating, jacket thermal oil electric heating, jacket oil bath circulation, and far-infrared heating, allowing users to select the most suitable option when placing an order. For hydrogenation reactors with polished inner surfaces, the inner surface can achieve a mirror-polished finish. For high-viscosity materials, the reactor can be designed with a conical bottom, facilitating discharge and cleaning. Based on their manufacturing structure, hydrogenation reactors can be categorized into three major types: open-type flat-head reactors, open-type elliptical-head reactors, and closed-type reactors. Each structural type has its own specific application range as well as advantages and disadvantages.

　　Working pressure: -0.1–15.0 MPa

　　Jacket pressure: 0.1–1.6 MPa

　　Operating temperature: Room temperature - 300℃

　　Heating methods include jacket steam, jacket thermal oil electric heating tubes (or circulation), far infrared, external half-coil, and other various heating methods. The heater is equipped with explosion-proof features.

　　Cooling method: Jacket cooling or internal coil cooling

　　Stirring speed: 20–500 rpm; can be equipped with explosion-proof motors and variable-frequency speed control.

　　Agitator types: self-priming, propeller-type, paddle-type, anchor-type, turbine-type, and others.

　　The reactor lid features a conventional opening design: the stirring port is equipped with a magnetic stirrer; the gas-phase port is fitted with a needle valve (for filling with various suitable gases or for vacuum extraction); the hydrogen inlet is also equipped with a needle-type valve. Inside the reactor, there’s a distributor, and the liquid-phase port is fitted with a needle valve and an immersed bottom tube (used for sampling during the reaction or for discharging materials). The feed port is equipped with a threaded plug. The pressure safety and explosion-proof port is fitted with a pressure gauge and a rupture disc. The temperature-control port is equipped with a protective sheath containing a platinum resistance thermometer. The cold-water coil inlet and outlet inside the reactor are fitted with water nozzles. The bottom discharge port is equipped with a valve (the valve type depends on the medium—solid materials require ball valves, while liquid materials can use gate valves).

　　The control system manages the temperature inside the reactor, featuring PID regulation with auto-tuning, intelligent programmed temperature ramping, and precise control of the stirring speed. It is equipped with a heating voltmeter, a motor ammeter, a reactor stirring speed meter, and a display showing the operating time. The system can be integrated with continuous-operation control systems such as gas booster pumps, constant-pressure feeding systems, condensation-reflux collection systems, high-pressure separation units, overpressure and overtemperature alarms, computer-based remote control, and data acquisition and recording functions.

　　The main materials used for the reactor vessel include various grades of austenitic stainless steel, nickel-based alloys, zirconium, titanium and titanium alloys, Hastelloy, Monel alloy, Inconel alloy, aluminum and aluminum alloys, duplex stainless steel, tantalum, and more. The interior can also be coated with polytetrafluoroethylene (PTFE) for applications where the operating temperature is below 200°C.
