A comprehensive checklist of safety rules for hydrogenation reactors! Click here!

The hydrogenation reactor employs a ring-shaped rare-earth permanent magnet coupling drive, providing high stirring torque that is comparable to mechanical stirring. It features static sealing and zero leakage. The reactor’s main material is stainless steel; depending on the specific medium requirements, it can be fabricated using special materials such as 316L stainless steel, titanium, nickel, tantalum, zirconium, Hastelloy alloys, or PTFE-lined components. The stirring bearings are equipped with self-lubricating, wear-resistant bushings, making them suitable for agitating a wide variety of media. Typically, the heating method is dry-type electric heating; however, at the customer’s request, it can also be configured with thermal oil electric heating or jacketed heating. The reactor comes with a multifunctional digital display control box for temperature and pressure monitoring. The heating system utilizes a PID automatic temperature controller for precise temperature regulation.

Here’s a quick, practical tip—get an overview of a hydrogenation reactor in just one minute!

The hydrogenation reactor is a device used to monitor reaction pressure. This hydrogenation reactor features a small size, a simple and reliable structure, cost-effectiveness, and durability. It comes fully equipped with accessories, including an imported miniature DC motor, pressure gauge, explosion-proof device, inlet valve, sampling valve, and temperature probe. It allows for convenient implementation of micro-reflection experiments. The reactor body and heater can be completely separated, greatly facilitating disassembly of the reactor and enhancing work efficiency.

Categories and Working Principles of Hydrogenation Reactors

In experiments, we often encounter gas purging using nitrogen or hydrogen, or hydrogenation reactions, in which we need to replace the air in the reactor with the desired reaction gas. Generally, there are two common methods: One is to first introduce the required gas, then close the inlet valve and open the exhaust valve; the other is to evacuate the reactor completely and then introduce the gas to be reacted into the laboratory reactor for the reaction. After repeating this process three times, the gas inside the hydrogenation reactor will be fully purged. Next, let’s take a closer look at the working principle of the hydrogenation reactor.

How is the temperature control achieved in a hydrogenation reactor?

The hydrogenation reactor unit is designed with a liquid feed unit, a gas feed unit, a reaction unit, and a collection unit. The feed gas and feed liquid are mixed in a certain proportion and preheated before being fed into the fixed-bed reactor. The feed gas is metered by a mass flow controller, while the feed liquid is metered by a metering pump. The reactor is heated by a three-stage electric heating furnace. After exiting the reaction unit, the reaction products undergo gas-liquid separation first. The liquid phase is sent to a storage tank, while the tail gas is either filtered and vented or routed to an online analyzer.

What factors should be considered when choosing a hydrogenation reactor manufacturer?

For purchasers, when selecting a manufacturer of hydrogenation reactors, it’s important to take a comprehensive approach. After all, there are many manufacturers currently producing hydrogenation reactors. If you make your choice blindly, you might end up with products that haven’t been carefully considered—or even worse, you could end up buying products that don’t meet quality standards. To help you avoid such situations, let’s now discuss the key factors you should consider when making your selection. If you’re interested, keep reading!

Precautions for Using Laboratory Reactors

In the daily use and management of laboratory reactors, failure to follow operating procedures can lead to serious accidents such as personnel injuries and equipment malfunctions. These incidents may include reactor explosions, explosions of reaction products, and release of toxic substances. So, let’s now take a closer look at the precautions for using laboratory reactors!

How to Use a Laboratory Reactor Correctly

A laboratory reactor—a commonly used reactor and versatile reaction vessel in chemical experiments—allows for precise control of critical parameters during a reaction, including temperature, pressure, mechanical conditions, and the concentrations of reactants and products. The laboratory reactors typically used in most labs are designed to handle a wide range of experimental needs. To put it simply: You place various solvents, metals, ligands, and other reagents into the reactor, then subject the mixture to elevated pressure and temperature. This type of reactor can be used for sample pretreatment in analytical techniques such as atomic absorption spectroscopy or plasma emission spectroscopy. It’s also ideal for small-scale synthesis reactions. Moreover, thanks to the reactor’s ability to withstand strong acids and strong bases, as well as its sealed, high-temperature, high-pressure environment, it enables rapid reactions to take place.

Applications of Laboratory Reactors

Laboratory reactors are primarily used in sectors such as petroleum, chemical engineering, pharmaceuticals, metallurgy, scientific research, and universities for conducting high-temperature and high-pressure chemical reaction experiments, enabling processes like hydrolysis, neutralization, crystallization, and distillation. Now, let’s take a closer look at the various applications of laboratory reactors!

Operating Procedures and Precautions for Laboratory Reactors

Laboratory reaction vessels are widely used in industries such as chemical engineering, petroleum, and food processing. Their introduction has fundamentally solved the shaft seal leakage problem—previously insurmountable with packing seals and mechanical seals. Below, we’ll introduce the operating procedures and important precautions for using laboratory reaction vessels.

Precautions for Operating Laboratory Reactors

The stainless steel high-pressure reactor system is a chemical reaction mixing device designed for three-phase processes involving gas-liquid-liquid, liquid-solid, or gas-liquid-solid mixtures. Various chemical raw materials can be thoroughly mixed under high temperature, high pressure, and vacuum conditions, thereby enhancing mass and heat transfer processes.

Working Principle of Laboratory Reactors

The laboratory reactor is a piece of equipment used to carry out chemical reactions in industrial processes. It enables systematic studies of single-phase liquid reactions as well as multiphase chemical reactions involving gas-liquid, gas-liquid-solid, and other combinations. The reactor typically features a stirring device (such as mechanically driven stirrers or stirrers operated by gas flow). When the reactor has a relatively large height-to-diameter ratio, multi-stage impellers can be employed. During the reaction, if heating or cooling of the materials is required, a jacket can be installed on the reactor wall, and heat-exchange surfaces can be incorporated inside the reactor. Alternatively, heat exchange can also be conducted in an external circulation system.
