The visualization reactor system and the safety electrode‑loading fixed bed, both independently developed by Yanzheng, have received widespread acclaim. This unit is primarily used for conducting hydrogenation experiments on petroleum products under electric field application, collecting data on the effects of temperature and pressure on the reaction, while also visually capturing data on various conditions—including arc characteristics, temperature, voltage, and gas pressure—to assess their impact on the experiment.

R134A Decomposition Device

The R134a decomposition unit is designed for operating pressures up to 25 MPa at a temperature of 650°C, with an actual operating pressure range of 10–20 MPa and an operating temperature of 300–600°C. The unit comprises an inlet gas module, an inlet liquid module, a preheating module, a reaction module, a condensation and separation module, and an automatic pressure control module. A position‑adjustable sieve plate is installed at the bottom of the reactor, allowing both precise adjustment of the catalyst loading and enhanced contact between the catalyst particles and the reactor wall via the sieve plate. Using this unit, the effects of factors such as temperature, pressure, space velocity, catalyst performance, and catalyst particle size on the reaction can be investigated.

Continuous flow reactor

A Continuous Flow Reactor is a piece of equipment that enables continuous feed and continuous product output in chemical reactions. Compared with traditional batch reactors, continuous flow reactors offer numerous advantages, including higher production efficiency, improved safety, and easier process scale-up. A wide range of continuous flow reactors—with multiple capacity levels and diverse functionalities—are available for customization. They feature broad applicability, powerful performance, flexible configuration options, and free configuration recommendations.

Photocatalytic Batch Continuous Reactor

The photothermal catalytic liquid fuel evaluation system is primarily used in continuous-phase photocatalysis, gas–solid photocatalysis, and gas–liquid reaction photocatalysis, achieving excellent results in fields such as pollutant degradation, catalytic synthesis, sulfidation reactions, and thermal catalysis. It is particularly well suited for applications including photocatalytic CO₂ reduction, photoelectrochemical activity evaluation, VOC degradation analysis (including total non-methane hydrocarbon degradation analysis), benzene-series compound degradation analysis, national standard acetaldehyde degradation analysis, formaldehyde photocatalysis, automotive exhaust NOₓ degradation analysis, and photocatalytic nitrogen fixation. YanZheng Instruments can customize complete reaction systems according to customers’ specific process requirements.

Sapphire Experimental Reactor System

A fully transparent, visual lubricant property testing platform capable of online measurement of viscosity, density, and solubility parameters across a temperature range of 10 MPa and -10 to 200°C, with a 300 ml capacity. The equipment includes a heating module, a stirring module, and a high‑ and low‑temperature circulation module.

Fully transparent reactor

The all‑transparent reactor is constructed from high‑strength transparent materials such as high borosilicate glass or sapphire, complemented by an external protective layer made of plastic or metal, ensuring its resistance to high temperatures, corrosion, and enhanced safety. The internal components—including stirring, heat transfer, sealing, and control systems—are similar to those found in conventional reactors. While its operating principle is identical to that of traditional reactors, the transparent design allows for real‑time observation of the reaction process, thereby improving reaction control and product quality. The advantages of all‑transparent reactors include excellent visibility, high control precision, superior safety, and easy cleaning, making them widely used in fields such as chemical research, biopharmaceuticals, materials science, and educational demonstrations.
