Overview
As a wholly owned subsidiary of Luoyang Jalon Micro-Nano New Materials Co., Ltd. (Stock Code: 688357), Jianyang Technology leverages the parent company’s strong expertise in molecular sieve materials. With professional technical services and continuous innovation in applications, we provide energy-efficient gas separation solutions based on molecular sieves.
Jianyang Technology has been recognized as a National High-Tech Enterprise and a Henan Provincial Technology-based SME, and has actively participated in the development of industry standards. We help customers achieve stable operation, optimized performance, and long-term reliability in gas separation applications.
Leveraging the parent company’s high-performance gas separation molecular sieves, Jianyang Technology utilizes Pressure Swing Adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA) technologies to deliver advanced oxygen generation systems.
Based on specific customer requirements, we design and deliver customized oxygen generation solutions that are widely used in metallurgy, chemical processing, environmental protection, and healthcare. These systems are capable of supplying oxygen with purities ranging from 80% to 95%.
For hydrogen purification system upgrades and optimization, Jianyang Technology selects adsorbents for impurity removal based on the particular hydrogen-rich feed gas sources. We adapt to various process routes and operating conditions to develop highly compatible process solutions aimed at reducing energy consumption, improving hydrogen recovery, and delivering tangible economic value to customers.

The VPSA-2 oxygen generation unit was commissioned in 2012 with a design capacity of 4,000 Nm³/h and a specified oxygen purity of 90%. The system adopts vertical axial-flow adsorption towers. Since October 2018, oxygen purity gradually declined from 89% to 37.7% due to adsorbent performance degradation. To restore system performance, Jianyang Technology carried out a full adsorbent replacement.
After the upgrade, the unit started up successfully on the first attempt, with operating performance exceeding the original design specifications. The Oxygen flow rate reached 4,100 Nm³/h, with a purity of 91%.
In September 2024, Jianyang Technology signed a cooperation agreement with a Shandong-based company to replace the imported adsorbent used in its propane dehydrogenation (PDH) PSA hydrogen purification unit with JLPD5, the next-generation molecular sieve for hydrogen purification, at equivalent bed loading.
After an extended period of stable operation under non-tail-gas-recycle conditions, the unit maintained an average hydrogen recovery above 89%, and product hydrogen purity remained above 99.99%. All performance indicators met the original process design requirements.
The verified operating results enabled optimized unit performance and generated measurable economic benefits for the customer.
