Engineered solutions designed to meet critical purification tolerances across key global industries.
An in-depth chemical and physical review of type X faujasite zeolites optimized for high-pressure gas separation systems.
Molecular Sieve 13X HP (High Pressure/High Performance) represents an advanced engineering evolution of the standard synthetic Type X crystalline aluminosilicate. Featuring an effective pore diameter of approximately 10 Angstroms (1.0 nm), this molecular sieve is defined by its cubic crystal structure (Faujasite framework) and a high silica-to-alumina ratio. The "HP" variant is specifically manufactured to withstand demanding pressure fluctuations during cyclic adsorption processes, demonstrating superior mechanical integrity and optimized kinetic properties compared to standard industrial-grade adsorbents.
The operating principle of Molecular Sieve 13X HP in air separation and gas purification processes relies on the preferential electrostatic interaction between the polarizable molecules in the gas stream and the extra-framework metal cations (predominantly sodium, and in modified variants, lithium or calcium) situated within the zeolite cage. Nitrogen ($N_2$) possesses a distinct quadrupole moment ($1.49 \times 10^{-40} \text{ C}\cdot\text{m}^2$) that interacts more intensely with the local electrostatic fields of the 13X HP cavities than Oxygen ($O_2$, $0.39 \times 10^{-40} \text{ C}\cdot\text{m}^2$). Under elevated operating pressures, this differential interaction creates a rapid separation kinetic: $N_2$, along with moisture ($H_2O$), carbon dioxide ($CO_2$), and trace hydrocarbons, is bound inside the crystalline structure, while a highly purified stream of $O_2$ flows through the process bed.
A key factor differentiating the 13X HP grade from conventional molecular sieves is its shorter Mass Transfer Zone (MTZ). The optimized bead size distribution, high macroporosity, and enhanced diffusion pathways inside the spheres allow for rapid adsorption kinetics. This prevents premature gas breakthrough, allowing system designers to minimize vessel size or maximize cycle times without risking product purity. Additionally, the thermal stability of the aluminosilicate framework ensures that regeneration processes—typically carried out at temperatures between 200°C and 350°C in Thermal Swing Adsorption (TSA)—do not trigger pore collapse, maintaining stable capacity over thousands of operating hours.
Integrating 13X HP Molecular Sieve systems to optimize yield, purity, and energy metrics globally.
Maximizes oxygen yield in Vacuum Pressure Swing Adsorption (VPSA) and Pressure Swing Adsorption (PSA) units. Provides up to 93-95% oxygen purity for metallurgy, wastewater treatment, and clinical setups by exhibiting high nitrogen dynamic capacity under high flow rates.
Protects downstream cryogenic cold boxes from freezing hazards by removing trace moisture ($H_2O$), carbon dioxide ($CO_2$), and volatile hydrocarbons (such as acetylene, $C_2H_2$) to sub-ppm levels before the gas enters the liquefaction phase.
Serves as a robust polishing agent in steam methane reforming (SMR) operations, removing carbon monoxide ($CO$), trace nitrogen, and residual methane to produce fuel-cell grade hydrogen.

Better air, Better life - Driving green chemistry initiatives for clean air technology.
Ensuring delivery stability and on-the-ground technical services across vital geographical hubs.
Each geographical region presents distinct operational demands for separation adsorbents:
Navigating regulatory compliance is a key requirement for modern chemical supply chains. Our products are fully registered under EU REACH, US EPA TSCA, and other localized regulations, facilitating clean imports. With strategic distribution partnerships globally, we help minimize inventory lead times and support customers with on-site system diagnostics and regeneration adjustments.
Our commitment to advancing clean energy and carbon reduction through next-generation molecular sieve technology.
As industrial demand shifts toward cleaner practices, JOOZEO's R&D focus is evolving to meet these challenges:
We are developing high-purity lithium-exchanged LSX structures that exhibit an even higher nitrogen-to-oxygen separation factor, allowing VPSA units to operate at reduced pressures and save power.
By tailoring pore dimensions and cation distributions, we aim to design zeolites with high selectivity for $CO_2$ over nitrogen under wet gas conditions, supporting industrial carbon capture initiatives.
Our manufacturing sites are transitioning to low-emission calcination processes, helping our clients reduce the indirect Scope 3 emissions associated with their procurement chains.
