Direct supply line from our Pingxiang manufacturing base for chemical separation units, air prep systems, and high-purity packed beds.
Type 13X (Sodium Faujasite, NaX) features an effective aperture of ~10 Ångströms (1.0 nm). This structural geometry supports heavy duty co-adsorption of CO₂ and H₂O along with complex hydrocarbons.
Characterized by a crystalline cubic lattice with large cavities interconnected by 12-membered oxygen rings. The resulting void volume (up to 50%) allows superior physical capture of critical foulants like mercaptans, aromatics, and nitrous oxide (N₂O).
Thermal swing adsorption (TSA) regimes require efficient desorption cycles. Zhongtai's optimized synthesis maintains structural integrity during repetitive temperature spikes up to 300°C, lowering thermal cycle operational costs by up to 12%.
Bed attrition is the leading cause of pressure drop build-up in deep catalytic columns. Zhongtai's proprietary attapulgite binder matrix yields radial crush strength exceeding 65 N/bead (for 3-5mm spherical fractions), minimizing operational fines.
Operating from Pingxiang, Jiangxi—the chemical media capital of Asia—Zhongtai converges raw materials, automated kilns, and real-time crystalline XRF analysis.
Our multi-zone calcination lines feature SCADA temperature feedback loops (±1.5°C margin), preventing phase transition to amorphous structures while preserving specific pore volumes.
Direct raw material pipeline: kaolin, sodium silicate, and aluminate reactants sit within a 50-kilometer industrial radius, sheltering purchasers from global spot shipping swings.
Every batch undergoes strict attrition rate testing (ASTM D4058), dynamic CO₂ adsorption capacity validation, and residual moisture Karl Fischer titration before packaging.
Market reference pricing (FOB Shanghai/Shenzhen/Qingdao ports) based on volume thresholds and application tiers for industrial buyers.

Engineered zeolite media customized for critical process conditions, avoiding column channeling and premature solvent contamination.
Trace moisture, carbon dioxide, and hydrocarbon leakage into cryogenic heat exchangers lead to catastrophic solid freeze-outs. Zhongtai 13X-APG delivers rapid CO₂ kinetic uptake, lowering bed cold spots and preventing explosive acetylene accumulation in liquid oxygen sumps.
Eliminating hydrogen sulfide (H₂S), methyl/ethyl mercaptans, and dimethyl sulfide (DMS) down to sub-ppm pipeline parameters. Our engineered sieves maintain steady equilibrium capacity in sour gas processing environments with cyclic hydro-thermal stress.
Medical-grade PSA and VPSA systems rely on consistent nitrogen adsorption selectivity over oxygen. Zhongtai 13X-HP creates steeper mass transfer zones (MTZ), facilitating higher recovery ratios with compact column dimensions.
Continuous synthetic formulation research driving lower energy footprints and industrial decarbonization readiness.
By crystallizing inert clay binders into pure Faujasite framework structures, overall active surface area climbs 20–25%, dropping bed packing requirements in weight-sensitive offshore installations.
