13X Molecular Sieve for CO₂ Removal: The Ultimate Industrial Solution

Introduction

CO₂ contamination is a critical challenge in gas processing, affecting industries from natural gas purification to medical oxygen production. 13X molecular sieve, with its superior adsorption capacity and selectivity, has emerged as the go-to solution for efficient CO₂ removal. This article explores why XINTAO's 13X sieve outperforms alternatives and how it can optimize your operations.

Why 13X Molecular Sieve?

1.Large Pore Structure (9Å)

Captures CO₂ molecules (kinetic diameter: 3.3Å) while excluding larger contaminants.

Outperforms Type A sieves (4Å pores) in handling bulkier gas streams.

2.Exceptional Adsorption Capacity

Static CO₂ adsorption: >17% (per HG/T 2690-1995 standard).

Maintains efficiency even at low CO₂ concentrations (<500 ppm).

3.Thermal & Chemical Stability

Withstands temperatures up to 300°C during regeneration.

Resists degradation in acidic gas environments (e.g., H₂S mixtures).

Key Applications

1. Natural Gas Processing

Problem: CO₂ reduces BTU value and corrodes pipelines.

Solution: 13X sieve removes CO₂ to <2 ppm, meeting pipeline specifications.

2. Air Separation Plants

Pre-purification: Protects cryogenic equipment by eliminating CO₂ and moisture (dew point: <-120°C).

3. Biogas Upgrading

Converts raw biogas (30–50% CO₂) into high-purity methane (>97%).

4. Industrial CO₂ Recovery

Captures CO₂ from flue gases for reuse in beverages or dry ice production.

Regeneration & Longevity

Thermal Swing Adsorption (TSA): Heat to 250–300°C under inert gas to desorb CO₂.

Pressure Swing Adsorption (PSA): Reduce pressure for energy-efficient regeneration.

Lifespan: 3–5 years with proper maintenance (vs. 1–2 years for activated alumina).

XINTAO's Competitive Edge

Customizable Forms: Beads (1.6-2.5/3–5mm), pellets (1.6/3.2 mm), or powder for specific reactors.

Quality Assurance:

Crushing strength >85 N/pellet (prevents dusting).

Wear ratio <0.2% (extends bed life).

Global Validation: Used in Shell's LNG plants and Air Liquid's oxygen generators.

Conclusion

For industries demanding high-purity gas and cost-effective CO₂ removal, XINTAO's 13X molecular sieve delivers unmatched performance. Its large pores, high capacity, and robust regeneration make it the ideal choice for harsh industrial environments.
