The 4A molecular sieve (Na₁₂[(AlO₂)₁₂(SiO₂)₁₂]·27H₂O) is widely used in gas drying, purification, and separation due to its uniform 3.8Å pore size. However, its operating pressure range critically impacts adsorption efficiency, lifespan, and safety. This…
Activated alumina is the most widely used desiccant material for industrial drying. More than 80% of industrial air compressor drying equipment uses activated alumina as the core drying medium, and its conventional drying…
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…
Desulfurization-specific molecular sieve is a sodium X-type silicoaluminate with a crystal pore size of 9-10A (0.9nm), capable of adsorbing molecules with a critical diameter no larger than its own pore size. It is…
In PET (polyethylene terephthalate) resin production – particularly for bottle-grade, sheet-grade, and heavy metal-free food-contact applications – maintaining ultra-high purity is non-negotiable. 4A molecular sieves (pore size: 4Å) serve as the unsung heroes in…
Cryogenic air separation technology is an industrial process that uses the principle of cryogenic distillation to separate air into high-purity oxygen, nitrogen and rare gases. There is a key point in the…
Introduction The separation of methane (CH₄) and carbon dioxide (CO₂) is a critical process in various industries, most notably in natural gas purification and biogas upgrading. The presence of CO₂ reduces the…
Abstract: In the production of high-purity gases, particularly nitrogen, the removal of trace oxygen is a critical step. While catalytic deoxygenation using hydrogen is common, it introduces complexity and safety concerns. This…
Xintao powder molecular sieve, with their efficient adsorption properties, effectively extend the curing cycle of polyurethane adhesives, addressing the critical issue of “difficulty controlling curing time” during polyurethane adhesive production and application. This…
