从1954年美国联合碳化物公司(Union Carbide)把三种类型的分子筛产品作为商品试销以来,推动了整个分子筛工业的迅速发展。现在世界上许多国家每年都可以生产数以万吨计的、不同品种和型号的分子筛产品。其中大量使用的为A型、X型、Y型、丝光沸石和具有专门用途的各种特殊型号的分子筛产品。今天分子筛作为吸附剂和催化剂,已广泛的用于化工、石油、冶金、电子、国防等许多领域。 Since 1954, Union Carbide has commissioned three types of molecular sieve products as commercial products, and has promoted the rapid development of the entire molecular sieve industry. Now many countries in the world can produce tens of thousands of tons of different types and types of molecular sieve products every year. A large number of use for the A-type, X-type, Y-type, mordenite and has a special purpose of various special types of molecular sieve products. Molecular sieve as adsorbent and catalyst today, has been widely used in chemical, petroleum, metallurgy, electronics, defense and many other fields.
