Is molecular sieve molecular sieve or zeolite?

Let me do the clarification. :lol Compare it according to Wikipedia’s definition: A molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids. Often they consist of aluminosilicate minerals, clays, porous glasses, microporous charcoals, zeolites, active carbons, or synthetic compounds that have open structures through which small molecules, such as nitrogen and water can diffuse. Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents. It can be seen that molecular sieve includes zeolite, and zeolite only refers to silica-aluminum molecular sieve. Echo's answer is absolutely correct! :victory::victory: The author of this question originally intended it to be silica-aluminum molecular sieve. The question was not rigorous and led to misjudgment. I would like to express my most sincere apology to Echo. :loveliness::L:hug::kiss:

I didn't know much about these two words at first, but I came into contact with molecular sieve more at work. There were also spelling errors in the kick-off-the-floor activity (sieve was misspelled as sei ve). No wonder OLIVETREE said my answer was wrong. If you have any questions, please post to discuss. I don’t know it all here. :handshake :handshake

In the Chinese-English Petroleum Dictionary: 1. molecular flow 2. molecular sieve 3. zeolite all mean molecular sieves. The most frequently used and more common one is: molecular sieve

First of all, please clarify a concept, what is a molecular sieve?: It uses the principle of different molecular pore sizes to screen substances of different molecules. There are two types of molecular sieves: One type is zeolite molecular sieves and the other type is carbon molecular sieves. Then it’s easy to translate: Zeolite molecular sieve = zeolite molecular sieve (ZMS for short) Carbon molecular sieve = carbon molecular sieve (CMS for short) In addition, when the name molecular sieve was invented, there was only the first type of molecular sieve, so at that time, molecular sieve was = molecular sieve. That is, all molecular sieves that appear in foreign languages ​​​​all refer to zeolite molecular sieves. About zeolite: refers to zeolite. Zeolite is originally a natural mineral, a natural molecular sieve with porous constant pore size. Later, scientists invented a method to artificially synthesize zeolite. Generally in foreign languages, zeolite refers to natural zeolite. As for synthetic zeolite (that is, the first type of molecular sieve), the complete translation is zeolite molecular sieve, and sometimes molecular sieve is also used when there is no ambiguity.

The plural form of molecular sieves is usually used. This is used in air separation. When I was doing my graduation project in college, my tutor also recommended using this.
