Masifa emolecularanoshandiswa zvakanyanya mumakemikari uye petrochemical maindasitiri kune akasiyana kupatsanurwa uye kuchenesa maitiro. Imwe yemashandisirwo avo akakosha ndeyekucheneswa kwehydrogen gasi. Hydrogen inoshandiswa zvakanyanya sechikafu mumaindasitiri akasiyana siyana, sekugadzirwa kweammonia, methanol, nemamwe makemikari. Zvisinei, haidhirojeni inogadzirwa nemitoo yakasiyana-siyana haigari yakachena zvakakwana pakushandisa uku, uye inoda kucheneswa kubvisa tsvina yakaita semvura, carbon dioxide, nemamwe magasi. Masefa emolecular anoshanda zvakanyanya mukubvisa tsvina iyi kubva muhova dzehaidhirojeni gasi.

Molecular sieves zvinhu zvine porous izvo zvinokwanisa kusarudza adsorb mamorekuru zvichienderana nehukuru uye chimiro. Iwo ane dhizaini yeakabatana mhango kana ma pores ari eunifomu saizi uye chimiro, izvo zvinovatendera kuti vasarudze adsorb mamorekuru anokwana mumakomba aya. Saizi yemakomba inogona kudzorwa panguva yekubatanidzwa kweiyo molecular sieve, izvo zvinoita kuti zvikwanise kugadzirisa zvivakwa zvavo kune chaiwo maapplication.

Panyaya yekucheneswa kwehydrogen, masefa emamorekuru anoshandiswa kusarudza adsorb mvura uye kumwe kusvibiswa kubva kurwizi rwehydrogen gasi. Iyo molecular sieve inoshambadza mamorekuru emvura uye kumwe kusvibiswa, uku ichibvumira mamorekuru ehydrogen kupfuura. Iyo adsorbed tsvina inogona kubva yabviswa kubva kune molecular sieve nekuipisa kana nekuichenesa nerukova rwegasi.

Iyo inonyanya kushandiswamolecular sieveyekunatswa kwehydrogen imhando ye zeolite inonzi 3A zeolite. Iyi zeolite ine saizi yepore ye 3 angstroms, iyo inobvumira kuti isarudze adsorb mvura uye humwe hutsvina hune hombe mamorekuru saizi kupfuura hydrogen. Iyo zvakare inosarudzika zvakanyanya kumvura, izvo zvinoita kuti ishande zvakanyanya mukubvisa mvura kubva murukova rwehydrogen. Mamwe marudzi emazeolite, akadai se4A uye 5A zeolites, anogona zvakare kushandiswa kucheneswa kwehydrogen, asi iwo haasarudze kumvura uye angangoda tembiricha yepamusoro kana kudzvanywa kwe desorption.

Mukupedzisa, masieve e-molecular anoshanda zvakanyanya mukucheneswa kwehydrogen gasi. Iwo anoshandiswa zvakanyanya mumakemikari uye petrochemical maindasitiri pakugadzira yakakwirira-kuchena hydrogen gasi kune akasiyana maapplication. Iyo 3A zeolite ndiyo inonyanya kushandiswa sefa yemamorekuru yekucheneswa kwehydrogen, asi mamwe marudzi emazeolite anogona zvakare kushandiswa zvichienderana nezvinodiwa zvekushandisa.

Kunze kwezeolites, mamwe marudzi emamorekuru sieves, akadai seakabatidzwa kabhoni uye silica gel, anogona zvakare kushandiswa kuchenesa hydrogen. Zvishandiso izvi zvine nzvimbo yakakwirira yepamusoro uye yakakwira pore vhoriyamu, izvo zvinoita kuti zvinyatso shanda mukushambadza tsvina kubva kune gasi hova. Nekudaro, ivo havasarudze pane zeolites uye vangangoda tembiricha yakakwira kana kudzvanywa kwekuvandudzwa.

Pamusoro pekucheneswa kwehydrogen,molecular sievesanoshandiswawo mune mamwe gasi kupatsanurwa uye kuchenesa maapplication. Iyo inoshandiswa kubvisa hunyoro uye tsvina kubva kumhepo, nitrogen, uye mamwe magasi nzizi. Iwo anoshandiswawo kupatsanura magasi zvichienderana nekukura kwavo kwema molecular, sekuparadzaniswa kweokisijeni uye nitrogen kubva kumhepo, uye kupatsanurwa kwemahydrocarbon kubva kune gasi rechisikigo.

Pakazere, masieve emamolekyuli zvinhu zvakasiyana-siyana zvine huwandu hwakawanda hwekushandisa mumakemikari uye petrochemical industries. Iwo akakosha pakugadzirwa kwemagasi akanyanya-kuchena, uye anopa akawanda mabhenefiti pamusoro pechinyakare nzira dzekuparadzanisa, senge kuderera kwesimba rekushandisa, yakakwirira kusarudza, uye nyore kushanda. Nekuwedzera kuri kudiwa kwemagasi akachena-akachena mumaindasitiri akasiyana siyana, kushandiswa kwema molecular sieves kunotarisirwa kukura mune ramangwana.
