Maurafu emotaIzvo zvakakosha zvinhu zvinoshandiswa mune dzakasiyana siyana maindasitiri maitiro ekuparadzanisa mamorekuru zvichienderana nehukuru hwavo uye chimiro. Iwo ari crystalline metal simbi aluminilsilicates ane matatu-dimensicting interconnecting network yeAlumina and silica tetrahedra. Zvinonyanya kushandiswamaurafu emotai 3a uye 4a, iyo inosiyana mune yavo saizi uye mashandisirwo.
4a moreti anonyara ane saizi yepore yeanenge mana angstrom, nepo3a mbeveveIva nehuremu hushoma hwepora hwakatenderedza 3 angstroms. Musiyano wehukuru hwePore hunoguma nemusiyano mukugona kwavo kwekushambadzira uye kusarudza kwemamorekuru akasiyana.4a mbevevevanowanzo shandiswa pakuremerwa kwemagasi uye zvinwiwa, pamwe nekubviswa kwemvura kubva pamhepo uye gasi rechisikigo. Kune rimwe divi, 3A molecular sieves inonyanya kushandiswa pakushayikwa kwehydrocarbons uye polar compounds.
Iko kusiyanisa muhukuru pore zvinokanganisawo mhando dzemamolekyudhi dzinogona kushambidzwa nemhando yega yega yehembeular sosi. 4An Molecular Sies inoshanda mukushambadzira mauri makuru semvura, uye kabhoni dialcarbons, nepo 3a molecularbons, iyo 3a molecular mbichana masisitiri akananga kune madiki madiki semvura, Amonia, uye alcohols. Uku kusarudzika kwakakosha mukushandisa zvirimo uko kwakanangana kusviba kunofanirwa kubviswa kubva musanganiswa wemagasi kana zvinwiwa.
Chimwe chinhu chakakosha kufunga kana uchisarudza pakati3a uye 4a molecular mbimbiKugona kwavo kurwadzisa mazinga akasiyana ezvinoshambadza. 3Amonope manyoro okusiyana-soro kune mupfuti wemvura zvichienzaniswa ne 4a molecular sives, kuvaita kuti vakwanise kunyatsoita zvekushandisa apo kuvapo kwemanyoro kune hanya. Izvi zvinoita 3A molecular sieves yakakodzera kushandiswa mumhepo uye gasi kuomesa maitiro apo kubviswa kwemvura kwakanyanya.
Panyaya yekunyorera maindasitiri, 4a molecular inokonzeresa inoshandiswa mukugadzirwa kweokisijeni uye nitrogen kubva pakuparadzaniswa kwemhepo, pamwe nekuomeswa kwefiriji uye gasi rechisikigo. Kugona kwavo kuwana zvinobudirira mvura uye kabhoni diokonode kunoita kuti vakwane mune aya maitiro. Kune rimwe divi, 3A molecular shandisa zvakanyanya mukuomeswa kwekushomeka kwehydrocarbons, yakadai segesi yakatsemuka, properyle, uye butasiene, uye nekucheneswa kwemvura yemvura petroleum.
Izvo zvakakosha kuti uzive kuti sarudzo pakati pe3A uye 4a molecular sieves zvinoenderana nezvinodiwa zvekushandisa, kusanganisira mhando yemamolekyudhi kuti ishamamwi, iyo yakanyorova yechigadzirwa chinodiwa. Kunzwisisa misiyano pakati peaya manyorerwo anokosha ekusarudza sarudzo yakakodzera kwazvo yeimwe nzira maindasitiri.
Mukupedzisa, nepo zvese zviri zviviri3a uye 4a molecular mbimbiZvakakosha kuti utsinye hwemhepo yakasarudzika uye maitiro ekuzvinatsa, kusiyana kwavo muhukuru pore, kusarudzika kusarudzika, uye kuramba humreity kunovaita kuti vakwanise kusanganisa kusiyanisa kusiyaniswa. Nekunzwisisa misiyano iyi, maindasitiri anogona kuita zvisarudzo zvine ruzivo nezve kusarudzwa uye kushandiswa kwemanyorerwe emolecular sieves kuti vasiye maitiro avo uye kuzadzisa iyo yakadiwa chigadzirwa chakachena.
