Desiccant Dryer Dehydration 4A Zeolte Molecular Sieve

Tsanangudzo Pfupi:

Molecular sieve 4A inokodzera kuomeswa kwegasi (semuenzaniso: gasi rechisikigo, peturu gasi) uye zvinwiwa, ine aperture inosvika mana angstroms.

Nheyo yekushanda yemasefa yemamorekuru inonyanya kuenderana nehukuru hwepore hwema molecular sieves, ayo ari 0.3nm/0.4nm/0.5nm zvichiteerana. Vanogona adsorb gasi mamorekuru ayo molecular dhayamita idiki pane pore saizi. Iyo yakakura saizi yehukuru hwepore, iyo yakakura iyo adsorption kugona. Kukura kwepore kwakasiyana, uye zvinhu zvinosefa nekuparadzaniswa zvakasiyanawo. Mumashoko akareruka, 3a molecular sieve inogona kungoshambadza mamorekuru pazasi 0.3nm, 4a molecular sieve, adsorbed mamorekuru anofanirawo kunge ari pasi pe0.4nm, uye 5a molecular sieve yakafanana. Kana yakashandiswa se desiccant, molecular sieve inogona kutora kusvika ku22% yehuremu hwayo muhunyoro.

Zeolite molecular sieves ine yakasarudzika yakajairwa kristaro chimiro, chimwe nechimwe chine pore chimiro cheimwe saizi uye chimiro, uye ine yakakura chaiyo nzvimbo. Mazhinji zeolite molecular sieves ane yakasimba asidhi nzvimbo pamusoro, uye kune yakasimba Coulomb munda mukristaro pores for polarization. Aya maitiro anoita kuti ive catalyst yakanakisa. Heterogeneous catalytic reactions inoitwa pane yakasimba catalysts, uye iyo inokonzeresa chiitiko chine hukama nehukuru hwekristaro pores yecatalyst. Kana zeolite molecular sieve inoshandiswa sechigadziriso kana chinokonzera mutakuri, kufambira mberi kwemaitiro ekugadzirisa kunotungamirirwa nehukuru hwepore ye zeolite molecular sieve. Saizi uye chimiro chekristaro pores uye pores zvinogona kuita sarudzo mukuita kwekuita. Pasi pemamiriro ezvinhu ekuita, zeolite molecular sieves inoita basa rinotungamira munzira yekuita uye inoratidza chimiro-chakasarudzika catalytic kuita. Kuita uku kunoita kuti zeolite molecular sieves ive itsva catalytic material ine simba rakasimba.
