Desulfurization shaandhaynta molecular shaandho, oo sidoo kale loo yaqaan shaandhada shaandhada molecular skid, waa aalad muhiim u ah nadiifinta gaaska dabiiciga ah ama qaboojinta gaaska dabiiciga ah. Shaandho molecular waa crystal aluminosilicate crystal ah qaab-dhismeedka qaab-dhismeedka iyo qaab-dhismeedka microporous lebbisan. Marka gaaska quudinta ee ka kooban biyaha raadku uu dhex maro sariirta shaandhada molecular ee heerkulka qolka, biyaha raadraaca iyo mercaptan waa la nuugo, sidaas darteed hoos u dhigista biyaha iyo mercaptan-ka ku jira gaaska quudinta, iyada oo la ogaanayo ujeedada fuuq-baxa iyo desulfurization. Habka adsorption ee shaandho molecular waxaa ka mid ah uumi xididka iyo adsorption jirka oo ay sababtay van der Waals Force. Marka la eego isla'egta Kelvin, waxaa laga arki karaa in uumiga xididku daciifo kor u kaca heerkulka, halka adsorption-ka jireed uu yahay habka exothermic, iyo xayeysiistiisu waxay daciifisaa kororka heerkulka waxayna kordhisaa cadaadiska korodhka; Sidaa darteed, habka xayeysiiska ee shaandhada molecular waxaa badanaa lagu fuliyaa heerkul hooseeya iyo cadaadis sare, halka dib-u-soo-nooleynta dib-u-celinta lagu fuliyaa heerkul sare iyo cadaadis hoose. Hoosta ficilka heerkulka sare, gaaska dib u soo kabashada ee nadiifka ah iyo cadaadiska hooseeya, xayeysiiska shaandhada molecular wuxuu sii daayaa adsorbate ee micropore ee socodka gaaska cusboonaysiinta ilaa qadarka adsorbate ee adsorbent uu gaaro heer aad u hooseeya, wuxuuna awood u leeyahay inuu nuugo biyaha iyo mercaptan gaaska quudinta, isagoo ogaanaya habka dib u soo kabashada iyo dib-u-warshadaynta molecular.

Habka farsamada

Socodka gaaska molecular gaaska dabiiciga ah desulphurization shaandho (desulfurization) skid ayaa lagu muujiyay jaantuska. Cutubku waxa uu qaataa saddex hab oo taawar ah, hal minaarad xayeysiis ah, hal tawer oo dib u soo noolayn ah iyo hal qaboojin. Ka dib markii ay ka saareen dareeraha hydrocarbon ee ku dhex jira kala soocida gaaska quudinta, gaaska quudinta wuxuu galaa munaaradda desulfurization shaandho molecular. Biyaha iyo mercaptan ee ku jira gaaska quudinta waxaa lagu dhejiyaa shaandhada molecular si loo xaqiijiyo fuuq-baxa iyo habka adsorption mercaptan. Gaaska la safeeyey ee fuuq-baxa iyo ka saarista mercaptan waxay gashaa shaandhada gaaska alaabta si ay uga saarto boodhka shaandhada molecular, ka dibna waxa loo dhoofiyaa sidii gaaska alaabta.

Shaandhooyinka molecular waxay u baahan yihiin in dib loo soo nooleeyo ka dib marka la isku daro xaddi gaar ah oo biyo ah iyo mercaptan. Ka dib marka la sifeeyo boodhka gaaska alaabta, qayb ka mid ah gaaska alaabta ayaa laga soo saaraa sidii gaas dib-u-kicin ah. Ka dib markii gaaska la kululeeyo 300 ℃ by foornada kulaylka, munaaraddii si tartiib tartiib ah loo kululeeyaa 272 ℃ iyada oo munaaraddii desulfurization shaandheeyo shaandheeyo kelli kaas oo dhammeeyey geeddi-socodka adsorption hoose ilaa sare, si ay biyaha iyo mercaptan adsorbed shaandho kelli waa la kala sooci karaa oo ay noqdaan gaasta dib u soo nooleynta hodan ah si ay u dhamaystiraan geeddi-socodka dib-u-cusboonaysiinta.
