Zvakadini nezve adsorption performance ye4A molecular sieve yeH₂S?Kuti tigadzirise dambudziko reH₂S kusvibiswa kwekunhuhwirira mumarara, Isu tinosarudza yakaderera-yakaderera coal gangue uye kaolin yakasarudzwa, yakagadzirwa 4A molecular sieve ine yakanaka adsorption uye catalytic effect kuburikidza nehydrothermal nzira.Kuedza kwainyanya kudzidza mhedzisiro yekusiyana kwekushisa kwecalcination uye nguva yekristalllization pane adsorption desulfurization performance.
Mhedzisiro yacho inoratidza kuti adsorption desulfurization performance ye4A molecular sieve yakagadzirwa nekaolin zviri pachena kuti iri nani pane yemarasha gangue.Iyo tembiricha yecalcination i900 ℃, tembiricha yecrystallization iri 100 ℃, nguva yecrystallization ndeye 7h, uye chiyero chechinhu kune mvura 1: 7.Kana iyo alkali concentration iri 3mol/L, iyo desulfurization simba inogona kusvika 95mg/g.X-ray diffraction ongororo yakaratidza kuti pakanga paine zviri pachena elemental sarufa hunhu hwepamusoro mumhepo mushure mekushambadza ne4A molecular sieve, zvichiratidza kuti chigadzirwa che4A molecular sieve adsorption yeH 2 S odorous gasi yaive elemental sulfur.
Iyo 4A molecular sieve mukumanikidza swing adsorption iri nyore kuve nechepfu uye kurasikirwa nebasa rayo, zvichiita kuti mudziyo wese umire kushanda.Masefa emamorekuru anoverengera chikamu chikuru chemutengo wePSA, uye mutengo wekuchengetedza weseti yakakwana yemamorekuru sieve PSA okisijeni midziyo inopfumisa inenge yakaenzana nemutengo wekuchengetedza simba.Mumashandisirwo anoshanda, pressure swing adsorption ndiyo tekinoroji yepamusoro, asi midziyo inodhura, sefa ye molecular ine hupenyu hupfupi hwesevhisi, uye midziyo inogadzirwa, Mutengo wakaenzana nekuchengetedza purofiti, izvo zvinoita kuti molecular sieve pressure swing adsorption isingawanike mukushandisa zvinoshanda.
Iyo nitrogen-inogadzira kabhoni mamorekuru e4A molecular sieve pressure swing adsorption midziyo inotapukirwa nyore nyore nemamorekuru emvura, gasi rinoparadza, magasi ane acid, guruva, mamorekuru emafuta, nezvimwewo, zvichikonzera kusashanda kwemamorekuru.Kuwanda kwekusashanda uku hakuchinjiki.Re-activation inogona kuitwa nekupupurutswa nemhepo yakachena uye nemvura kana zvichidiwa, asi kunyange yakagadziriswazve kabhoni mamorekuru anowanzoita mashoma kuita uye kugadzira nitrogen kupfuura yekutanga, inova yatinodaidza kuti molecular sieve poisoning.
