ZnO desulfurizasiya Catalizari hamwe nibiciro byiza kandi birushanwe
HL-306 irakoreshwa muguhumanya imyuka isigaye ya gaze cyangwa syngas hamwe no kweza imyuka y'ibiryo kuri
uburyo bwo guhuza ibinyabuzima.Irakwiriye gukoreshwa hejuru (350-408 ° C) no munsi (150-210 ° c) gukoresha ubushyuhe.
Irashobora guhindura sulforo yoroshye kama mugihe ikurura sulfure idafite ingufu mumigezi ya gaze.Igisubizo nyamukuru cya
inzira ya desulfurizasi niyi ikurikira:
(1) Imyitwarire ya okiside ya zinc hamwe na hydrogen sulfide H2S + ZnO = ZnS + H2O
(2) Imyitwarire ya okiside ya zinc hamwe nibintu byoroshye bya sulfure muburyo bubiri bushoboka.

4. Imikorere isanzwe
Ibiryo: gazi ya synthesis, gaze yumurima wa peteroli, gaze gasanzwe, gaze yamakara.Irashobora gutunganya imyuka ya gaze hamwe na sulfure idasanzwe
nka 23g / m3 hamwe nimpamyabumenyi ishimishije.Irashobora kandi kweza imigezi ya gaze kugeza kuri 20mg / m3 byoroshye
sulfure kama nka COS kugeza munsi ya 0.1ppm.
5.Gutwara
Ubujyakuzimu bwimbitse: Birenzeho L / D (min3) birasabwa.Iboneza rya reaction ebyiri murukurikirane zirashobora kunoza imikoreshereze
imikorere ya adsorbent.
Uburyo bwo gupakira:
(1) Sukura reaction mbere yo gupakira;
(2) Shyira gride ebyiri zidafite ingese nubunini bwa mesh kurenza adsorbent;
.
(4) Erekana adsorbent kugirango ukureho umukungugu;
(5) Koresha igikoresho kidasanzwe kugirango wemeze gukwirakwiza adsorbent mu buriri;
(6) Kugenzura uburinganire bwigitanda mugihe cyo gupakira.Iyo ibikorwa-byimbere bikenewe, isahani yimbaho igomba gushyirwa kuri adsorbent kugirango uyikore ahagarare.
.
ndetse no gukwirakwiza imigezi ya gaze.
6.Tangira
(1) Simbuza sisitemu na azote cyangwa indi myuka ya inert kugeza igihe umwuka wa ogisijeni uri muri gaze uri munsi ya 0.5%;
(2) Shyushya ibiryo bigaburira azote cyangwa gazi yo kugaburira munsi yumuvuduko ukabije cyangwa hejuru;
(3) Umuvuduko wo gushyushya: 50 ° C / h kuva ubushyuhe bwicyumba kugeza kuri 150 ° C (hamwe na azote);150 ° C kuri 2 h (iyo gushyushya ibikoresho ni
yimuriwe kugaburira gaze), 30 ° C / h hejuru ya 150 ° C kugeza ubushyuhe bukenewe bugerweho.
(4) Hindura igitutu ushikamye kugeza igitutu cyibikorwa kigeze.
(5) Nyuma yo gushyushya mbere no kuzamura umuvuduko, sisitemu igomba kubanza gukorerwa igice cyumutwaro kuri 8h.Noneho uzamure
umutwaro ushikamye mugihe ibikorwa bihamye kugeza ibikorwa byuzuye.
7.Gufunga
(1) Gutanga byihutirwa gaze (peteroli) itangwa.
Funga inleti zisohoka.Komeza ubushyuhe n'umuvuduko.Niba ngombwa, koresha azote cyangwa hydrogen-azote
gaze kugirango ikomeze igitutu kugirango ikumire umuvuduko mubi.
(2) Guhindura-hejuru ya desulfurisation adsorbent
Funga inleti zisohoka.Komeza ugabanye ubushyuhe nigitutu kumiterere y'ibidukikije.Noneho hitamo
reaction ya desulfurisation kuva muri sisitemu yo gukora.Simbuza reaktor n'umwuka kugeza ogisijeni ya> 20% igerweho.Fungura reaction hanyuma upakurure adsorbent.
(3) Kubungabunga ibikoresho (kuvugurura)
Itegereze inzira imwe nkuko bigaragara hejuru usibye ko igitutu kigomba kugabanuka 0.5MPa / 10min na temp.
yamanutse bisanzwe.
Adorbent yapakuruwe igomba kubikwa mubice bitandukanye.Gisesengura ingero zafashwe kuri buri cyiciro kugirango umenye
imiterere na serivisi ubuzima bwa adsorbent.
8.Gutwara no kubika

adsorbent.
(3) Ibicuruzwa byamamaza bigomba kubuzwa guhura n’imiti mugihe cyo gutwara no kubika.
(4) Igicuruzwa gishobora kubikwa imyaka 3-5 nta kwangirika kwumutungo wacyo niba bifunze neza.
Kubindi bisobanuro birambuye kubyerekeye produtcts, nyamuneka ntutindiganye kundeba.
