Desulfurization ZnO Catalyst oo leh tayo sare iyo qiimo tartan leh
HL-306 waxaa lagu dabaqi karaa nadiifinta haraaga gaaska dilaaca ama syngas iyo nadiifinta gaasaska quudinta
hababka synthesis organic.Waxay ku habboon tahay isticmaalka heerkulka sare (350-408 ° C) iyo ka hooseeya (150-210 ° C).
Waxay u rogi kartaa xoogaa baaruud ah oo organic ka fudud iyadoo la nuugayo baaruudka aan noolaha ahayn ee qulqulka gaaska.Falcelinta ugu weyn ee
Habka desulfurization waa sida soo socota:
(1) Falcelinta zinc oxide ee leh hydrogen sulfide H2S+ZnO=ZnS+H2O
(2) Ka falcelinta zinc oxide oo leh qaar ka mid ah xeryahooda sulfur ee fudud laba siyaabood oo suurtagal ah.

Feedstock: gaaska synthesis, gaaska goobta saliidda, gaaska dabiiciga ah, gaaska dhuxusha.Waxay daweyn kartaa qulqulka gaaska leh baaruud aan organic ahayn mid sare
sida 23g/m3 oo leh shahaado nadiifin oo ku qanacsan.Waxa kale oo ay ku nadiifin kartaa qulqulka gaasta ilaa 20mg/m3 ee sida fudud

5.Loading
Qoto dheeraynta: Sare L/D (min3) ayaa lagula talinayaa.Isku xidhka laba reactors oo taxane ah ayaa wanaajin kara isticmaalka
waxtarka adsorbent.
Habka soo dejinta:
(1) Nadiifi reactor ka hor inta aanad soo shubin;
(2) Ku rid laba xabo oo aan kala lahayn oo leh cabbir mesh ka yar kan adsorbent;
(3) Ku shub lakabka 100mm ee Φ10-20mm ee dhinacyada is-difaacaya ee shabkada aan nadiifka ahayn;
(4) Shaashadda adsorbent-ka si aad boodhka uga saarto;
(5) Isticmaal qalab gaar ah si aad u hubiso si siman u qaybinta adsorbent ee sariirta;
(6) U fiirso labbiska sariirta marka la raraynayo.Marka loo baahdo hawlgalka reactor-gudaha, saxan alwaax ah waa in lagu dhejiyaa adsorbent-ka si uu hawlwadeenku ugu istaago.
(7) Ku rakib shabag aan nadiif ahayn oo leh cabbir yar oo mesh ah oo ka badan xayaysiisyada iyo lakabka 100mm ee Φ20-30mm ee qaybaha kore ee sariirta adsorbent si looga hortago entrainment ee adsorbent oo loo hubiyo
xitaa qaybinta qulqulka gaaska.
6.Bilow
(1) Ku beddel nidaamka nitrogen ama gaasas kale oo aan shaqayn ilaa inta oksijiinta gaaska ku jirta ay ka yar tahay 0.5%;
(2) Ku sii kululee qulqulka quudinta leh nitrogen ama gaas quudin iyadoo la raacayo cadaadiska jawiga ama kor u kaca;
(3) Xawaaraha kuleylka: 50 ° C / h laga bilaabo heerkulka qolka ilaa 150 ° C (oo leh nitrogen);150C ilaa 2 saacadood (marka dhexdhexaadinta kuleylka ay tahay
loo beddelay gaaska quudinta), 30°C/h in ka badan 150°C ilaa heerkulka loo baahan yahay laga gaadho.
(4) Cadaadiska si joogto ah u hagaaji ilaa cadaadiska hawlgalka la gaaro.
(5) Ka dib kulaylka ka hor iyo kor u qaadista cadaadiska, nidaamka waa in marka hore lagu shaqeeyaa nuska nuska ah ee 8h.Dabadeed kor u qaad
si joogto ah u rar marka hawlgalku noqdo mid xasiloon ilaa hawlgal buuxa.
7.Xidhiidh
(1)Gaaska xiran ee degdega ah (saliid).
Xidh furayaasha soo galitaanka iyo kuwa ka baxa.Hayso heerkulka iyo cadaadiska. Haddii loo baahdo, isticmaal nitrogen ama hydrogen-nitrogen
gaaska si loo ilaaliyo cadaadiska si looga hortago cadaadiska xun.
(2) Beddel-ka-beddelka adsorbent-ka nadiifinta
Xidh furayaasha soo galitaanka iyo kuwa ka baxa.Si tartiib ah hoos ugu dhig heerkulka iyo cadaadiska xaalad jawiga.Ka dibna gooni u sooc
reactor desulfurization ka nidaamka wax soo saarka.Ku beddel reactor-ka hawo ilaa la helayo qiyaasta oksijiinta ee>20%.Fur reactor-ka oo soo deji xayaysiisyada
(3) Dayactirka qalabka (dib u habeyn)
U fiirso isla habraaca sida kor ku cad marka laga reebo cadaadiska waa in hoos loo dhigaa 0.5MPa/10min iyo heerkulka.
si dabiici ah hoos loogu dhigay.
Xayeysiinta aan la rarin waa in lagu kaydiyaa lakabyo kala duwan.Falanqee shaybaarada laga soo qaaday lakab kasta si loo go'aamiyo
xaaladda iyo nolosha adeegga ee adsorbent.
8.Gaadiidka iyo kaydinta
(1) Alaabta adsorbent-ka waxaa lagu soo guray caag ama foosto bir ah oo leh dahaar caag ah si looga hortago qoyaanka iyo kiimikada
faddarayn.
(2) Tusbaxa, isku dhaca iyo gariirka rabshadaha wata waa in laga fogaadaa inta lagu jiro gaadiidka si looga hortago jeexjeexa
adsorbent.
(3) Alaabta adsorbent waa in laga ilaaliyaa inay la xiriirto kiimikooyinka inta lagu jiro gaadiidka iyo kaydinta.
(4) Alaabta waxaa lagu kaydin karaa 3-5 sano iyada oo aan la xumeyn hantideeda haddii si habboon loo shaabadeeyo.
