I-ZnO desulfurization Catalyst enomgangatho ophezulu kunye nexabiso elikhuphisanayo
I-HL-306 iyasebenza kwi-desulfurization yentsalela yeegesi eziqhekekayo okanye i-syngas kunye nokucocwa kweegesi zesondlo
iinkqubo ze-organic synthesis. Ilungele ukusetyenziswa kobushushu obuphezulu (350–408°C) nangaphantsi (150–210°c).
Iyakwazi ukuguqula isulfure ephilayo elula ngelixa ifunxa isulfure ye-inorganic kumsinga werhasi. Impendulo engundoqo ye
inkqubo desulfurization imi ngolu hlobo lulandelayo:
(1) Ukusabela kwe-zinc oxide kunye ne-hydrogen sulfide H2S+ZnO=ZnS+H2O
(2) Ukusabela kwe-zinc oxide kunye nezinye iikhompawundi zesulfure ezilula ngeendlela ezimbini ezinokwenzeka.

4. IMeko yokuSebenza eqhelekileyo
I-Feedstock: irhasi ye-synthesis, irhasi yentsimi yeoli, igesi yendalo, irhasi yamalahle. Inokuphatha umjelo werhasi ngesulfure engaphiliyo iphezulu
njengoko 23g/m3 kunye isidanga esanelisayo zokucoca. Iyakwazi nokuhlambulula umjelo werhasi ukuya kuthi ga kwi-20mg/m3 yelula ngolo hlobo
sulphur ephilayo njenge-COS ukuya ngaphantsi kwe-0.1ppm.
5.Ilayisha
Ukulayisha ubunzulu: I-L/D ephezulu (min3) iyacetyiswa. Ulungelelwaniso lweereactor ezimbini kuthotho kunokuphucula ukusetyenziswa
ukusebenza kakuhle kwe-adsorbent.
Ilayisha inkqubo:
(1)Coca i-reactor phambi kokulayisha;
(2)Beka iigridi ezimbini ezingenakutyiwa ezinobukhulu obuncinci bemesh kune-adsorbent;
(3)Layisha umaleko oyi-100mm we-Φ10—20mm iisphere ezizii-refractory kwiigridi ezingenasici;
(4)Jonga i-adsorbent ukususa uthuli;
(5)Sebenzisa isixhobo esikhethekileyo ukuqinisekisa ukuhanjiswa ngokulinganayo kwe-adsorbent ebhedini;
(6)Hlola ukufana kwebhedi ngexesha lokulayisha. Xa kufuneka umsebenzi wangaphakathi wereactor, ipleyiti yomthi kufuneka ibekwe kwi-adsorbent ukuze umqhubi ame phezu kwayo.

nokusasazwa komsinga werhasi.
6.Ukuqalisa
(1)Tshintsha inkqubo nge-nitrogen okanye ezinye iigesi ezingasebenziyo de i-oxygen concentration kwigesi ibe ngaphantsi kwe-0.5%;
(2)Tshisa umjelo wesondlo ngenitrogen okanye igesi yefidi phantsi koxinzelelo olungqongileyo okanye oluphakamileyo;
(3)Isantya sokufudumeza: 50°C/h ukusuka kubushushu begumbi ukuya kwi-150°C (ngenitrogen); I-150 ° C ye-2 h (xa i-idium medium ishushu
itshintshelwe kwigesi yokutya), 30°C/h ngaphezulu kwe-150°C de ubushushu obufunekayo bufunyenwe.
(4) Lungisa uxinzelelo ngokuthe chu de uxinzelelo lomsebenzi lufunyenwe.
(5)Emva kokufudumeza kwangaphambili kunye nokuphakama koxinzelelo, inkqubo kufuneka iqale iqhutywe kwisiqingatha somthwalo we-8h. Emva koko phakamisa i
layisha ngokuthe chu xa umsebenzi uzinza de usebenze ngokupheleleyo.
7.Cima
(1)Ubonelelo olungxamisekileyo lokuvala irhasi (i-oyile).
Vala iivalvu zokungena neziphumayo. Gcina ubushushu kunye noxinzelelo. Ukuba kuyimfuneko, sebenzisa initrogen okanye ihydrogen-nitrogen
igesi ukugcina uxinzelelo lokuthintela uxinzelelo olubi.
(2) Ukutshintsha kwe-adsorbent ye-desulfurization
Vala iivalvu zokungena neziphumayo. Yehlisa ngokuthe ngcembe iqondo lobushushu kunye noxinzelelo kwimeko ye-ambient. Emva koko wahlule i
i-reactor desulfurization ukusuka kwinkqubo yemveliso. Buyisela ireactor ngomoya de uxinzeleko lweoksijini engaphezulu kwama-20% lufunyenwe. Vula i-reactor kwaye ukhuphe i-adsorbent.
(3) Ukugcinwa kwezixhobo (ulungiso)
Qwalasela inkqubo efanayo njengoko kubonisiwe ngasentla ngaphandle kokuba uxinzelelo kufuneka luthotywe nge-0.5MPa/10min kunye ne-temp.
ithotywe ngokwemvelo.
I-adsorbent engalayishwanga iya kugcinwa kwimigangatho eyahlukeneyo. Hlalutya iisampulu ezithathwe kumaleko ngamnye ukumisela
ubume kunye nobomi benkonzo ye-adsorbent.
8.Ukuthutha kunye nokugcinwa
