I-ZnO desulfurization Catalyst enekhwalithi ephezulu kanye nentengo yokuncintisana

I-HL-306 isetshenziswa ekususeni i-sulfurization yamagesi aqhekeka ezinsalela noma ama-syngas kanye nokuhlanzwa kwamagesi okuphakelayo

izinqubo ze-organic synthesis.Ilungele kokubili izinga lokushisa eliphezulu (350–408°C) nangaphansi (150–210°c) ukusetshenziswa.

Ingakwazi ukuguqula isibabule semvelo esilula kuyilapho imunca isibabule esingaphili emgudwini wegesi.Ukusabela Main of the

inqubo desulfurization imi kanje:

(1) Ukusabela kwe-zinc oxide ne-hydrogen sulfide H2S+ZnO=ZnS+H2O

(2) Ukusabela kwe-zinc oxide ngezinye izinhlanganisela zesibabule ezilula ngezindlela ezimbili ezingenzeka.

4. Isimo Esijwayelekile sokuSebenza

I-Feedstock: i-synthesis gas, igesi yenkundla kawoyela, igesi yemvelo, igesi yamalahle.Ingaphatha umfudlana wegesi ngesibabule esingaphili njengephezulu

njengo-23g/m3 enedigri yokuhlanza egculisayo.Ingase futhi ihlanze ukusakaza kwegesi kufika ku-20mg/m3 kokulula kangako

i-organic sulfur njenge-COS ukuya ngaphansi kuka-0.1ppm.

5.Iyalayisha

Ilayisha ukujula: I-L/D Ephakeme (min3) iyanconywa.Ukucushwa kwama-reactor amabili ochungechungeni kungathuthukisa ukusetshenziswa

ukusebenza kahle kwe-adsorbent.

Ilayisha inqubo:

(1)Hlanza i-reactor ngaphambi kokulayisha;

(2)Beka amagridi amabili angenabala anosayizi omncane we-mesh kune-adsorbent;

(3)Layisha ungqimba ongu-100mm we-Φ10—20mm wamaphanorama-refractory kumagridi angenabala;

(4)Skrini i-adsorbent ukuze ususe uthuli;

(5)Sebenzisa ithuluzi elikhethekile ukuqinisekisa ukusatshalaliswa ngokulinganayo kwe-adsorbent embhedeni;

(6)Hlola ukufana kombhede ngesikhathi sokulayisha.Lapho kudingeka ukusebenza kwangaphakathi kwereactor, Ipuleti lokhuni kufanele lifakwe kwi-adsorbent ukuze opharetha ame kulo.

(7)Faka Igridi engagqwali enosayizi wemeshi encane kune-adsorbent kanye nongqimba oluyi-100mm lwamaphanorama-refractory angu-Φ20—30mm phezulu kombhede we-adsorbent ukuze uvimbele ukungena kwe-adsorbent futhi uqinisekise.

ngisho nokusatshalaliswa komfudlana wegesi.

6.Ukuqala

(1)Shintsha uhlelo nge-nitrogen noma amanye amagesi angasebenzi kuze kube yilapho ukugcwala komoyampilo egesini kuba ngaphansi kuka-0.5%;

(2)Shisisa kuqala umfudlana wesiphakeli nge-nitrogen noma igesi yokuphakelayo ngaphansi kwengcindezi ezungezile noma ephakeme;

(3)Isivinini sokushisa: 50°C/h ukusuka kumazinga okushisa asekamelweni kuya ku-150°C (nge-nitrogen);150°C amahora angu-2 (uma isisetshenziswa sokushisisa sinjalo

ishintshelwe kwigesi yokudla), 30°C/h ngaphezu kuka-150°C kuze kufike izinga lokushisa elidingekayo.

(4) Lungisa ingcindezi kancane kancane kuze kube yilapho umfutho wokusebenza ufinyelelwa.

(5) Ngemuva kokushisisa kwangaphambili nokuphakama komfutho, isistimu kufanele iqale isetshenziswe ngomthwalo oyingxenye amahora angu-8.Bese uphakamisa i

layisha kancane kancane lapho ukusebenza kuzinza kuze kube yilapho kusebenza ngokugcwele.

7.Vala

(1)Ukunikezwa kwegesi yokuvala shaqa okuphuthumayo (uwoyela).

Vala ama-valve angenayo kanye ne-outlet.Gcina izinga lokushisa nengcindezi.Uma kunesidingo, sebenzisa i-nitrogen noma i-hydrogen-nitrogen

igesi ukugcina ukucindezela ukuvimbela ukucindezela okubi.

(2) Ukuguqulwa kwe-adsorbent ye-desulfurization

Vala ama-valve angenayo kanye ne-outlet.Yehlisa kancane izinga lokushisa nokucindezela esimweni se-ambient.Bese uhlukanisa i-

i-desulfurization reactor evela ohlelweni lokukhiqiza.Faka esikhundleni i-reactor ngomoya kuze kube yilapho kutholakala umoya-mpilo ongaphezu kwama-20%.Vula i-reactor bese ukhulula i-adsorbent.

(3) Ukugcinwa kwezisetshenziswa (ukulungiswa kabusha)

Qaphela inqubo efanayo njengoba kukhonjisiwe ngenhla ngaphandle kokuthi ukucindezela kufanele kwehliswe ku-0.5MPa/10min kanye nezinga lokushisa.

kwehliswe ngokwemvelo.

I-adsorbent engalayishiwe izogcinwa izendlalelo ezihlukene.Hlaziya amasampula athathwe kusendlalelo ngasinye ukuze unqume

isimo kanye nempilo yesevisi ye-adsorbent.

8.Ezokuthutha kanye nesitoreji

(1) Umkhiqizo we-adsorbent upakishwe kupulasitiki noma emiphongolweni yensimbi enolwelwesi lwepulasitiki ukuvikela umswakama kanye namakhemikhali.

ukungcola.

(2) Ukudilika, ukungqubuzana kanye nokudlidliza okunodlame kufanele kugwenywe ngesikhathi sokuthutha ukuze kuvinjelwe ukuguquguquka

i-adsorbent.

(3)Umkhiqizo we-adsorbent kufanele uvinjelwe ukuthintana namakhemikhali ngesikhathi sokuhamba nokugcinwa.

(4) Umkhiqizo ungagcinwa iminyaka emi-3-5 ngaphandle kokuwohloka kwezakhiwo zawo uma uvalwe ngokufanelekile.
