ZnO desulfurization Catalyst nrog cov khoom zoo thiab cov nqi sib tw
HL-306 muaj feem xyuam rau desulfurization ntawm residue cracking gases los yog syngas thiab purification ntawm pub gases rau
cov txheej txheem organic synthesis. Nws yog tsim rau ob qho tib si siab dua (350-408 ° C) thiab qis dua (150-210 ° c) kub siv.
Nws tuaj yeem hloov qee qhov yooj yim organic sulfur thaum absorbing inorganic sulfur hauv cov dej ntws. Cov tshuaj tiv thaiv tseem ceeb ntawm
Cov txheej txheem desulfurization yog raws li nram no:
(1) Cov tshuaj tiv thaiv zinc oxide nrog hydrogen sulfide H2S + ZnO = ZnS + H2O
(2) Cov tshuaj tiv thaiv zinc oxide nrog qee cov tshuaj sulfur yooj yim hauv ob txoj hauv kev.

Feedstock: synthesis gas, roj teb gas, natural gas, thee gas. Nws tuaj yeem kho cov roj kwj nrog inorganic sulfur li siab
raws li 23g / m3 nrog siab purification degree. Nws kuj tseem tuaj yeem ua kom huv cov pa roj nrog txog 20mg / m3 ntawm qhov yooj yim dua
organic sulfur li COS kom tsawg dua 0.1ppm.
5. Chaw thau khoom
Loading qhov tob: siab dua L/D (min3) yog pom zoo. Kev teeb tsa ntawm ob lub reactors hauv series tuaj yeem txhim kho kev siv
efficiency ntawm lub adsorbent.
Loading txheej txheem:
(1) Ntxuav lub reactor ua ntej loading;
(2) Muab ob daim phiaj stainless nrog mesh me me dua cov adsorbent;
(3) Load 100mm txheej ntawm Φ10-20mm refractory spheres rau ntawm daim phiaj stainless;
(4) Saib cov adsorbent kom tshem tawm cov plua plav;
(5) Siv cov cuab yeej tshwj xeeb los xyuas kom meej qhov sib npaug ntawm cov adsorbent hauv txaj;
(6) Tshawb xyuas qhov sib xws ntawm lub txaj thaum thauj khoom. Thaum ua haujlwm sab hauv-reactor xav tau, Ib lub phaj ntoo yuav tsum muab tso rau ntawm qhov adsorbent rau tus neeg teb xov tooj sawv ntsug.
(7) Nruam Ib daim phiaj stainless nrog mesh me me dua li cov adsorbent thiab 100mm txheej ntawm Φ20-30mm refractory spheres nyob rau sab saum toj ntawm lub txaj adsorbent thiaj li tiv thaiv kev nkag ntawm cov adsorbent thiab xyuas kom meej.
txawm faib cov pa roj.
6.Start-up
(1) Hloov cov txheej txheem los ntawm nitrogen lossis lwm yam tsis muaj zog kom txog thaum cov pa oxygen hauv cov pa tsawg dua 0.5%;
(2) Preheat cov kwj dej nrog nitrogen los yog pub roj nyob rau hauv ambient los yog siab siab;
(3) Cua kub ceev: 50 ° C / h los ntawm chav tsev kub txog 150 ° C (nrog nitrogen); 150 ° C rau 2 h (thaum cua sov nruab nrab yog
Hloov mus rau pub roj), 30 ° C / h tshaj 150 ° C kom txog thaum qhov ntsuas kub xav tau.
(4) Kho lub siab tsis tu ncua kom txog thaum lub siab ua haujlwm tiav.
(5) Tom qab ua ntej cua sov thiab siab siab, lub kaw lus yuav tsum xub ua haujlwm ntawm ib nrab load rau 8h. Ces tsa tus
thauj khoom tsis tu ncua thaum ua haujlwm ruaj khov kom txog thaum ua haujlwm puv.
7. Kaw-down
(1) Kev kaw hluav taws xob kub ceev (roj) khoom.
Kaw inlet thiab qhov hluav taws xob li qub. Khaws qhov kub thiab txias.Yog tias tsim nyog, siv nitrogen lossis hydrogen-nitrogen
gas kom tswj lub siab kom tiv thaiv tsis zoo siab.
(2) Hloov-dhau ntawm desulfurization adsorbent
Kaw inlet thiab qhov hluav taws xob li qub. Tsis tu ncua txo qhov kub thiab txias rau ambient mob. Ces cais cov
desulfurization reactor los ntawm cov txheej txheem ntau lawm. Hloov cov reactor nrog cua kom txog thaum cov pa oxygen concentration> 20% tau txais. Qhib lub reactor thiab unload lub adsorbent.
(3) Cov cuab yeej tu (overhaul)
Ua tib zoo saib cov txheej txheem raws li qhia saum toj no tshwj tsis yog tias lub siab yuav tsum qis dua 0.5MPa / 10min thiab temp.
txo qis lawm.
Lub unloaded adsorbent yuav tsum muab cia rau hauv nyias txheej. Txheeb xyuas cov qauv coj los ntawm txhua txheej los txiav txim
raws li txoj cai thiab kev pab lub neej ntawm lub adsorbent.
8.Kev thauj mus los thiab khaws cia
(1) Cov khoom adsorbent tau ntim rau hauv cov yas los yog hlau phom nrog cov yas hauv ob sab phlu kom tsis txhob ya raws thiab tshuaj
kev kis kab mob.
(2) Kev sib tsoo, kev sib tsoo thiab kev vibration hnyav yuav tsum tau zam thaum lub sijhawm thauj mus los los tiv thaiv pulverization ntawm
adsorbent.
(3) Cov khoom adsorbent yuav tsum raug tiv thaiv los ntawm kev sib cuag nrog cov tshuaj thaum thauj thiab khaws cia.
(4) Cov khoom tuaj yeem khaws cia rau 3-5 xyoos yam tsis muaj kev puas tsuaj ntawm nws cov khoom yog tias tsim nyog kaw.
Yog xav paub ntxiv txog peb cov khoom, thov tsis txhob yig tiv tauj kuv.
