Methanation Catalyst

 

CAS-KR-J01-K methanation catalyst ndi mtundu watsopano wa titaniyamu - aluminiyamu - rare earth - nickel catalyst yomwe ili yoyenera methanation unit, kuchotsa mpweya wochepa wa carbon monoxide ndi carbon dioxide kuchokera ku hydrogen rich feed gas ndi kuwasintha kuti athetse ntchito yochotsa madzi a hydrogen, ndi kuwasandutsa kuti athetse ntchito yochotsa madzi. mpweya, chothandizira chimakhala ndi zinthu zapadera monga mphamvu yapamwamba, kuchuluka kwa pore, ntchito yapamwamba komanso kutsitsa kosavuta ndi kutsitsa, mwachiwonekere imachita bwino kwambiri kuposa chothandizira china chofanana pansi pa kuthamanga kwakukulu ndi kuthamanga kwapamwamba.

Kufotokozera (mm)	Φ4.5-5.5或Φ3.0-4.0
granular Mphamvu yolimbana ndi kukakamiza	Kuposa kapena kufanana ndi 140, Kuposa kapena kufanana ndi 120
Kuchulukana kwakukulu	0.9±0.03
Malo enieni (m2/g)	Kuposa kapena kufanana ndi 120

 

 

1) kutsika kwa carbon oxide mu mpweya wotuluka.

2) kutsika kotsika komanso kokhazikika kutsika chifukwa champhamvu komanso mawonekedwe ozungulira

3) kukhazikika kwabwino kwamafuta

4)zosavuta kuyambitsa ndikuyamba-mmwamba

5)kuthekera kwakukulu koletsa-kuipitsidwa kwakunja

6) ntchito yayikulu komanso kusankha

 

 

Kanthu	Parameter
zomwe zili mu S mu gasi wodyetsa	Zocheperapo kapena zofanana ndi 0.1PPm
Zomwe zili mu Cl mu mawonekedwe a gasi	Ochepera kapena ofanana ndi 0.03PPm
Kutentha koyambitsa:	210 digiri

Mkhalidwe wa ntchito:	0.5-32.0MPa
Kuthamanga kwa danga la ntchito	Zochepera kapena zofanana ndi 10000h-1

 

 

Methanation reaction ndi exothermic reaction, ma equation amayankha motere:

CO + 3H₂→ CH₄+ H₂O △H =－206.2KJ/mol

CO₂ + 4H₂→ CH₄+ 2H₂O △H =－165.0KJ/mol

Ntchito yaikulu ya ndondomeko methanation ndi kutembenuza CO ndi CO2 (omwe ndi poizoni kwa wotsatira ndondomeko chothandizira) kuchokera osakaniza mu methane, kuti akwaniritse cholinga kuyeretsa haidrojeni, kuwongolera mpweya mtengo wa calorific wa mankhwala ndi kuchepetsa kuipitsidwa kwa chilengedwe, Mwachitsanzo, mu makampani kaphatikizidwe ammonia, methanation ntchito kuchepetsa ndende CO1 ndi CO2pptam ndende poyimitsa chitsulo pansi pa CO1 ndi chitsulo. Kuphatikiza apo, methanation imagwiritsidwanso ntchito pakuyeretsa ndi kuyeretsa gasi.

1) Zofunikira za S mu gasi wodyetsa: Zochepera kapena zofanana ndi 0.1PPm

2) Zofunikira za Cl^-Zomwe zili mu gasi wodyetsa: Zochepera kapena zofanana ndi 0.03PPm

3) Zofunikira pakulowetsa mpweya wa CO + CO₂< 0.7%

4) Ndikofunikira kwambiri kukhalabe ndi kutentha kwanthawi zonse: Kutentha kopitilira muyeso kwa CO2 kumapangitsa kuti mpweya ukhalepo. Kutentha kopitirira-kumabwera chifukwa cha kuchuluka kwa CO pa malo olowera kumapangitsa chothandizira, makamaka kupanga faifi wa carbonyl. Kutentha kwapang'onopang'ono sikungathe kuyendetsedwa otsika kwambiri, kutsika kwamafuta kwamafuta otsika ndizomwe zimayambitsa kutsekedwa kwa methanation catalyst.
