Sehlohleletši sa Methanation

 

CAS-KR-J01-K methanation catalyst ke mohuta o mofsa wa thaethaniamo - aluminiamo - sewelo lefase - nikele sešušumeletši seo se loketšego yuniti ya methanation, go tloša mahloriso a tlase a khaponetaeoksaete le khaponetaeoksaete go tšwa go khase ya furu yeo e humilego ka hydrogen le go e fetolela go ba khase ye e sa šomego ya methane le meetse ao a tlošwago gabonolo, bjalo bjalo go fihlelela morero wa go hlwekiša khase, sešušumeletši se na le dithoto tše di kgethegilego tša go swana le maatla a magolo, bophagamo bja pore bjo bo phagamego, mošomo wo mogolo le go rwala le go fološa gabonolo, go molaleng gore se dira gabotse kudu go feta sešušumeletši se sengwe se se swanago ka fase ga kgatelelo ye kgolo le lebelo le legolo la sebaka.

Karabelo ya methanation ke karabelo ya exothermic kudu, tekano ya karabelo ke ye e latelago:

CO + 3H₂→ CH₄+ H₂O △H=-206.2KJ / mol

CO₂ + 4H₂→ CH₄+ 2H₂O △H=-165.0KJ / mol

Mošomo wo mogolo wa tshepedišo ya methanation ke go fetolela CO le CO2(tšeo di nago le mpholo go dihlohleletši tša tshepedišo ye e latelago) go tšwa motswakong go ba methane, e le gore go fihlelwe morero wa go hlwekiša hydrogen, go kaonafatša boleng bja khase ya khalori ya setšweletšwa le go fokotša tšhilafalo ya tikologo, Ka mohlala, ka intastering ya tswako ya ammonia, methanation e šomišwa go fokotša mahloriso a CO le CO2 ka fase ga 10ppm le go thibela sešušumeletši sa tšhipi go tsenywa mpholo. go tlaleletša, methanation e šomišwa gape bakeng sa go hlwekiša le go hlwekiša khase ya tlhago.

 

Tšhate ya go ela ya methanation

 

 

1) dinyakwa tša diteng tša S ka gare ga khase ya furu: Ka fase goba go lekana le 0.1PPm

2) dinyakwa tša Cl^-diteng ka gare ga khase ya furu: Ka fase goba go lekana le 0.03PPm

3) dinyakwa tša phepo khase import bophahamo ba modumo ya CO + CO₂< 0.7%

4) Go bohlokwa kudu go boloka themperetšha ye e tlwaelegilego ya go šoma: Thempheretšha ye e feteletšego ya CO2 ya maemo a godimo e tla hlola karabelo ya go bea khapone. Thempheretšha ya go feta - yeo e hlolwago ke go tsepama ga CO mo go phagamego mo lefelong la go tsena e dira gore sešušumeletši se se šome, kudukudu se bopa carbonyl ya nikele. thempereichara tlhahiso ke ke laoloa tlaase haholo, tlaase mocheso khase conduction ke sebaki ka sehloohong sa methanation catalyst deactivation.
