Karabelo ea methanation ke karabelo e makatsang haholo, karabelo equation ke e latelang:

CO + 3H₂→ CH₄+ H₂O △H =－206.2KJ/mol

CO₂ + 4H₂→ CH₄+ 2H₂O △H =－165.0KJ/mol

Mosebetsi o ka sehloohong oa ts'ebetso ea methanation ke ho fetola CO le CO2 (tse nang le chefo ho li-catalysts tse latelang) ho tloha motsoako ho kena methane, e le ho finyella morero oa ho hloekisa hydrogen, ho ntlafatsa boleng ba khalori ea khase ea sehlahisoa le ho fokotsa tšilafalo ea tikoloho, Ka mohlala, indastering ea ammonia synthesis, methanation e sebelisoa ho fokotsa chefo ea CO1 le CO2pps ka tlaase ho tšepe. Ho feta moo, methanation e boetse e sebelisetsoa ho hloekisa le ho hloekisa khase ea tlhaho.

 

Chate ea phallo ea methanation

 

 

1) litlhoko tsa litaba tsa S ka khase ea phepelo: Ka tlase ho kapa ho lekana le 0.1PPm

2) litlhoko tsa Cl^-litaba tse ka har'a khase ea phepelo: Ka tlase ho kapa ho lekana le 0.03PPm

3) litlhoko tsa boleng ba khase ea phepelo ea CO + CO₂< 0.7%

4) Ho bohlokoa haholo ho boloka mocheso o tloaelehileng oa ts'ebetso: Mocheso o feteletseng oa khatello e phahameng ea CO2 o tla baka karabelo ea deposition ea carbon. Ho feta-thempereichara e bakiloeng ke CO e ngata ka har'a seketsoana e tima sekontiri, haholo-holo ho etsa nickel carbonyl. mocheso oa tlhahiso o ke ke oa laoloa o le tlase haholo, mocheso o tlaase oa khase ke sesosa se ka sehloohong sa ho thibela methanation catalyst deactivation.
