Methanation Catalyst

 

CAS-KR{1}}J01-K methanation catalyst luhlobo olutsha lwe-titanium - aluminiyam - umhlaba onqabileyo-nickel catalyst elungele iyunithi ye-methanation, ukususa uxinaniso oluphantsi lwekharbon monoxide kunye necarbon dioxide kwigesi ye-hydrogen etyebileyo kwaye iyiguqulele ekubeni yi-methane isusa igesi yegesi yokutya kunye ne-methane ukuze iphumeze injongo yokunciphisa amanzi. igesi, i-catalyst ineempawu ezikhethekileyo ezifana namandla aphezulu, umthamo ophezulu we-pore, umsebenzi ophezulu kunye nokulayisha lula kunye nokukhulula, ngokucacileyo yenza ngcono kakhulu kunezinye i-catalyst efanayo phantsi koxinzelelo oluphezulu kunye nesantya esiphezulu sendawo.

I-methanation reaction yi-exothermic reaction, i-reaction equation imi ngolu hlobo lulandelayo:

CO + 3H₂→ CH₄+ H₂O △H =－206.2KJ/mol

CO₂ + 4H₂→ CH₄+ 2H₂O △H =－165.0KJ/mol

Umsebenzi oyintloko wenkqubo ye-methanation kukuguqula i-CO kunye ne-CO2 (eyityhefu kwii-catalysts zenkqubo elandelayo) ukusuka kumxube kwi-methane, ukuze kuphunyezwe injongo yokucoca i-hydrogen, ukuphucula ixabiso le-calorific yegesi yemveliso kunye nokunciphisa ukungcola kokusingqongileyo, Ngokomzekelo, kwi-industry ye-ammonia synthesis, i-methanation isetyenziselwa ukunciphisa i-iron concentration kunye ne-CO1 ye-iron isetyenziselwa ukunciphisa i-iron2pp kunye ne-CO1. Ukongeza, i-methanation ikwasetyenziselwa ukucocwa kunye nokucoca igesi yendalo.

 

Itshati yokuqukuqela kweMethanation

 

 

1) iimfuno zomxholo we-S kwigesi yokutya: Ngaphantsi okanye ilingana ne-0.1PPm

2) iimfuno zeCl^-umxholo kwigesi yokutya: Ngaphantsi okanye ilingana ne-0.03PPm

3) iimfuno zegesi yokutya umthamo wokungenisa weCO+CO₂< 0.7%

I-4) Kubaluleke kakhulu ukugcina ubushushu obuqhelekileyo bokusebenza: Ukushisa okuphezulu koxinzelelo lwe-CO2 kuya kubangela ukusabela kwe-carbon deposition. Ngaphezulu{3}}ubushushu obubangelwa kuxinzelelo lweCO ephezulu kwindawo yokungena yenza i-catalyst ingasebenzi, ikakhulu yenza i-nickel carbonyl. iqondo lobushushu imveliso ayikwazi ukulawulwa phantsi kakhulu, iqondo lobushushu eliphantsi conduction igesi ngoyena nobangela uphambili methanation catalyst deactivation.
