Te Whakapakari Methanation

 

Ko te CAS-KR-J01-K methanation catalyst he momo hou o te titanium - konumohe - onge whenua - nickel catalyst e pai ana mo te wae methanation, ki te tango iti te kukū o te waro monoxide me te waro hauhā mai i te hauwai whangai hauwai me te huri hei whakakorikori hau mokowhiti o te mewaro, kia ngawari te tango i te wai. te kaha teitei, te rahi o te pore, te mahi nui me te ngawari ki te uta me te wetewete, he pai ake te mahi i etahi atu whakakorikori rite i raro i te pehanga teitei me te tere o te waahi.

1) te iti o te waro haukura i roto i te hau puta.

2) iti me te pumau te heke o te pehanga na te kaha nui me te hanganga porowhita

3) pai te pūmautanga waiariki

4)ngawari mo te whakahohe me te timata- ake

5)he kaha ki te aukati -paratanga o waho

6) mahi teitei me te whiriwhiri

Te tere o te waahi mahi	Iti iho i te rite ranei ki te 10000h-1

 

 

Ko te tauhohenga methanation he tauhohenga exothermic tino, ko te wharite tauhohenga e whai ake nei:

CO + 3H₂→ CH₄+ H₂O △H =－206.2KJ/mol

CO₂ + 4H₂→ CH₄+ 2H₂O △H =－165.0KJ/mol

Ko te mahi matua o te tukanga methanation ko te huri i te CO me te CO2(he paitini ki nga whakakorikori tukanga e whai ake nei) mai i te ranunga ki te methane, kia tutuki ai te kaupapa o te pure i te hauwai, te whakapai ake i te uara calorific hau o te hua me te whakaiti i te parahanga o te taiao, Hei tauira, i roto i te ahumahi whakahiato haukini, ka whakamahia te methanation ki te whakaiti i te CO iisoron catalyst ki raro i te CO me te CO10ppm. i tua atu, ka whakamahia ano te methanation mo te purenga me te horoi o te hau maori.

 

Tutohi rere methation

 

 

1) nga whakaritenga mo te ihirangi o te S i roto i te hau whangai: Iti iho i te rite ranei ki te 0.1PPm

2) nga whakaritenga mo te Cl^-ihirangi i roto i te hau whangai: Iti iho i te rite ranei ki te 0.03PPm

3) nga whakaritenga mo te kohinga hau kawemai o CO + CO₂< 0.7%

4) He mea tino nui ki te pupuri i te pāmahana whakahaere noa: Ko te overtemperature o te kukū tiketike CO2 ka meinga te tauhohenga waro deposition. I runga i te -mahana na te nui o te CO kukū ki te kokoru ka wetewete te whakakorikori, te nuinga ka hanga nickel carbonyl. e kore e taea te whakahaere i te pāmahana whakangao kia iti rawa, ko te kawe hau wera iti te take matua o te whakakorenga whakakorikori methanation.
