  • Sebaka sa bokhoni: 10 ~ 50000Nm3 / h
  • H2bohloeki: Ka tloaelo 99.999% ka vol.(boikhethelo 99.9999% ka palo.)
  • H2khatello ea phepelo: Ka tloaelo 15 bar (g)
  • Tshebetso: Ka ho iketsa, PLC e laoloa
  • Lisebelisoa: Bakeng sa tlhahiso ea 1,000 Nm³/h H2Ho tsoa methanol, lisebelisoa tse latelang lia hlokahala:
  • 500 kg / h methanol
  • 320 kg / h metsi a demineralized
  • 110 kW matla a motlakase
  • 21T/h metsi a pholileng

Tshebetso

Methanol Cracking Hydrogen Production Technology e sebelisa methanol le metsi joalo ka lisebelisoa tse tala, e fetola methanol hore e be khase e tsoakiloeng ka catalyst le ho hloekisa haedrojene ka khatello ea "press swing adsorption" (PSA) tlasa mocheso le khatello e itseng.

1. Ho kopanya ho phahameng: sesebelisoa se seholo se ka tlase ho 2000Nm3/h e ka thellisoa mme ea fanoa ka kakaretso.

2. Mefuta e fapaneng ea mekhoa ea ho futhumatsa: ho futhumatsa ho futhumatsang oxidation;Ho futhumatsa ho potoloha ha khase ea flue;Fuel mocheso conduction oli sebōpi futhumatsang;Motlakase o futhumatsang mocheso o tsamaisang oli o futhumatsang.

3. Tšebeliso e tlaase ea methanol: bonyane tšebeliso ea methanol ea 1Nm3haedrojene e netefalitsoe ho ba <0.5kg.Ts'ebetso ea 'nete ke 0.495kg.

4. Ho tsosolosoa ha maemo a phahameng a matla a mocheso: ho eketsa tšebeliso ea matla a mocheso le ho fokotsa phepelo ea mocheso ka 2%;

(1) Methanol Cracking

Kopanya methanol le metsi ka tekanyo e itseng, khatello, mocheso, mouoane le ho chesa motsoako oa motsoako ho fihlela mocheso o itseng le khatello, ebe ka pel'a catalyst, methanol cracking reaction le CO shifting reaction li etsa ka nako e le 'ngoe,' me li hlahise motsoako oa khase le H2, CO2le palo e nyane ea CO e setseng.

Methanol cracking ke karabelo e rarahaneng ea likarolo tse ngata tse nang le khase e 'maloa le lik'hemik'hale tse tiileng

Maikutlo a bohlokoa:

CH3OHjtCO + 2H2- 90.7kJ / mol

CO + H2OjtCO2+ H2+ 41.2kJ/mol

Kakaretso ea maikutlo:

CH3OH + H2OjtCO2+ 3H2- 49.5kJ / mol

 

Ts'ebetso eohle ke ts'ebetso ea endothermic.Mocheso o hlokahalang bakeng sa karabelo o fanoa ka ho potoloha ha oli ea mocheso oa mocheso.

Ho boloka matla a mocheso, khase e tsoakiloeng e hlahisoang ka har'a reactor e etsa phapanyetsano ea mocheso le mokelikeli oa motsoako oa lintho tse bonahalang, ebe oa kokoana, ebe o hlatsuoa tora ea tlhoekiso.Mokelikeli oa motsoako o tsoang ho condensation le mokhoa oa ho hlatsoa o aroloa tora ea tlhoekiso.Sebopeho sa mokelikeli ona oa motsoako ke haholo-holo metsi le methanol.E khutlisetsoa ka tanka ea thepa e tala hore e sebelisoe hape.Khase e hloahloa e ntan'o romelloa yuniti ea PSA.

(2) PSA-H2

Pressure Swing Adsorption (PSA) e ipapisitse le papatso ea 'mele ea limolek'hule tsa khase sebakeng se ka hare sa adsorbent e itseng (lintho tse thata tse porous).The adsorbent e bonolo ho adsorb likarolo tse phahameng tse belang 'me ho thata ho adsorb likarolo tse tlaase tse belang ka khatello e tšoanang.Palo ea adsorption e eketseha ka tlasa khatello e phahameng mme e fokotseha tlasa khatello e tlase.Ha khase ea phepelo e feta betheng ea adsorption tlas'a khatello e itseng, litšila tse belang haholo li khetholloa ka mokhoa o ikhethileng 'me haedrojene e belang e tlase e sa adsorbed habonolo ea tsoa.Ho aroloa ha hydrogen le likarolo tsa litšila hoa phethahala.

Ka mor'a ts'ebetso ea adsorption, adsorbent e senya litšila tse nkiloeng ha li fokotsa khatello e le hore li ka tsosolosoa ho adsorb le ho arola litšila hape.
