I-Hydrogen isetyenziswa ngokubanzi kwintsimbi, isinyithi, imboni yeekhemikhali, unyango, imboni yokukhanya, izinto zokwakha, i-electronics kunye nezinye iindawo. Itekhnoloji yokuguqula iMethanol ukuvelisa ihydrogen ineengenelo zotyalo-mali oluphantsi, akukho ngcoliseko, kwaye kulula ukusebenza. Isetyenziswe ngokubanzi kuzo zonke iintlobo zezityalo ze-hydrogen ezicocekileyo.
Xuba i-methanol kunye namanzi ngomlinganiselo othile, ucinezele, ubushushu, umphunga kwaye ugqithise umxube wezinto ezixutyiweyo ukuze ufikelele kubushushu obuthile kunye noxinzelelo, emva koko kukho i-catalyst, i-methanol cracking reaction kunye ne-CO shifting reaction yenza ngaxeshanye, kwaye uvelise umxube wegesi kunye ne-H2, i-CO2 kunye nexabiso elincinci le-CO eseleyo.
Yonke le nkqubo yinkqubo ye-endothermic. Ubushushu obufunekayo ekuphenduleni bunikezelwa ngokujikeleza kweoli yokushisa ukushisa.
Ukugcina amandla obushushu, umxube werhasi owenziwe kwi-reactor wenza utshintsho lobushushu ngolwelo oluxubeneyo, emva koko lujike, luhlanjwe kwinqaba yokucoca. Ulwelo oluxutywayo olusuka kwi-condensation kunye nenkqubo yokuhlamba luhlukaniswe kwinqaba yokucoca. Ukuqulunqwa kolulwelo oluxutyiweyo ikakhulu ngamanzi kunye nemethanol. Ibuyiselwa kwitanki yemathiriyeli ekrwada ukuze isetyenziswe kwakhona. Irhasi yokuqhekeka eqeqeshiweyo ke ithunyelwa kwiyunithi yePSA.
Iimpawu zobuGcisa
1. Ukuqina okuphezulu (i-modularization eqhelekileyo), ukubonakala okuthambileyo, ukuguquguquka okuphezulu kwindawo yokwakha: isixhobo esiphambili esingaphantsi kwe-2000Nm3/h inokutyibilika kwaye inikezelwe ngokupheleleyo.
2. Ukwahlukana kweendlela zokufudumeza: ukufudumala kwe-oxidation ye-catalytic; Ukufudumeza ngokuzifudumeza kwegesi ye-flue; Ukushisa kwe-fuel conduction oyile yokufudumeza iziko; Ukufudumeza kombane ukufudumeza ubushushu be-oyile.
3. Izinto eziphantsi kunye nokusetyenziswa kwamandla, ixabiso eliphantsi lokuvelisa: ubuncinane bokusetyenziswa kwe-methanol ye-1Nm3i-hydrogen iqinisekisiwe ukuba ingaphantsi kwe-0.5kg. Okwenziweyo yi-0.495kg.
4. Ukubuyiswa kwe-Hierarchical yamandla okushisa: ukwandisa ukusetyenziswa kwamandla okushisa kunye nokunciphisa ukunikezelwa kobushushu nge-2%;
5. Itekhnoloji evuthiweyo, ikhuselekile kwaye inokwethenjelwa
6. Umthombo wemathiriyeli efumanekayo, uthutho olufanelekileyo kunye nokugcinwa
7. Inkqubo elula, i-automation ephezulu, kulula ukuyisebenzisa
8. Ayinabungozi kokusingqongileyo, ingenangcoliseko
Xuba i-methanol kunye namanzi ngomlinganiselo othile, ucinezele, ubushushu, umphunga kwaye ugqithise umxube wezinto ezixutyiweyo ukuze ufikelele kubushushu obuthile kunye noxinzelelo, emva koko kukho i-catalyst, i-methanol cracking reaction kunye ne-CO shifting reaction yenza ngaxeshanye, kwaye uvelise umxube wegesi kunye ne-H2, CO2kunye nemali encinci ye-CO eseleyo.
Ukuqhekeka kwe-Methanol yimpendulo entsonkothileyo ye-multicomponent kunye neegesi ezininzi kunye neekhemikhali eziqinileyo
Iimpendulo ezinkulu:
| CH3OH |
| CO + H2O |
Isishwankathelo sempendulo:
CH3OH + H2O CO2+ 3H2– 49.5kJ/mol |
Yonke le nkqubo yinkqubo ye-endothermic. Ubushushu obufunekayo ekuphenduleni bunikezelwa ngokujikeleza kweoli yokushisa ukushisa.
Ukugcina amandla obushushu, umxube werhasi owenziwe kwireactor wenza utshintsho lobushushu ngolwelo oluxubeneyo, emva koko luyajiya, luhlanjwe kwinqaba yokucoca. Ulwelo oluxutywayo olusuka kwi-condensation kunye nenkqubo yokuhlamba luhlukaniswe kwinqaba yokucoca. Ukuqulunqwa kolulwelo oluxutyiweyo ikakhulu ngamanzi kunye nemethanol. Ibuyiselwa kwitanki yemathiriyeli ekrwada ukuze isetyenziswe kwakhona. Irhasi yokuqhekeka eqeqeshiweyo ke ithunyelwa kwiyunithi yePSA.
I-Pressure Swing Adsorption (PSA) isekelwe kwi-adsorption ebonakalayo ye-molecule yegesi kwindawo yangaphakathi ye-adsorbent ethile (izinto eziqinileyo eziqinileyo). I-adsorbent ilula ukubhengeza amacandelo aphezulu abilisa kwaye kunzima ukubhengeza amacandelo aphantsi abilayo kuxinzelelo olufanayo. Isixa se-adsorption sonyuka ngaphantsi koxinzelelo oluphezulu kwaye siyancipha phantsi koxinzelelo oluphantsi. Xa irhasi yokutya idlula kwibhedi ye-adsorption phantsi koxinzelelo oluthile, ukungcola okuphezulu okubilisa ngokukhethayo kunye ne-hydrogen ebilisa kancinci engenakubhengezwa ngokulula iyaphuma. Ukwahlulwa kwe-hydrogen kunye neenxalenye zokungcola kuyenziwa.
Emva kwenkqubo ye-adsorption, i-adsorbent ikhupha ukungcola okufunxayo xa inciphisa uxinzelelo ukuze ihlaziywe kwi-adsorb kwaye ihlukanise ukungcola kwakhona.
