Tlhahiso ea hydrogen ho tsoa khase ea tlhaho ke ho etsa lik'hemik'hale tsa khase ea tlhaho e hatelletsoeng le e senyehileng le mouoane ka mokelikeli o khethehileng o tlatsitsoeng ka mokelikeli le ho hlahisa khase e nchafatsang ka H₂, CO₂ le CO, ho fetolela CO ka likhase tse nchafatsang ho CO₂ ebe o ntša. e tšoanelehang H₂ ho tsoa likhase tse nchafatsang ka khatello ea "swing adsorption" (PSA).
Moralo oa Setsi sa Tlhahiso ea Hydrogen le khetho ea lisebelisoa li hlahisoa ho tsoa lithutong tse pharalletseng tsa boenjiniere tsa TCWY le litlhahlobo tsa barekisi, ka ho ntlafatsa haholo tse latelang:
1. Tšireletseho le boiketlo ba ts'ebetso
2. Ho tšepahala
3. Phano ea thepa e khutšoanyane
4. Mosebetsi o fokolang oa tšimo
5. Chelete ea tlhōlisano le litšenyehelo tsa ho sebetsa
(1) Ho Felisoa ha Khase ea Tlhaho
Ka mocheso o itseng le khatello, ka khase ea phepelo ka oxidation ea manganese le zinc oxide adsorbent, sebabole se felletseng ka khase ea phepelo e tla tima ka tlase ho 0.2ppm ka tlase ho fihlela litlhoko tsa li-catalysts bakeng sa phetoho ea mouoane.
Maikutlo a mantlha ke:
| COS+MnO |
| MnS+H2O |
| H2S+ZnO |
(2) NG Steam Reforming
Mokhoa oa ho fetola mouoane o sebelisa mouoane oa metsi e le oxidant, 'me ka nickel catalyst, hydrocarbons e tla fetoloa hore e be khase e tala bakeng sa ho hlahisa khase ea hydrogen. Ts'ebetso ena ke endothermic process e hlokang phepelo ea mocheso ho tsoa karolong ea radiation ea Sebopi.
Karabelo e kholo boteng ba li-catalyst tsa nickel ke tse latelang:
| CnHm+nH2O = nCO+(n+m/2)H2 |
| CO+H2O = CO2+H2 △H°298= – 41KJ/mol |
| CO+3H2 = CH4+H2O △H°298= – 206KJ/mol |
(3) Tlhoekiso ea PSA
Joalo ka ts'ebetso ea yuniti ea lik'hemik'hale, theknoloji ea karohano ea khase ea PSA e ntse e tsoela pele ka potlako ho ba taeo e ikemetseng, 'me e sebelisoa ka bongata libakeng tsa petrochemical, lik'hemik'hale, tšepe, lisebelisoa tsa elektroniki, ts'ireletso ea naha, meriana, indasteri e bobebe, temo le ts'ireletso ea tikoloho. liindasteri, joalo-joalo. Hona joale, PSA e fetohile mokhoa o ka sehloohong oa H2karohano eo e 'nileng ea sebelisoa ka katleho bakeng sa tlhoekiso le karohano ea carbon dioxide, carbon monoxide, nitrogen, oxygen, methane le likhase tse ling tsa indasteri.
Phuputso e fumane hore lisebelisoa tse ling tse tiileng tse nang le sebopeho se setle sa porous li ka monya limolek'hule tsa mokelikeli, 'me lintho tse joalo tse monyang li bitsoa monyetla. Ha limolek'hule tsa mokelikeli li kopana le li-adsorbents tse tiileng, adsorption e etsahala hang-hang. The adsorption e etsa hore ho be le mahloriso a fapaneng a limolek'hule tse monyelitsoeng mokelikeli le holim'a metsi. 'Me limolek'hule tse adsorbed ka monyeng li tla ruisa holim'a eona. Joalo ka tloaelo, limolek'hule tse fapaneng li tla bonts'a litšobotsi tse fapaneng ha li nkuoa ke li-adsorbents. Hape maemo a kantle joalo ka mocheso oa mokelikeli le khatello ea maikutlo (khatello) a tla ama sena ka kotloloho. Ka hona, feela ka lebaka la mofuta ona oa litšobotsi tse fapaneng, ka phetoho ea mocheso kapa khatello, re ka finyella karohano le ho hloekisa motsoako.
Bakeng sa semela sena, li-adsorbent tse fapaneng li tlatsitsoe betheng ea adsorption. Ha khase e nchafatsang (motsoako oa khase) e kenella ka har'a kholomo ea adsorption (bethe ea adsorption) tlasa khatello e itseng, ka lebaka la litšobotsi tse fapaneng tsa adsorption tsa H.2, CO, CH2, CO2, joalo-joalo the CO, CH2le CO2li hlahisoa ke li-adsorbents, ha H2e tla phalla ho tsoa ka holim'a bethe ho fumana sehlahisoa se tšoanelehang sa hydrogen.
