Kurudziro yetekinoroji yemaitiro uye tsananguro yefekitori yekugadzira hydrogen yegesi yechisikigo (1)
1) Dhayagiramu yekutanga yekufamba kwemaitiro kugadzirwa kwehydrogen gasi rechisikigo
Cherechedza: Bhokisi rine madotsi ndiro muganhu we kugadzirwa kwehydrogen mudziyo, uye mutengesi ndiye ane basa rekutarisa nzvimbo iri mubhokisi rine madotsi.
2) Nheyo yeMaitiro
Yakasungirirwa pa skid kugadzirwa kwehydrogen gasi rechisikigo Zvishandiso zvinosanganisira matanho mashanu makuru ekuita: kumanikidzwa kwegasi rechisikigo, kubviswa kwesulfur mumafuta egasi rechisikigo, kugadziriswa kwemhepo inopfungaira mumhepo, kushandurwa kweCO2, uye kuparadzaniswa nekucheneswa kwehydrogen.
1) Kubvisa sulfur muzvinhu zvisina kugadzirwa
Gasi rechisikigo risina kubikwa rinopiswa kusvika 320-380℃ muchikamu che convection che reformer uye robva rapfuura nemu manganese oxide ne zinc oxide desulfurizers kubvisa organic sulfur ne H2.2S mugasi risina kubikwa ku pasi pe 0.1ppm kuti isangane nezvinodiwa nesarufa zvemuchina unogadzirisa steam. Maitiro makuru ndeaya anotevera:
H2S +ZnO→ ZnS + H2ZVINO
2) Kugadzirisa mhute yegesi rechisikigo: Mushure mekunge sarufa yegesi rechisikigo yabviswa kusvika pasi pe0.1 PPm, inosanganiswa nemhute yekushanda nechiyero che3.2 kusvika 3.5, uye inopinda mu coil yekupisa yegesi yakasanganiswa kuti ipfungaidzwe zvakanyanya kusvika 550 kusvika 600 °C isati yapinda muchubhu yekugadzirisa. Muchikamu che catalyst, methane inosangana nemhute yemvura kuti igadzire H2 uye CO, uye CO inoramba ichisangana nemhepo inopisa kuti igadzire CO22. Kupisa kunodiwa pakugadzirisa methane kunowanikwa nekupiswa kwegasi rakasanganiswa nemafuta. Kana paine nickel catalyst, maitiro ayo makuru ndeaya anotevera:
CH4 +H2O (mhepo) = CO +3H2 -49200Kcal/Kmol (maitiro ekuchinja)
CO+H2O (mhepo) = CO2 +H2+9840Kcal/Kmol (maitiro ekushandura)
Kutsemuka kwemaitiro e alkanes akakwirira (400 ～ 600 ℃)
CnH2n + 2nH2O (mhepo) =(2n+1) H2 + nCO
