Kaupapa
Ko te reti whakawātea irahiko (desulfurization) o te tātari ngota, e kiia ana hoki ko te reti whakamātao irahiko, he taputapu matua i roto i te purenga hau māori, i te whakatikatika hau māori rānei. Ko te tatari ngota he tioata aluminosilicate whakarewa kawakore me te hanganga anga me te hanganga microporous ōrite. Ina haere te hau whāngai kei roto he wai iti i roto i te moenga tatari ngota i te pāmahana rūma, ka mimitihia te wai iti me te mercaptan, ka whakaitihia te wai me te ihirangi mercaptan i roto i te hau whāngai, ka tutuki ai te kaupapa o te maroke me te whakawātea. Ko te tukanga adsorption o te tatari ngota ko te condensation capillary me te adsorption tinana i puta mai i te kaha van der Waals. Mai i te whārite Kelvin, ka kitea ka ngoikore te condensation capillary me te pikinga o te pāmahana, ko te adsorption tinana he tukanga exothermic, ā, ka ngoikore te adsorption me te pikinga o te pāmahana me te pikinga o te pēhanga; nō reira, ko te tukanga adsorption o te tatari ngota ka mahia i te pāmahana iti me te pēhanga teitei, ko te whakahoutanga desorption ka mahia i te pāmahana teitei me te pēhanga iti. I raro i te mahi a te hau whakaora pāmahana teitei, pēhanga ma, me te pēhanga iti, ka tukuna e te adsorbent tātari ngota te adsorbate i roto i te micropore ki roto i te rere o te hau whakaora kia tae ra ano te nui o te adsorbate i roto i te adsorbent ki te taumata tino iti, ā, ka taea te mimiti i te wai me te mercaptan mai i te hau whāngai, ka tutuki ai te tukanga whakaora me te hangarua o te tātari ngota.
Tukanga hangarau
Kei te whakaatuhia te rere o te tukanga o te reti whakakorenga whanariki hau māori (desulfurization) i roto i te hoahoa. E toru ngā tukanga pourewa e whakamahia ana e te waeine, kotahi te mimitinga pourewa, kotahi te whakaora pourewa, me tetahi te whakamatao pourewa. Whai muri i te tango i te wai warowaihā kua mau mā te wehewehe tātari hau whāngai, ka tomo te hau whāngai ki te pourewa whakakorenga whanariki tātari ngota. Ka mimitia te wai me te mercaptan i roto i te hau whāngai e te tātari ngota hei whakatutuki i te tukanga mimiti me te mimiti mercaptan. Ka tomo te hau parakore mai i te mimiti me te tango mercaptan ki te tātari puehu hau hua hei tango i te puehu tātari ngota, kātahi ka kaweake hei hau hua.
Me whakahou anō ngā tātari ngota i muri i te mimiti i tētahi nui o te wai me te mercaptan. Whai muri i te tātari i te puehu hau hua, ka tangohia tētahi wāhanga o te hau hua hei hau whakaora. Whai muri i te whakamahana i te hau ki te 300 ℃ e te oumu whakamahana, ka whakamahana mārire te pourewa ki te 272 ℃ mā te pourewa whakakorenga whanariki tātari ngota kua oti te tukanga mimiti mai i raro ki runga, kia taea ai te wehe i te wai me te mercaptan e mimiti ana ki runga i te tātari ngota, ka huri hei hau whakaora whai rawa hei whakaoti i te tukanga whakaora.
