Inkqubo yokuvelisa i-N-hexane
Uninzi lwemveliso ye-hexane yangaphandle isebenzisa iinkqubo ze-molecular sieve adsorption, ezifana ne-Richfielcd (i-Richfield) kunye ne-Watson (i-Watson) e-United States, kusetyenziswa i-raffinate ehlaziyiweyo njengemathiriyeli ekrwada, ngokuphinda kusetyenziswe iibhedi ezimbini nangaphezulu ukuze zifakwe kwi-adsorption. Cofa i-desorption ukuvelisa i-n-hexane.
Uninzi lwabavelisi be-hexane basekhaya basebenzisa inkqubo ye-hydrogenation distillation, eyahlulahlulwe yaba ziindidi ezimbini:

Okokuqala, i-hydrogenation emva koko ukulungiswa.

Ikwabizwa ngokuba yi-pre-hydrogenation, imathiriyeli ekrwada ifudunyezwa ngokutshintshiselana kobushushu, ifikelela kwiqondo lobushushu lokuphendula, ingena kwi-reactor ye-hydrogenation, i-desulfurization kunye ne-deomatization reaction phantsi kwesenzo se-catalyst, i-oyile enyibilikayo kunye nomxube we-hydrogen ungene kwitanki yokwahlula. , ukubuyiswa kwe-hydrogen, ioli enyibilikayo kwinqaba yokwahlula Sika kwiimveliso ezigqityiweyo. Ngokuqhelekileyo, emva kwe-hydrogenation yezinto eziluhlaza, isahlulwe kwaye inqunywe ibe yi-n-hexane, kunye nezinye iintlobo ezahlukeneyo zeoli ye-solvent. Inzuzo kukuba zonke iimathiriyeli ezikrwada zi-deomatized kwaye ziphelile, zisebenzisa ngokupheleleyo imveliso nganye. Ukungalungi kukuba utyalo-mali lukhulu kwaye ukusetyenziswa kwezinto eziphathekayo kuphezulu.

Okwesibini, ukulungiswa emva koko i-hydrogenation.

Ekwabizwa ngokuba yi-post-hydrogenation, kwimeko ye-n-hexane, izinto eziluhlaza ziqala ukunqunyulwa kwi-hexane ekrwada yoluhlu lwe-distillation ye-66-69, ukucoceka kwe-hexane ekrwada kuphuculwe kakhulu, kwaye ekubeni iqela le-phenyl Okuqulathwe kwi-n-hexane, i-hexane kwi-hexane ekrwada Umxholo nawo uye wanda kakhulu, kwaye emva koko uphantsi kwe-hydrodebenzene desulfurization ukuvelisa umgangatho ophezulu we-n-hexane. Inzuzo kukuba utyalo-mali luncinci kwaye ukusetyenziswa kwezinto eziphathekayo kuncinci. Ukungalungi kukuba inxalenye ye-unhydrogenated ayisetyenziswanga ngokufanelekileyo.
