Isopropanolke sehlapolli se sebelisoang haholo indastering, 'me thepa ea sona e tala e nkiloe haholo-holo ho mafura a lintho tsa khale. Lisebelisoa tse tala tse tloaelehileng haholo ke n-butane le ethylene, tse nkiloeng ho oli e tala. Ho phaella moo, isopropanol e ka boela ea etsoa ho tloha propylene, sehlahisoa se bohareng sa ethylene.

Mokelikeli oa isopropanol

 

Ts'ebetso ea tlhahiso ea isopropanol e rarahane, 'me lisebelisoa tse tala li hloka ho etsa letoto la liphetoho tsa lik'hemik'hale le mehato ea ho hloekisa ho fumana sehlahisoa se lakatsehang. Ka kakaretso, mokhoa oa tlhahiso o kenyelletsa dehydrogenation, oxidation, hydrogenation, karohano le tlhoekiso, joalo-joalo.

 

Ntlha ea pele, n-butane kapa ethylene e dehydrogenated ho fumana propylene. Ebe, propylene e oxidized ho fumana acetone. Joale acetone e hydrogenated ho fumana isopropanol. Qetellong, isopropanol e hloka ho etsa mehato ea ho arohana le ho hloekisa ho fumana sehlahisoa se phahameng sa bohloeki.

 

Ho feta moo, isopropanol e ka boela ea etsoa ho tsoa linthong tse ling tse tala, tse kang tsoekere le biomass. Leha ho le joalo, lisebelisoa tsena tse tala ha li sebelisoe haholo ka lebaka la lihlahisoa tsa tsona tse tlaase le theko e phahameng.

 

Lisebelisoa tse tala bakeng sa tlhahiso ea isopropanol haholo-holo li tsoa ho mafura a mafura, a sa jeng feela lisebelisoa tse sa tsosolosoeng empa hape a baka mathata a tikoloho. Ka hona, hoa hlokahala ho hlahisa lisebelisoa tse ncha le mekhoa ea tlhahiso ho fokotsa tšebeliso ea mafura a mafura le tšilafalo ea tikoloho. Hona joale, bafuputsi ba bang ba se ba qalile ho hlahloba tšebeliso ea lisebelisoa tse tsosolositsoeng (biomass) e le lisebelisoa tse tala bakeng sa tlhahiso ea isopropanol, e ka fanang ka litsela tse ncha bakeng sa tsoelo-pele e tsitsitseng ea indasteri ea isopropanol.
