Ukucubungula imfucuza yepulasitiki ibe yi-propane - ubuchwepheshe bekhulu lama-21
Udoti wePlastiki yikhanda elibuhlungu kunoma yiliphi izwe emhlabeni. Ezinye izifundazwe zishisa ama-polymers, kanti ezinye ziwaqoqa ezindaweni zokulahla. Kunamazwe anekhono lokugaywa kabusha, ngemuva kokuhlunga okuyinkimbinkimbi ngohlobo lwepulasitiki. Ithuluzi elihle lokucekela phansi imfucuza kwakuwubuchwepheshe be-polymer granulation ukuze kuqhutshekwe nokukhiqizwa komgwaqo. Izwe ngalinye linendlela yalo yokubuyisela udoti.
AbaseMelika bahlongoza ukuguqula isimo ngokugaywa kabusha kwepulasitiki. I-Massachusetts Institute of Technology yathola indlela eyingqayizivele. Ososayensi bahlongoza ukucekela phansi amapulasitiki besebenzisa ama-catalyst. Umphumela kufanele kube igesi ye-propane. Ngaphezu kwalokho, isivuno esiwusizo singama-80%. I-zeolite esekwe ku-cobalt isetshenziswa njenge-catalyst.
Ukucubungula imfucuza yepulasitiki ibe yi-propane - ubuchwepheshe bekhulu lama-21
Umbono uyathakazelisa. Okungenani iqiniso lokuthi ukukhiqizwa kwe-propane akudingekile ukuchitha isikhathi sokuhlunga. Ngaphezu kwalokho, ngenkathi yenkinga yamandla eYurophu, lokhu kuyindlela enhle yokukhokhela ukuntuleka kwegesi yemvelo. Isixazululo esinjalo somnotho sizovala imibuzo eminingana ngesikhathi esisodwa:
- Ukulahlwa kwemfucuza.
- Ikhono lokuqhubeka nokusebenzisa ipulasitiki eshibhile ekukhiqizeni ngaphandle kokulimaza imvelo.
- Ukonga ngokhuni. Ngempela, ngenxa yokuvinjelwa kwezikhwama zepulasitiki, amazwe amaningi ashintshele ephepheni.
- Ukuthola igesi ewusizo (propane) emkhakheni wezamandla.
Ngokumelene nesizinda sazo zonke lezi zinzuzo, kune-drawback eyodwa ebalulekile. I-Cobalt. Insimbi enamandla imbiwa emazweni angamashumi amabili nambili. Okusho ukuthi, kwezinye izifundazwe lapho kungambiwa khona, kuzoba nenani elithile. Ngokwemvelo, ngokombono wezomnotho, kuphakama imibuzo - indlela ephumelela ngayo indlela yokucubungula.
Uma kucatshangelwa iqiniso lokuthi kukhona amadiphozithi amakhulu e-cobalt e-Afrika, e-China, e-Australia, eCanada naseRussia, ukucutshungulwa kwepulasitiki ku-propane kuzoba nentshisekelo emazweni asohlwini. Okusele kuyodingeka ukubala imali engenayo nezindleko ukuze kutholwe ukuvumelana ngalolu daba.
