Haufinyane tjena, ts'ebetso e ncha ea oxidation e tobileng ea propylene oxide ka hydrogen peroxide betheng ea mokelikeli-solid circulating fluidized (FHPPO) e fetisitse tlhahlobo e hlophisitsoeng ke Federation ea China Petroleum le Chemical Industry Federation.Komiti ea tlhahlobo, e etelletsoeng pele ke Peng Xiaojun, setsebi sa thuto ea Sechaena Academy of Sciences, e lumetse ka ntsoe-leng hore theknoloji e nchafalitsoe haholo, e na le litebello tse ntle tsa tšebeliso, ’me e se e fihlile boemong bo ka sehloohong ba machaba, ’me ea etsa tlhahiso ea ho potlakisa khaho ea lisebelisoa tsa lipontšo.
Morero ona o entsoe ke sehlopha sa mofuputsi Huang Jiahui le moenjiniere e moholo Liu Yingchun Setsing sa Dalian sa Chemical Physics, Setsi sa Setsi sa Mahlale sa China, ka tšebelisano le Tianjin Dagu Chemical Co., LTD.Ho fapana le ts'ebetso e tobileng ea oxidation ea propylene oxide ka hydrogen peroxide (HPPO), FHPPO e ile ea sebelisa mokelikeli o tiileng o potolohang oa bethe ho hlahisa propylene oxide, e ileng ea bula tšimo e ncha ea ts'ebeliso ea indasteri ea mokelikeli o tiileng o potolohang bethe. .Ts'ebetso ena e na le litšobotsi tsa khabone e tala le e tlase, polokeho e phahameng le moruo o motle, 'me lintlha tsa bohlokoa tsa tekheniki li molemo ho feta ts'ebetso e teng.FHPPO e sebelisa metsi-solid circulating fluidized bed reaction-regeneration system ho e-na le setso sa tubular fixed-bed reactor ho matlafatsa mocheso le sekhahla sa phetisetso ea boima ba propylene liquid phase epoxidation reaction process le ho ntlafatsa katleho ea tlhahiso ea propylene oxide.The catalyst e ka lula e sebelisoa hape le ho nkeloa sebaka inthaneteng, e le hore karabelo ea epoxidation le nchafatso ea catalyst li hokahane haholo.
Morero o ile oa qalisoa ka 2019, 'me setsi sa liteko sa lithane tse 100 se ile sa kenngoa ts'ebetsong ka 2021. Ho tloha ka la 8 Pherekhong ho isa ho la 10 Pherekhong 2022, sehlopha sa litsebi se hlophisitsoeng ke Petrochemical Federation se ile sa etsa tlhahlobo e tsoelang pele ea lihora tse 72 le ho lekanya setsi sa liteko. .Liphetho tsa ho lekanya li bonts'a hore sekhahla sa phetoho ea hydrogen peroxide sesebelisoa ke 99.7%, khetho ea propylene oxide ke 98.2%, tekanyo e sebetsang ea hydrogen peroxide ke 99.9%, 'me bohloeki ba sehlahisoa ke 99.95%.
Theknoloji e ncha e lebelletsoe ho ntlafatsa boemo ba tekheniki ea tlhahiso ea propylene oxide haeba e ka etsoa indasteri kapele kamoo ho ka khonehang, lik'hamphani tse ling tsa propylene oxide li boletse.
Ho ea ka moqolotsi oa litaba, ka ts'ebetso e tsoelang pele ea leano la "double carbon", indasteri ea propylene oxide e tobane le phetoho le ntlafatso, 'me mokhoa oa co-oxidation propylene oxide route le HPPO butle-butle li fetohile tse ka sehloohong tsa nts'etsopele ea indasteri.HPPO e na le litšobotsi tsa tšilafalo e fokolang le maemo a karabelo a bobebe.Lilemong tsa morao tjena, merero e mecha ea HPPO propylene oxide e ntse e eketseha lefatšeng, 'me likhoebo tse ngata tsa malapeng le litsi tsa lipatlisiso tsa saense li theohile butle-butle ka theknoloji ea HPPO core process.
Ka 2014, Sinopec Shi Academy le Changling Refining & Chemical li ile tsa hlahisa lisebelisoa tsa pele tsa lithane tse 100,000 / selemo tsa lisebelisoa tsa indasteri tsa HPPO Chaena li sebelisa theknoloji e ikemetseng, ho etsa hore Chaena e be naha ea boraro e nang le lisebelisoa tse feletseng tsa theknoloji ea HPPO lefatšeng.Ka 2018, theknoloji e ile ea tsejoa e le e tsoetseng pele ea machaba, 'me theknoloji e susumetsang le tšebeliso ea thepa e ne e le boemong bo ka sehloohong ba machaba.
Ka la 12 September selemong sena, Yida Stock e phatlalalitse hore propylene oxide ea projeke ea 150,000 / selemo ea Taixing Yida e amohetse theknoloji ea ts'ebetso ea HPPO e ikemetseng e entsoeng ke Yida, 'me ka mor'a tlhahiso ea liteko le ts'ebetso, e se e hlahisitse lihlahisoa tsa sehlopha se setle ka ho fetisisa.
