Propane dehydrogenation alternaria alternata propylene by-product hydrogen gasi, kana iyo ye-product hydrogen isina nzira dzekutengesa, inogona kungopisa semafuta emafuta, inokanganisa zvakananga hupfumi hwepropane dehydrogenation, kana ichienzaniswa neyakajeka hydrocarbon cracking, propane dehydrogenation (hydrogen burn) the mutengo we olefin wakakwira zvakanyanya kupfuura propane dehydrogenation process, zvigadzirwa zvikuru zvechiedza hydrocarbon cracking ye ethylene propylene, by-product hydrogen mafuta gasi musanganiswa wecarbon four Mixed carbon five, inogona kugadzirisa propane dehydrogenation pachayo pasina ethylene uye butene kuzvidemba, pyrolysis ye iyo-yakagadzirwa inogona zvakare kuona kukosha kwayo, panguva imwechete ine mukana wemutengo wakaderera, inogona kunge iri mumusika weiyo unregulated copolymerization uye kukanganisa copolymerization, kuwedzera kwehupfumi mumakore achangopfuura Iyo hydrogen indasitiri yemagetsi ine simba rakasimba rekutyaira. .Panguva imwecheteyo, nekuwedzera kwehuwandu hwematerminal application scenarios, chikamu chemusika chinodiwa chakawedzerawo zvishoma nezvishoma indasitiri yesimba rehydrogen kusvika padanho rakati, uye mazhinji emabhizinesi epamba propane dehydrogenation akatanga kuterera kana kurongeka. nzira dzavo dzekutengesa uye zvirongwa zvekushandisa zvehydrogen nechigadzirwa Muchiitiko ichi, propane dehydrogenation, ingave inotengeswa semaindasitiri hydrogen kana semafuta anodhura sero hydrogen kana kunyange yakakwirira yakachena hydrogen, ichapa kudzoka kwehupfumi uye nokudaro kuwedzera purofiti yemakambani epropane dehydrogenation. .Kana tichienzanisa, propane dehydrogenation tekinoroji ine maitiro mapfupi uye yakaderera kushandiswa Kuwanda kwegoho uye yakaderera mari yekudyara yeimwe seti yemidziyo.Kana ichigona kusanganiswa nemichina yekunatsa yakatenderedza kuti ipe haidrojeni yekunatsa uye kuwedzera mabhenefiti kuburikidza nekupanana kwezvakagadzirwa zvinhu, mukana wekupwanya wehydrocarbon wakajeka uri muchikamu chikuru chekudyara, zvigadzirwa zvakasiyana uye kugona kwakasimba kurwisa njodzi dzemusika.Hupfumi hwezviviri izvi zvinonyanya kuenderana ne ethylene uye Propylene mutengo: Iyo propane dehydrogenation nzira inodhura zvakanyanya kana ethylene nepropylene mitengo iri pedyo, uye mwenje wehydrocarbon yekupwanya nzira inodhura zvakanyanya kana ethylene mitengo yakakwira kupfuura propylene.

Propane dehydrogenation raw material single, inongoshandisa propane seyakagadzirwa, chigadzirwa chete propylene uye ne-chigadzirwa hydrogen, yakaderera kabhoni kuchengetedzwa kwezvakatipoteredza kwete chete, ichiri inogona kuderedza njodzi yezvimwe zvinhu, ichiri chitsva chiripo mune chikuru bhizinesi sarudzo yetekinoroji, ruzhinji rweChina kugadzirwa kwePDH mudziyo unoenderana nekudzika kwemvura mudziyo, indasitiri yekubatanidza maitiro zviri pachena, asi nekufamba kwenguva, nzvimbo yakadzika yeindasitiri cheni yekuvandudza nzvimbo yakamanikana, Kudzvanywa kwemusika kwakakura, mumusha we polypropylene kugadzirwa kwakapetwa kaviri mumakwikwi anotyisa emusika, ethylene propane dehydrogenation purojekiti yemakwikwi inofanirwa kuongororwazve.

Kuenzaniswa nepropane dehydrogenation, yakareruka hydrocarbon yekupaza maitiro ane akawanda akasiyana zvigadzirwa zvigadziriso uye yakasimba musika kukanganisa.Nekuenzanisa kutaura, hupfumi hwepropane dehydrogenation process inonyanya kuenderana nemusiyano wemutengo pakati pepropylene nepropane.Kana mutengo wemusika wepropylene uchichinja uye uchiderera, hupfumi hwepropane dehydrogenation process huchadzikiswa zvakanyanya.

Kune indasitiri yepolypropylene, propane sosi inoverengera chikamu chidiki, kunyangwe yakawedzera kubva pa7% muna 2015 kusvika 15% muna 2022, haisati yagara iri mumusika uye ine kodzero isina kusimba yemitengo yepolypropylene zvigadzirwa.Nekudaro, nekuenderera mberi kwekuvandudzwa kwesimba rakareruka uye makemikari zvigadzirwa muChina, maitiro akasiyana-siyana ekumusoro kwemafuta akasviba masosi epolypropylene ari kutendeuka, uye nekuuya kwe "propane" nguva, haizove kure pamberi penaphtha, propane uye marasha. ichakamurwa kuita zvikamu zvitatu zvenyika.
