Zeolite catalysts inoita basa rakakosha muindasitiri yepetrochemical, kufambisa maitiro akasiyana emakemikari akadai secatalytic kupaza, hydrocracking, uye isomerization. Pakati pemhando dzakawanda dzezeolite, ZSM uye ZSM23 inonyanya kukosha kune yavo yakasarudzika zvivakwa uye mashandisirwo. Muchikamu chino, tichaongorora kukosha kweZSM neZSM23 zeolites, maitiro avo, uye maitiro avo pane petrochemical sector.
ZSM neZSM23 inhengo dzemhuri yezeolite, iri crystalline, microporous zvinhu zvine matatu-dimensional framework chimiro. Aya mazeolite anoumbwa nesilicon, aruminiyamu, uye maatomu eokisijeni, achigadzira network yematanho nemakomba anobvumira kusarudzwa kwekushambadzira uye catalysis yemamorekuru. Iyo yakasarudzika pore dhizaini uye acidity yeZSM neZSM23 inovaita zvinonyanya kushanda zvinokonzeresa kune dzakasiyana siyana petrochemical reaction.
ZSM zeolite, kusanganisira ZSM23, dzinozivikanwa nehupamhi hweasidhi uye chimiro chekusarudza, izvo zvinovagonesa kukonzeresa kushandurwa kwemamorekuru ehydrocarbon kuita zvigadzirwa zvidiki, zvakakosha. Ichi chivakwa chinonyanya kubatsira mukutsemukira kwecatalytic, maitiro anoshandiswa kuputsa mahydrocarbons anorema kuita zvidimbu zvakareruka senge peturu nedhiziri. ZSM23, imwe mhando yeZSM zeolite, inoratidza yakakwidziridzwa inosimudzira chiitiko uye kusarudza, zvichiita kuti ive yakakosha inokonzeresa yekunatsa maitiro.
Imwe yeakakosha mashandisirwo eZSM neZSM23 zeolites iri mukugadzirwa kwepamusoro-octane peturu kuburikidza neisomerization yechiedza naphtha. Isomerization inosanganisira kurongazve chimiro chemomecular yemahydrocarbons kuti ivandudze chiyero cheoctane, uye ZSM neZSM23 zeolite dzinoshandiswa kufambisa maitiro aya nekuda kwekugona kwavo kushandura ma hydrocarbons akatwasuka kuita maesomers ane matavi epamusoro, ane nhamba dzepamusoro dzeoctane.
Zvakare, ZSM neZSM23 zeolite dzinoshandiswa muhydrocracking, maitiro anoshandura anorema mahydrocarbons kuita akareruka, akakosha zvigadzirwa senge peturu, dhiziri, uye jet mafuta. Kusarudzwa kwechimiro cheiyi zeolite kunobvumira kutsemuka kwakasarudzika kwema-chain-chain hydrocarbons, zvichikonzera kugadzirwa kwemafuta emhando yepamusoro ane zvivakwa zvakavandudzwa.
Pamusoro pebasa ravo mukunatsa, ZSM neZSM23 zeolites zvakare inoshandiswa mukugadzira petrochemical intermediates uye akakosha makemikari. Kugona kwavo kukonzeresa maitiro akasiyana-siyana, akadai sealkylation uye kunhuhwirira, kunoita kuti ive yakakosha mukugadzirwa kwemakomisheni akakosha anoshandiswa mukugadzira mapurasitiki, detergent uye zvimwe zvigadzirwa zvemaindasitiri.
Izvo zvakasarudzika zvivakwa zveZSM neZSM23 zeolites zvinoita kuti vatsvakwe zvakanyanya muindasitiri yepetrochemical. Nzvimbo yavo yakakwirira yepamusoro, chimiro chepore, uye acidity inobatsira pakuita kwavo kunoshamisa, zvichiita kuti kushandurwa kwakanaka kwemahydrocarboni kuita zvigadzirwa zvakakosha. Uyezve, kugadzikana kwavo kwekupisa uye kemikari kunoita kuti vagare vakasimba macatalysts akakodzera mamiriro anodiwa e petrochemical process.
Kuvandudzwa uye kukwidziridzwa kweZSM neZSM23 zeolite kwave kuri nyaya yekutsvagisa uye hunyanzvi mundima yecatalysis. Masayendisiti nemainjiniya anoenderera mberi nekuongorora nzira dzemanovel synthesis uye nzira dzekugadzirisa kusimudzira zvimiro zveiyi zeolite, nechinangwa chekuvandudza mashandiro avo uye kuwedzera mashandisiro avo muindasitiri yepetrochemical.
Mukupedzisa, ZSM neZSM23 zeolites inoita basa rakakosha muindasitiri yepetrochemical, inoshanda seyakasiyana-siyana uye inoshanda inokonzeresa maitiro akasiyana emakemikari. Zvinhu zvavo zvakasiyana-siyana, zvinosanganisira high acidity, kusarudzwa kwechimiro, uye kugadzikana kwekupisa, zvinoita kuti zvive zvakakosha mukugadzirisa kuputika, isomerization, hydrocracking, uye kugadzirwa kwepetrochemical intermediates. Sezvo kudiwa kwemafuta emhando yepamusoro uye makemikari kuri kuramba kuchikura, kukosha kweZSM neZSM23 zeolites mukufambisa kugona uye kusimba kwekushanda kwepetrochemical hakugone kuwedzeredzwa.
