MaZeolite iboka rezvicherwa zvinongoitika zvave zvichishandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwezvakasiyana zvivakwa. Pakati pemhando dzakasiyana-siyana dzezeolite, ZSM-23 inomira seyakanyanya inoshanda ma molecular sieve ine huwandu hwakawanda hwekushandisa mu petrochemical uye makemikari maindasitiri. Muchinyorwa chino, tichaongorora maitiro, synthesis, uye mashandisirwo eZSM-23, ichijekesa kukosha kwayo mumunda wecatalysis uye adsorption.
Zeolite ndeye crystalline aluminosilicate minerals ine porous chimiro uye yakakwirira pamusoro penzvimbo. Izvi zvivakwa zvinovaita vakanyanya kukwikwidza kune zvikumbiro senge adsorption, ion exchange, uye catalysis. ZSM-23, kunyanya, imhando yezeolite inozivikanwa neyakasiyana pore chimiro uye yakakwirira kusarudza kune mamwe mamorekuru. Yayo molecular sieve zvimiro inoita kuti ive yakakosha zvinhu zvekuparadzanisa uye kuchenesa akasiyana makomisheni mumaindasitiri maitiro.
Iyo synthesis yeZSM-23 inosanganisira kushandiswa kweakananga precursors uye maitiro ekuita kudzora kuumbwa kweiyo crystalline chimiro. Kazhinji, ZSM-23 inogadzirwa uchishandisa hydrothermal process, uko musanganiswa wealumina, silica, uye chimiro-inotungamira mumiriri inoiswa pasi pekupisa kwakanyanya uye kumanikidzwa. Iyo inokonzeresa crystalline zvinhu zvinobva zvanyatsobatwa kubvisa chero tsvina uye optimize zvimiro zvayo kune chaiwo maapplication.
Imwe yeakakosha maitiro eZSM-23 ndeye microporous dhizaini, iyo ine yakabatana chiteshi uye makeji ezviyero chaizvo. Ichi chakasarudzika chimiro chinobvumira ZSM-23 kuti isarudze adsorb mamorekuru zvichienderana nehukuru uye chimiro, ichiiita chinhu chakanakira nzira dzekuparadzanisa. Pamusoro pezvo, iyo acidic chimiro cheZSM-23's pamusoro inoita kuti ikwanise kukonzeresa maitiro akasiyana emakemikari, ichiwedzera kuwedzera kwayo kushandiswa mumaindasitiri maitiro.
Muindasitiri yepetrochemical, ZSM-23 inoshandiswa zvakanyanya sechinhu chinokonzeresa kushandurwa kwemahydrocarbon kuita zvigadzirwa zvakakosha se peturu uye petrochemical intermediates. Kusarudzika kwayo kwepamusoro kune mamwe ma hydrocarbon mamorekuru kunoita kuti ive chinhu chakakosha mumatanho senge catalytic cracking uye hydrocracking, uko kushandurwa kwakanaka kwemafeedstocks kuita zvigadzirwa zvinodiwa kwakakosha pakubudirira kwese kwekushanda.
Uyezve, ZSM-23 inoita basa rakakosha mukugadzirwa kwemakemikari akanaka uye epakati pemishonga. Kugona kwayo kusarudza adsorb uye kukonzeresa chaiwo mamorekuru kunoita kuti ive chishandiso chakakosha chekubatanidza yakaoma organic komisheni ine kuchena kwakanyanya uye goho. Pamusoro pezvo, ZSM-23 inoshandiswa mukucheneswa kwemagasi uye zvinwiwa, uko mamolecular sieving properties inogonesa kubviswa kwetsvina netsvina kubva kuhova dzakasiyana.
Iko kushandiswa kwakasiyana-siyana kweZSM-23 kunowedzera kune kwezvakatipoteredza zvikumbiro zvakare. Kushandiswa kwaro sechinhu chinokonzeresa kurapwa kwemagasi emhepo uye kubviswa kwezvinosvibisa kubva mumarara eindasitiri kunoburitsa kukosha kwayo mukugadzirisa matambudziko ezvakatipoteredza. Nekufambisa kushandurwa kwehutsi hunokuvadza kuita makemikari asingakuvadzi, ZSM-23 inobatsira kuderedza kusvibiswa kwemhepo uye kuchengetedza kwezvakatipoteredza.
Munzvimbo yesimba rinodzokororwa, ZSM-23 yakaratidza chivimbiso mukugadzirwa kwemafuta ehupenyu kuburikidza neshanduko inokonzeresa yezvikafu zvakatorwa nebiomass. Kugona kwayo kushandura zvakasarudzwa zvikamu zvebiomass kuita mafuta akakosha uye makemikari anowirirana nekufarira kuri kukura mune inoenderera uye ine hushamwari hwemagetsi masosi.
Izvo zvakasiyana-siyana zveZSM-23 zvakakwezvawo kutarisa mumunda we nanotechnology, uko kushandiswa kwayo se template yekubatanidza kwezvinhu nanostructured yakaongororwa. Nekushandisa iyo chaiyo pore chimiro cheZSM-23, vaongorori vakakwanisa kugadzira novel nanomaterials ine yakarongedzwa zvivakwa zvekushandisa mumagetsi, catalysis, uye kuchengetedza simba.
Mukupedzisa, ZSM-23 inomira pachena seyakanyanya kushanda mamorekuru sieve ine akasiyana mashandisirwo mumaindasitiri epetrochemical, makemikari, uye zvakatipoteredza. Yayo yakasarudzika pore chimiro, yakasarudzika adsorption kugona, uye catalytic zvivakwa zvinoita kuti ive chinhu chakakosha kune akasiyana maindasitiri maitiro. Sezvo tsvakiridzo nebudiriro mundima yezeolite iri kuramba ichienderera mberi, mukana wekuwedzera hutsva uye mashandisirwo eZSM-23 ari kuvimbisa, achigadzira nzira yekuenderera kwayo kukosha mukugadzirisa zvinodikanwa zvemaindasitiri emazuva ano.
