Rutsigiro rweCatalyst

Chinotakura macatalyst chikamu chakakosha che catalyst yakasimba, dispersant, binder, negative carrier ye active component ye catalyst, uye dzimwe nguva ACTS se co-catalyst kana co-catalyst. Chinotakura macatalyst, chinozivikanwawo se support, chimwe chezvikamu zve supported catalyst. Kazhinji, chinhu chine maburi chine nzvimbo chaiyo, uye active component ye catalyst inowanzo batanidzwa pairi. Chinotakura chinoshandiswa zvakanyanya kutsigira active component, kuitira kuti catalyst ive nehunhu hwayo hwepanyama, nepo catalyst pachayo isina catalytic activity.

Zvinodiwa zvekutsigira Catalyst

1, inogona kuderedza huwandu hwezvinhu zvinoshanda, kunyanya simbi dzinokosha

2, inogona kugadzirwa muchimiro chakati

3. Kupisa pakati pezvinhu zvinoshanda kunogona kudzivirirwa kusvika pamwero wakati

4, inogona kuramba chepfu

5. Inogona kuva nemigumisiro yakafanana nechinhu chinoshanda uye chinhu chikuru chinobatsira.

Mhedzisiro yemutakuri we catalyst

1, kuderedza mutengo we catalyst

2, kuvandudza simba remuchina we catalyst

3. Kuvandudza kugadzikana kwekupisa kwe catalyst

4, wedzera basa rekubatsira uye kusarudza

5. Wedzera hupenyu hwe catalyst

Vatakuri vakawanda vekutanga vanounzwa

1. Alumina inoshanda: inotakura zvinhu zvinoshandiswa zvakanyanya mumaindasitiri. Mutengo wakaderera, inodzivirira kupisa zvakanyanya, inoenderana zvakanaka nezvinhu zvinoshanda.

2. Silica gel: makemikari ari muchimiro cheSiO2. Kazhinji inogadzirwa ne sodium silicate (na 2 si 3) acid. Silicate acid yakagadzirwa mushure mekushanda kwe sodium silicate ne acid. Silicic acid polymerization, condensation, uye chimiro che polymer hachina chokwadi.

SiO2 inotakura zvinhu zvinoshandiswa zvakanyanya, asi kushandiswa kwayo mumaindasitiri kushoma pane Al2O3, izvo zvinokonzerwa nekuoma kwekugadzirwa kwayo, kusasimba kwesimba rezvinhu zvinoshanda, kunyorova nyore neutsi hwemvura nezvimwe zvikanganiso.

3. Diatomite: SiO2 yechisikigo. Ine ma oxide esimbi mashoma uye organics, uye chimiro chayo chepore uye shanduko chaiyo pamusoro zvichibva pamavambo. Kurapa neacid kunofanirwa kushandiswa usati washandisa. Chimwe ndechekuvandudza huwandu hweSiO2 uye kuwedzera pamusoro chaipo, huwandu hwepore chaiyo uye radius yepore huru. Chechipiri ndechekuvandudza kugadzikana kwekupisa, mushure mekurapa neacid, inogona kuwedzera zvakanyanya pamusoro chaipo. Diatomite inonyanya kushandiswa kugadzira ma catalysts akasimba.

4, kabhoni inoshanda: chinhu chikuru iC, ine H, O, N, S uye dota shoma, nezvimwewo. Kabhoni inoshanda ine chimiro chisina kurongeka chematombo, kune boka rekabhoni, boka requinone, boka rehydroxyl uye boka rekabhoni inoshanda pamusoro. Kabhoni inoshanda inoratidzwa nemaburi akakura uye nzvimbo yakakura, kugadzikana kwekupisa uye yakakwirira.

5. TiO2: ine maumbirwo matatu ekristaro: anatase, plate titanium uye rutile. Sheet titanium ore inonetsa kugadzira nekuda kwekusagadzikana; Anatase inoumbwa patembiricha yakaderera ine huwandu hwe3.84 uye nzvimbo yakakura chaiyo. Inopisa pa600~1000°C, anatase inova rutile, iyo ine huwandu hwe4.22 uye nzvimbo diki chaiyo chaiyo.

6. Silicon carbide: nzvimbo yekunyunguduka kwesimbi dzecarbide yakakwira kupfuura 2000°C, ine kupisa kwakanyanya, kuomarara kwakanyanya, kuramba kupisa kwakasimba uye kuramba kukanganiswa, asi inongogadziriswa mumhepo ine oxygen. Saka SiC inowanzoshandiswa senzira yekutakura zvinhu zvinokonzeresa kupisa kwakanyanya.

7. Molecular sese: icrystalline silicate kana silicoaluminate, pore and cavity system inoumbwa ne silico-oxygen tetrahedron kana alumino-aluminium tetrahedron yakabatana ne oxygen bridge bonds. Ine high thermal stability, water thermal stability uye acid ne alkali resistance.
