Chii chinokonzerwa nerutsigiro rwecatalyst uye ndeapi anowanzo tsigiro?

Catalyst tsigiro chikamu chakakosha cheyakasimba catalyst. Ndiyo inoparadzira, binder uye tsigiro yezvikamu zvinoshanda zvechinokonzera, uye dzimwe nguva inotamba basa reCo catalyst kana cocatalyst. Rutsigiro rweCatalyst, inozivikanwawo serutsigiro, chimwe chezvikamu zvinotsigirwa zvinotsigira. Kazhinji chinhu chine porous chine imwe nzvimbo chaiyo. Izvo zvinoshandiswa zvinoshandiswa zvechinokonzera zvinowanzobatanidzwa pairi. Mutakuri anonyanya kushandiswa kutsigira zvikamu zvinoshanda uye kuita kuti catalyst ive nemhando chaiyo yemuviri. Nekudaro, iyo inotakura pachayo kazhinji haina catalytic chiitiko.

Zvinodiwa kuti catalyst rutsigiro
1. Inogona kuderedza kuwanda kwezvinhu zvinoshanda, kunyanya masimbi anokosha
2. Uye inogona kugadzirirwa mune imwe chimiro
3. Sintering pakati pezvinhu zvinoshanda zvinogona kudziviswa kusvika pamwero wakati
4. Inogona kuramba chepfu
5. Inogona kupindirana nezvikamu zvinoshanda uye kushanda pamwe chete nechinokonzera chikuru.

Mhedzisiro yerutsigiro rwecatalyst
1. Deredza mutengo we catalyst
2. Kuvandudza simba remagetsi re catalyst
3. Kuvandudza kugadzikana kwekupisa kwezvinokonzera
4. Chiito uye kusarudzwa kwekuwedzera catalyst
5. Wedzera hupenyu hunokonzeresa

Nhanganyaya kune akati wandei ekutanga vatakuri
1. Activated alumina: inonyanya kushandiswa mutakuri kune maindasitiri catalysts. Iyo yakachipa, ine yakanyanya kupisa inodzivirira, uye ine yakanaka hukama hwezvinhu zvinoshanda.
2. Silica gel: chimiro chemakemikari ndeyeSiO2. Iyo inowanzogadzirirwa ne acidifying girazi remvura (Na2SiO3). Silicate inoumbwa mushure mekunge sodium silicate inopindirana neasidhi; Silicic acid inopolymesa uye inonamira kuita mapolymer ane chimiro chisina chokwadi.
SiO2 inotakura inoshandiswa zvakanyanya, asi kushandiswa kwayo kwemaindasitiri ishoma pane iyo yeAl2O3, iyo inokonzerwa nekukanganisa kwakadai sekugadzirira kwakaoma, hukama husina simba nezvikamu zvinoshanda, uye nyore kunyura pasi pekugarisana kwemhute yemvura.
3. Molecular sieve: inonzi crystalline silicate kana aluminosilicate, iyo inonzi pore uye cavity system inoumbwa nesilicon oxygen tetrahedron kana aluminium oxygen tetrahedron yakabatanidzwa neoksijeni bhiriji bond. Iine kugadzikana kwakanyanya kwekushisa, kugadzikana kwehydrothermal uye asidi uye alkali kuramba
