Hunhu hwezvinhu zvinokonzeresa
Particulate catalysts ine yakakwira chaiyo nzvimbo uye porosity, inovandudza maitiro ekuita. Yedu methanol-ku{2}}aromatics catalysts uye hydrogenation catalysts zvese zvakagadzirwa muchidimbu, zvichitaridza kugadzikana kwakanaka uye kusarudza. Pakati pazvo, zeolite molecular sieve zvigadzirwa zvakare zvine yakasarudzika topology senge FAU/MWW.
Particulate catalysts ikirasi yakakosha yezvinhu zvinoshandiswa zvakanyanya mumakemikari, zvakatipoteredza, uye masimba masimba. Yavo yakasarudzika particle morphology uye catalytic performance inoita kuti ive chinhu chakakosha mumaindasitiri mazhinji maitiro. Iko kushandiswa kwema particulate catalysts kunonyanya kuenderana nepamusoro penzvimbo yavo, yakanaka dispersibility, uye catalytic chiitiko, chinogona kuderedza zvakanyanya activation simba uye kuvandudza chiyero chekuita uye kusarudzwa mukuita kwemakemikari.
Iyo catalytic chiitiko che particulate catalysts inonyanya kutangira kubva kune yavo nzvimbo inoshanda. Aya masaiti anogona adsorb reactant mamorekuru, achisimudzira kutyora uye kuumbwa kwemakemikari bond. Iyo yakasarudzika dhizaini haingowedzere nzvimbo yekubatana pakati peiyo catalyst uye reactants asi zvakare inofambisa kuyerera uye kupararira muiyo reactor, inovandudza kuwanda kwekufambisa kushanda. Uyezve, ma catalysts anowanzo kuve neakanyanya simba remuchina, kuramba kupfeka kwemuviri uye kuora kwemakemikari panguva yekuita maitiro, kuwedzera hupenyu hwavo hwesevhisi.
