Inkxaso ye-Catalyst yinxalenye ekhethekileyo ye-catalyst eqinile. I-dispersant, i-binder kunye nenkxaso yamacandelo asebenzayo e-catalyst, kwaye ngamanye amaxesha idlala indima ye-Co catalyst okanye i-cocatalyst. Inkxaso ye-Catalyst, eyaziwa ngokuba yinkxaso, yenye yamacandelo e-catalyst exhaswayo. Ngokuqhelekileyo yimathiriyeli ene-porous kunye nommandla othile ocacileyo. Amacandelo asebenzayo e-catalyst ahlala eqhotyoshelwe kuyo. Umthwali usetyenziselwa ikakhulu ukuxhasa amacandelo asebenzayo kwaye wenze i-catalyst ibe neempawu ezithile zomzimba. Nangona kunjalo, umthwali ngokwawo ngokubanzi akanalo umsebenzi wokuvuselela.
Iimfuno zenkxaso ye-catalyst
1. Inokunciphisa ubuninzi bezinto ezisebenzayo, ngakumbi iintsimbi ezixabisekileyo
2. Kwaye inokulungiswa ibe yimo ethile
3. I-Sintering phakathi kwamacandelo asebenzayo inokuthintelwa kwinqanaba elithile
4. Uyakwazi ukumelana netyhefu
5. Iyakwazi ukusebenzisana namacandelo asebenzayo kwaye isebenze kunye ne-catalyst ephambili.
Impembelelo yenkxaso ye-catalyst
1. Ukunciphisa iindleko ze-catalyst
2. Ukuphucula amandla omatshini we-catalyst
3. Ukuphucula ukuzinza kwe-thermal ye-catalysts
4. Umsebenzi kunye nokukhetha kwe-catalyst eyongezelelweyo
5. Bandisa ubomi obukhuthazayo
Intshayelelo kubathwali abaninzi abaphambili
1. I-alumina esebenzayo: eyona nto isetyenziswa kakhulu kwi-catalysts yezoshishino. Ixabiso eliphantsi, inokumelana nobushushu obuphezulu, kwaye inobudlelwane obuhle kumalungu asebenzayo.
2. Ijeli ye-silica: i-chemical composition yi-SiO2. Ngokuqhelekileyo ilungiswe ngeglasi yamanzi e-acidifying (Na2SiO3). I-silicate yenziwe emva kokuba i-sodium silicate isabela nge-asidi; I-asidi ye-Silicic i-polymerize kwaye idibanise ukwenza iipholima ezinokwakheka okungaqinisekanga.
I-SiO2 yinkampani esetyenziswa ngokubanzi, kodwa ukusetyenziswa kwayo kwimizi-mveliso kungaphantsi kwe-Al2O3, ngenxa yeziphene ezifana nokulungiswa okunzima, ukudibanisa okubuthathaka kunye namacandelo asebenzayo, kunye nokulula ngokulula phantsi kokubambisana komphunga wamanzi.
3. I-molecular sieve: i-crystalline silicate okanye i-aluminosilicate, eyi-pore kunye ne-cavity system eyenziwe nge-silicon oksijini ye-tetrahedron okanye i-aluminium i-tetrahedron ye-oxygen edityaniswe yibhondi ye-oxygen bridge. Unozinzo oluphezulu lwe-thermal, ukuzinza kwe-hydrothermal kunye ne-asidi kunye nokumelana ne-alkali
