Kodi zotsatira za chithandizo cha catalyst ndi ziti ndipo chithandizo chofala ndi chiyani?

Chithandizo cha Catalyst ndi gawo lapadera la chothandizira cholimba. Ndi chosungunula, chomangirira ndi chothandizira cha zigawo zogwira ntchito za chothandizira, ndipo nthawi zina chimagwira ntchito ngati chothandizira cha Co kapena cocatalyst. Chithandizo cha Catalyst, chomwe chimadziwikanso kuti chithandizo, ndi chimodzi mwa zigawo za chothandizira chothandizira. Nthawi zambiri ndi chinthu chokhala ndi mabowo chokhala ndi malo enaake. Zigawo zogwira ntchito za chothandizira nthawi zambiri zimamangiriridwa nacho. Chonyamuliracho chimagwiritsidwa ntchito makamaka kuthandizira zigawo zogwira ntchito ndikupangitsa chothandizira kukhala ndi mawonekedwe enieni. Komabe, chonyamuliracho chokha nthawi zambiri sichikhala ndi ntchito yothandiza.

Zofunikira pa chithandizo cha catalyst
1. Ikhoza kuchepetsa kuchuluka kwa zinthu zogwira ntchito, makamaka zitsulo zamtengo wapatali
2. Ndipo ikhoza kukonzedwa mu mawonekedwe enaake
3. Kusakaniza pakati pa zigawo zogwira ntchito kungapewedwe mpaka pamlingo winawake
4. Amatha kukana poizoni
5. Imatha kuyanjana ndi zinthu zogwira ntchito ndikugwira ntchito limodzi ndi chothandizira chachikulu.

Zotsatira za chithandizo cha catalyst
1. Chepetsani mtengo wa catalyst
2. Kulimbitsa mphamvu ya makina a chothandizira
3. Kukweza kukhazikika kwa kutentha kwa ma catalyst
4. Ntchito ndi kusankha kwa chothandizira chowonjezera
5. Kutalikitsa moyo wa catalyst

Chiyambi cha zonyamulira zingapo zoyambira
1. Alumina yogwiritsidwa ntchito: chonyamulira chomwe chimagwiritsidwa ntchito kwambiri pa zinthu zoyambitsa mafakitale. Ndi chotsika mtengo, sichimatentha kwambiri, ndipo chimakhala ndi mphamvu yabwino pa zinthu zogwira ntchito.
2. Silika gel: kapangidwe ka mankhwala ndi SiO2. Nthawi zambiri imakonzedwa ndi galasi lamadzi lopangitsa asidi (Na2SiO3). Silikate imapangidwa pambuyo poti sodium silicate yachitapo kanthu ndi asidi; Silikate imapanga polymer ndi kukhuthala kuti ipange ma polima omwe ali ndi kapangidwe kosadziwika.
SiO2 ndi chonyamulira chomwe chimagwiritsidwa ntchito kwambiri, koma ntchito yake m'mafakitale ndi yochepa kuposa ya Al2O3, yomwe imachitika chifukwa cha zolakwika monga kukonzekera kovuta, kusagwirizana kofooka ndi zinthu zogwira ntchito, komanso kusweka mosavuta chifukwa cha nthunzi ya madzi.
3. Sefa ya molekyulu: ndi silicate kapena aluminosilicate yopangidwa ndi silicon oxygen tetrahedron kapena aluminiyamu oxygen tetrahedron yolumikizidwa ndi chomangira cha okosijeni. Ili ndi kukhazikika kwakukulu kwa kutentha, kukhazikika kwa hydrothermal komanso kukana kwa asidi ndi alkali.
