Mawonekedwe a particle catalysts
Ma catalysts ang'onoang'ono amakhala ndi malo apamwamba komanso porosity, zomwe zimapangitsa kuti magwiridwe antchito azikhala bwino. Methanol yathu-mpaka{2}}zothandizira kununkhira ndi hydrogenation catalysts zonse zidapangidwa mwanjira inayake, kuwonetsetsa kukhazikika komanso kusankha bwino. Mwa iwo, zinthu za zeolite molecular sieve zilinso ndi ma topology apadera monga FAU/MWW.
Ma catalysts ndi gulu lofunikira la zida zomwe zimagwiritsidwa ntchito kwambiri m'minda yamankhwala, zachilengedwe, ndi mphamvu. Mapangidwe awo apadera a tinthu tating'onoting'ono komanso magwiridwe antchito amawapangitsa kukhala gawo lofunikira pamachitidwe ambiri amakampani. Kugwiritsiridwa ntchito kwa ma catalysts a particulate makamaka kumachokera kumadera awo apamwamba kwambiri, dispersibility yabwino, ndi ntchito zothandizira, zomwe zingathe kuchepetsa mphamvu yotsegula ndikuwongolera zomwe zimachitikira komanso kusankha zochita.
The catalytic activity of particulate catalysts mainly originates from their surface active sites. Masambawa amatha kutsitsa mamolekyu omwe amapangidwanso, kulimbikitsa kusweka ndi kupanga ma bond a mankhwala. The particulate kapangidwe osati kumawonjezera kukhudzana m'dera pakati chothandizira ndi reactants komanso facilitates otaya ndi kubalalitsidwa mu riyakitala, kuwongolera misa kutengerapo Mwachangu. Kuphatikiza apo, zopangira tinthu tating'onoting'ono nthawi zambiri zimakhala ndi mphamvu zamakina kwambiri, zolimbana ndi mavalidwe amthupi komanso dzimbiri lamankhwala panthawi yomwe akuchita, ndikuwonjezera moyo wawo wantchito.
