Gulu la zoyeserera zapadziko lapansi

Pakadali pano, pali mitundu yambiri yadziko lapansiMa carealsstations oyeretsera omwe adakonzedwa ndikuyikidwa, ndipo njira zawo zogawika ndi zosiyanasiyana. Gulu losavuta komanso lokhalo limakhazikitsidwa chifukwa cha chothandizira, chomwe chitha kugawidwa m'mitundu iwiri: granolar ndi chisa ndi uchi. Malonda a granalar nthawi zambiri amagwiritsidwa ntchito γ- al2o3 ndionyamula ndi katundu wamkulu, yemwe amatha kukweza 10% mpaka 20%dziko lapansindi malo ena achitsulo ma okoma. Ili ndi kukana kwabwino, koma kukana kwake kumakhala kwakukulu, komwe kumakhudza mphamvu zake ndi chuma chake. Chitseko cha uchi chofuula nthawi zambiri chimagwiritsa ntchito dongqungsha, spllite, spludule, ndi chitsulo, komanso kuchuluka kwa zonyamulira, ndi mphamvu zochepa komanso zoyenera kuyika zitsulo zamtengo wapatali. Chonyamulira cha uchi chimakhala ndi kutentha pang'ono, kugwira bwino ntchito yotentha, mphamvu yamphamvu, komanso kugwiritsa ntchito bwino chuma, ndipo pakadali pano pali kugwiritsidwa ntchito ngati chonyamulira. Ngakhale njira yolumikizirana yotengera mawonekedwe a ma catalystsss ndi osavuta, kapangidwe ka atobala, makamaka zigawo zogwiritsidwa ntchito, sizinganenedwe momveka bwino.

Ngati magulu a catalystations ndi osiyana,dziko lapansiCatalytions imatha kugawidwa m'mitundu iwiri:dziko lapansiBasitsani ma metaly oxide oxade ndi dziko lapansi lokhazikika la oxade oxide oxade a careatchststs ndi ndalama zokhala ndi zopereka zachitsulo zamtengo wapatali. Wakaleyo ndi mtundu wa chotupa chomwe chimagwiritsidwa ntchito pano, chomwe chimakhala ndi chiyenga chabwino chotsimikizira kwa co ndi HC, koma chiyeretso chochepa pang'ono pa Nox. Wotsirizayo ali ndi chiyenga chabwino cha Nux, ndiye kuti chitsogozo chachikulu cha chitsutso cha mchira woyeretsa ma carelysts ku China.
