ZSM-5 Series Shape-selective Zeolites
ZSM-5 zeolite itha kugwiritsidwa ntchito pamakampani a petrochemical, mafakitale abwino amankhwala ndi magawo ena chifukwa cha mawonekedwe ake apadera amitundu itatu yowongoka pore ngalande, mawonekedwe apadera osankha crackability, isomerization ndi kununkhira kwake. Pakalipano, angagwiritsidwe ntchito ku chothandizira cha FCC kapena zowonjezera zomwe zingathe kusintha nambala ya octane ya mafuta, hydro/aonhydro dewaxing catalysts ndi unit process xylene isomerization, toluene disproportionation ndi alkylation. Nambala ya octane ya petulo imatha kukulitsidwa ndipo zomwe zili ndi olefin zitha kuonjezedwanso ngati zeolite ziwonjezedwa ku chothandizira cha FCC mumayendedwe a FBR-FCC. Pakampani yathu, ZSM-5 serial shape-selective zeolites ali ndi chiŵerengero chosiyana cha silica-aluminium, kuchokera ku 25 mpaka 500. Kugawidwa kwa tinthu kumatha kusinthidwa malinga ndi zofuna za makasitomala. Kutha kwa isomerization ndi kukhazikika kwa ntchito kumatha kusinthidwa acidity ikasinthidwa ndikusintha chiŵerengero cha silika-aluminium malinga ndi zomwe mukufuna.

| Njira Yophatikizira: Pansi pa kutentha kwambiri komanso kupanikizika kwambiri, ma zeolite a ZSM-5 adzapangidwa pambuyo pa hydrothermal pawiri crystallization, kusefa, kutsuka, kusintha ndi kuyanika pogwiritsa ntchito mchere wa aluminiyamu ndi silicate monga zinthu zazikulu. | ||
