- USY分子篩 -


產(chǎn)品特點及應(yīng)用

USY分子篩是以NaY為原料，經(jīng)過一系列處理過程（如稀土處理、銨鹽處理、水熱超穩(wěn)性及化學(xué)脫鋁補硅等）制備的Y型分子篩，分子篩的晶胞大小、酸中心密度、酸強度等可以調(diào)變，分子篩的稀土含量也可以調(diào)變，以滿足不同催化劑的目的要求。

主要用于生產(chǎn)FCC催化裂化催化劑；用于生產(chǎn)優(yōu)質(zhì)乙烯原料及較重質(zhì)餾分油的重壓加氫裂化催化劑的酸性組分，尤其是USY型為重質(zhì)餾分油進行加氫裂化中，所使用催化劑的關(guān)鍵活性組分，通過該劑可生產(chǎn)優(yōu)質(zhì)柴油、航煤及石腦油。
