【摘要】:介紹了RSS-2催化劑在中國石油蘭州石化公司航煤加氫裝置上的應(yīng)用情況,結(jié)果表明,以常減壓裝置常一線直餾煤油為原料,在進料量71.4t/h、反應(yīng)器入口溫度278.5℃、入口壓力3.72MPa、空速3.72h~(-1)、氫油比181的工藝操作條件下,經(jīng)加氫反應(yīng)、分餾、脫除硫化氫后,精制航煤中硫質(zhì)量分數(shù)由138μg/g降至3μg/g,脫硫率達到97.83%,堿性氮質(zhì)量分數(shù)由2.71μg/g降至0.12μg/g,脫堿氮率達到95.57%,產(chǎn)品質(zhì)量滿足3號噴氣燃料的質(zhì)量標準;為滿足低凝柴油的生產(chǎn)要求,在常一線直餾煤油中摻煉常二線,在常二線占混合原料質(zhì)量分數(shù)從25%增加到50%時,混合原料中硫質(zhì)量分數(shù)可降至20μg/g以下,滿足國Ⅳ低凝柴油的調(diào)和要求,說明該催化劑具有良好的加氫脫硫、脫堿氮效果。
