The treatments are : caustic treating for light gasoline , selective hydrotreating for medium gasoline and conventional hydrotreating for heavy gasoline 最輕餾份經(jīng)苛性堿處理,中間餾份經(jīng)選擇性加氫處理,而最重餾份則經(jīng)一般加氫處理來脫硫。
These years we have developed strongly acidic macroreticular catalysts based on styrene dvb . catalyst resin d006 for mtbe tame etbe , also as catalyst use for producing tba by isobutene hydration and direct producing gasoline with high octane rating by light gasoline etherification . d008 for sba ipa , also can be used for making methyl ethyl ketone by acetone one - stepping process , tert - butanol by isobutene hydration , etherified gasoline by the etherification of isopentene and isohexene in light gasoline with methyl alcohol , high 以上,增強了催化活性,從而延長了使用壽命,提高了周期產(chǎn)量二低溫活性好,選擇性強,提高了mtbe的純度,降低了雜質(zhì)含量三在同樣裝置中,可增大負荷,提高產(chǎn)量,降低生產(chǎn)成本和費用。
