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，提高了周期產量二低溫活性好，選擇性強，提高了mtbe的純度，降低了雜質含量三在同樣裝置中，可增大負荷，提高產量，降低生產成本和費用。
