摘要
研究了固体超强酸(SO2-4/ZrO2)催化剂的酸性及异丁烷-1-丁烯烷基化反应性能,结果表明,固体超强酸的酸性与焙烧温度有关,适当提高焙烧温度有利于样品酸强度的提高,但焙烧温度过高会导致脱硫,使样品酸强度和酸量降低.固体超强酸的异丁烷/1-丁烯烷基化催化反应活性与其酸性相对应,酸性强,反应活性高,但催化剂的活性衰减很快,这是催化剂表面的快速积炭所致.
The acidity and reactivity of superacid(SO^(2-)_4/ZrO_2) catalysts in the iso-butane/1-butene alkylation were investigated. It was found that the acidity of the solid superacid is related to the baking temperature, and higher baking temperature is advantageous to increasing the acidic strength of the catalysts, but too high baking temperature resulted in the decrease of the acidic strength and amount. It was also found that the reactivity of superacid(SO^(2-)_4/ZrO_2) catalysts in the iso-butane/1-butene alkylation corresponds to the acidity, the stronger the acidity is, the higher the reactivity is. But the stronger acidity resulted in the fast decrease of activity, which was attributed to the fast carbon deposit on the catalyst surface.
