【摘要】 初步探索了ＳＯ_４^２－／ＺｒＯ２固体超强酸的失活机理．并着重研究了催化剂的两种再生方法：灼烧法和溶剂洗涤法。催化剂主要是因结焦而失活，高温灼烧能基本恢复催化剂原有活性．且再生效果与灼烧温度有关。溶剂洗涤法有一定的再生能力，但不显著．更多还原

【Abstract】 Labaratory experiments show that SO/ZrO2 solid catalyst is deactivated by coking and can be wen regenerated by caldnation in air at high temperature.or refreshed to certain extent by soluting it with ketone.更多还原
