摘　　要：Φ３８×３；５×２０００的不锈钢固定床积分反应器中对ＣｕＣｒＫ／γ－Ａｌ_２Ｏ_３（组成为ＣｕＯ２０ｗｔ％，Ｃｒ_２Ｏ_３５ｗｔ％，Ｋ_２ＣＯ_３１６ｗｔ％．其余为γ－Ａｌ_２Ｏ_３）进行了活性测试．测试条件为：催化剂尺寸φ２．５×２．５～３．５，负荷０．０８ｇ糠醛／ｇ·催化剂·ｈ．反应温度１３０～２１０℃，压力为常压．在这些条件下，催化反应共９８４ｈ，糠醛转化率高于９８．５％，糠醛选择性高于９８．５％．对失活后的催化剂进行了氧化再生．２００℃以下氧化再生主要是聚合物和氧作用，生成糠醛、糠醇，并脱除掉；２００～３００℃温度范围内的氧化再生是聚合物和氧作用生成ＣＯ_２和水．氧化再生过程中Ｃｕ￣０基本上未被氧化，大部分铜仍以Ｃｕ￣０的形式存在．In φ38 × 3. 5× 2000 mm stainless fixed bed integral reactor, we investigated the activity of CuCrK/γ-Al_2O_3. At the following conditions: catalyst size is φ2. S× 2. 5～3. 5,load amount is 0. 08 g furfural/g·cat·h ,reaction temperature is 130～210 ℃, pressure is 1atm, catalyst reacted 984 hours, while furfural conversion was greater than 98. 5% and furfurl alcohol selectivity was greater than 98. 5%. When the catalyst was regenarated,below 200℃ some polymers reacted with oxygen and mainly formed furfural and furfuryl alcohol , then they were removed; between 200 and 320℃ ,mainly formed CO_2 and H_2O.
