Abstract:：Cement kiln dust (CKD) is alkaline materials which contains solid material mixture mainly calcium oxide (CaO). The activation process of CKD was carried out with refluxing methanol at T 343.15 K for 90 minutes. The activation studies were performed based on methanol to oil weight ratio (1:1, 3:1, and 5:1). The transesterification performance studies were carried out in intensified reactor at T 343.15 K and 353.15 K with various methanol to oil mole ratios (200:1 and 300:1). It is found that CKD was activated at temperature of 340.15 – 355.15 K. Therefore, the use of CKD catalysts for transesterification at temperatures higher than355.15 Kwill not beeffective........
