Abstract
Transesterification of palm oil with methanol was studied using the CaO derived from the shell waste (CaOshell) and a commercial grade CaO (CaO-com). The effects of temperature, atmospheric gas and gas concentration in the treatment process on the catalytic activity of the obtained CaO were examined. Although the activity of the CaO-shell was much lower than the CaO-com when the treated gas was air, the activity of the CaO-shell was significantly improved with suitable treating condition. The activity of the CaO-shell was improved to the same level with the one of the CaO-com when the CaO-shell was treated with N 2. The activity of the CaO-shell was further improved when 50% of water was added into the treating gases. This is an abstract of a paper presented at the 19th International Congress of Chemical and Process Engineering and 7th European Congress of Chemical Engineering (Prague, Czech Republic 8/28/2010-9/1/2010).
