Özet
The use of heterogeneous catalysts obtained from waste in biodiesel production is of great importance in terms of waste management and waste recovery. In this study, heterogeneous catalyst was successfully obtained from waste cucumber stems (WCS) and its potential for biodiesel production via transesterification was investigated. The heterogeneous catalyst contains Ca, K, Mg, Si elements that play a role in biodiesel production. Biodiesel production potential was designed by selecting different temperature, time, methanol/oil molar ratio, and catalyst amount using response surface methodology (RSM). Waste cooking oil (WCO) was used for biodiesel production. The optimum values of these parameters were found to be 70 degrees C, 120 min, 15 wt% and 20:1, respectively. 93.7 % FAME yield was obtained using the obtained CaO catalyst. The heterogeneous catalyst obtained from WCS showed multiple reuse capacity up to 5 cycles. All these results showed that the heterogeneous catalyst obtained from WCS has strong biodiesel production activity and this approach has great potential in biodiesel production with its economic, sustainability and environmental benefits.
