چکیده انگلیسی


• Palm fatty acid distillate is successfully converted to methyl esters.
• SO42−SO42−/TiO2–SiO2 is utilized as a solid acid catalyst.
• Conversion of 93.3% is achieved in 3.12 h of reaction time.
• The responses have been optimized statistically using Central Composite Design.

The use of by-products, particularly in the biodiesel industry, has gained much attention owing to their potential in countering higher feedstock costs. A low-value by-product of palm oil refining, the palm fatty acid distillate (PFAD), was utilized as a feedstock for biodiesel preparation with the aid of a solid acid catalyst, SO42−SO42−/TiO2–SiO2. A central composite design is applied to optimize the major influential manipulate variables. The analysis of variance identifies the methanol/PFAD molar ratio as having a dominant effect on methyl ester conversion, followed by catalyst amount and reaction time respectively. The utilization of PFAD with the aid of a solid acid catalyst results in 93.3 ± 1.02% conversion at the most optimized reaction conditions of 2.97 ± 0.04 wt% for the catalyst amount, 5.85 ± 0.14 methanol/PFAD molar ratio and 3.12 ± 0.14 h of reaction time.
