Biodiesel production by esterification of palm fatty acid distillate
Production of fatty acid methyl ester (FAME) from palm fatty acid distillate (PFAD) having high free fatty acids (FFA) was investigated in this work. Batch esterifications of PFAD were carried out to study the influence of: including reaction temperatures of 70–100 1C, molar ratios of methanol to PFAD of 0.4:1–12:1, quantity of catalysts of 0–5.502% (wt of sulfuric acid/wt of PFAD) and reaction...
متن کاملMicrowave-assisted biodiesel production by esterification of palm fatty acid distillate.
In the current research work, effect of microwave irradiation energy on the esterification of palm fatty acid distillate (PFAD) to produce PFAD methyl ester / biodiesel was intensively appraised. The PFAD is a by-product from refinery of crude palm oil consisting >85% of free fatty acid (FFA). The esterification reaction process with acid catalyst is needed to convert the FFA into fatty acid me...
متن کاملKinetics Study of Free Fatty Acids Esterification for Biodiesel Production from Palm Fatty Acid Distillate Catalysed by Sulfated Zirconia
Kinetic study of free fatty acids (FFAs) esterification for biodiesel production from palm fatty acid distillate (PFAD) using sulfated zirconia (S-ZrO2) prepared by solvent-free method calcined at low temperature as the heterogeneous catalyst was studied. The reaction was performed in a batch-stirred reactor at the different temperature to obtain the kinetic data. The effect of reaction conditi...
متن کاملCatalytic synthesis of biodiesel from high free fatty acid-containing feedstocks.
Recyclable and reusable heterogeneous diarylammonium catalysts are highly effective in catalyzing the esterification of the free fatty acid (FFA) present in greases to methyl esters to reduce the FFA content from 12-40 wt% to 0.5-1 wt%; the resulting ester-glyceride mixture (pretreated grease) could then be readily converted to methyl esters by base-catalyzed transesterification.
متن کاملKinetic Investigation of Enzymatic Synthesis of Sucrose Fatty Acid Esters from Sucrose and Non-edible Rice Bran Fatty Acid
Enzymatic synthesis of sugar fatty acid esters were performed in an organic solvent using Immobilized Rhizomucor miehei (RMIM) lipase with sucrose and non-edible rice bran fatty acid as substrates. The maximum conversion of sucrose esters up to 78% obtained when sucrose and non-edible rice bran fatty acid were reacted in molar ratio of 1:8, using n-butanol as a solvent and 1% molecular sieves w...
