“…In addition, reaction temperature is an important parameter for biodiesel production and decrease of costs. As temperature exceeds 333 K, some of the solvent (methanol) is evaporated without availability for the catalyst and oil that leads to the decrease in biodiesel production at higher temperatures [22]. In the present study, optimum temperature for biodiesel production for both catalysts was determined to be 333 K and maximum efficiency for KOH and NaOH at this temperature was 98 and 96 %, respectively.…”

Abstract.1 In this research biodiesel is produced from goat tallow in the presence of homogenous catalysts such as KOH and NaOH using trans-esterification process. For this purpose, effect of several parameters such as temperature, reaction time, methanol to oil ratio, type and concentration of a catalyst has been investigated. The results showed that the maximum biodiesel yield (96 and 98 %) was obtained using NaOH and KOH, respectively, and optimal conditions were determined. Also, to improve some properties of biodiesel, biodiesel was mixed with diesel at different ratio (B5-B100) and their properties such as flash point, cloud point, pour point, viscosity and density were measured. It was found that the properties of produced biodiesel is in the range of standard and can be used as a biofuel.

“…According to some reports the transesterification with high acid value and high water contents were carried out by using heteropolyacid H 3 PW 12 O 40. 6H 2 O (PW 12 ) as catalyst [8,12,21]. On the other hand, they are highly soluble in polar media like water and methanol.…”

“…Biodiesel is one of these renewable energy sources that attracted the attention of many researchers in the field. Biodiesel which is a blend of a mono alkyl ester of long-chain fatty acids is generally prepared by transesterification of various renewable sources, such as vegetable oil and waste cooking oil that have triglyceride in their composition [4][5][6][7]. According to the reported studies, replacing fossil diesel with biodiesel can reduce the emission of CO, particulate matters and unburned hydrocarbons up to 46.7, 66.7 and 45.2%, respectively; however, NOx emission increases [8].…”

Gamma alumina is one of the widely used supports in catalyst preparation, possessing a high specific surface area and good thermal stability. Spray drying is an efficient way to produce narrow particle size distribution and spherical shape powders. In this study, spray drying method has been implemented to prepare microspherical nanoporous gamma alumina with a high specific surface area. The nanoporous gamma alumina support was utilized in the preparation of various heterogeneous base catalysts. The highest biodiesel yield of 99% was obtained at 6 wt% loading of K/c-Al 2 O 3 catalyst, using waste cooking oil as feedstock. The obtained results revealed the great potential of the synthesized nanoporous gamma alumina as an effective support for heterogeneous base catalysts preparation in the transesterification reaction.
