“…Waste oils can be co-treated with animal fats from slaughterhouses and fleshing oils from leather industries to gather cheap biodiesel feedstock (Alptekin et al, 2014). FW can also be used to grow microorganisms, microalgae or insects rich in lipids from which biodiesel can be produced (Ghanavati et al, 2015;Kiran et al, 2014;.…”

“…In order to decrease the high content of FFA, two-stage pre-treatment processes have been reported by some researchers 11,32 . It should be noted that the increase in pre-treatment stages leads to the reduction in ester yield because of the ester solubility in methanol 33 . Therefore, onestage pre-treatment was applied for reduction of the FFA content during the esterification reaction.…”

In the present research, the esterification of waste chicken fat (WCF) by two different homogeneous and heterogeneous catalysts has been studied. Sulfonate and carboxylate functionalized multiwall carbon nanotubes (MWCNT-SO 3 H, MWCNT-COOH) were applied as useful heterogeneous acidic catalysts during esterification of WCF. According to the experimental results, sulfonate-modified MWCNT showed more effective catalytic activity than did carboxylate-modified MWCNT. It was found that free fatty acid (FFA) of WCF in the single stage esterification of WCF had decreased down to less than 1 % in the presence of 25 % MWCNT-SO 3 H catalyst (according to the amount of FFA), reactor temperature of 90 °C with contact time of 3 h, and methanol/FFA molar ratio of 30:1.

“…The bio-diesel applied for the extraction test was produced by using kitchen oil at the refinery (Alptekina et al, 2014). Liquid-liquid extraction is based on the principle that the components of a mixture can be redistributed into two liquid phases, based on the mass transfer of one component from one liquid phase to another (Fair and Humphrey, 1983).…”
