Widely used catalysts in biodiesel production: a review

“…Impregnation followed by calcination (600 C) was used to synthesize the Fe-Mn-MoO 3 /ZrO 2 catalyst, which could provide a high 95.6 AE 0.15% yield of FAME. 333 It is interesting to observe that ZrO 2 and MoO 3 /ZrO 2 gave a lower FAME yield of 48.6 AE 1.14 and 73.0 AE 0.25%, respectively. The high activity of the Fe-Mn-MoO 3 /ZrO 2 catalyst is attributed to the high surface area (49.5 m 2 g À1 ) and availability of huge active sites (2411 mmol g À1 ) in the catalyst.…”

Synthesis of nanomagnetic sulphonated impregnated Ni/Mn/Na2SiO3 as catalyst for esterification of palm fatty acid distillate

“…[38][39][40] According to the TGA analysis of the NiO-MnO/AC catalyst, the weight loss appeared between 452.8 C and 655.3 C, which can be attributed to the decomposition of MnO and NiO. 41,42 The TGA analysis of the Na 2 SiO 3 -NiO-MnO/AC catalyst showed a decomposition at 289.4 C and 569.2 C.…”
