Optimization of Process Variables for Biodiesel Production Using the Nanomagnetic Catalyst CaO/NaY‐Fe₃O₄

Abstract

A nano-magnetic catalyst CaO/NaY-Fe 3 O 4 was synthesized and used as a catalyst for biodiesel production from canola oil. The structure of the synthesized catalysts was characterized using several methods such as XRD, FESEM, BET, FT-IR and VSM. In order to optimize the influence of the operating variables, such as methanol to canola oil molar ratio, the amount of catalyst and reaction time on the yield of transesterification reaction, an experimental design was applied based on the Box-Behnken method. The optimum values of these variables were predicted by the Cubic model. Maximum amount of methyl esters (95.37%) was achieved under the optimum operating conditions and it was in excellent agreement with the experimental result within an error less than 5%.

Nanoferrites heterogeneous catalysts for biodiesel production from soybean and canola oil: a review

“…The methanol to oil molar ratio can be ranged between 6 and 10, and catalyst loading can be varied between 4 and 5.5%. The biodiesel production yield of 85–95% can be obtained between these ranges using CaO/NaY-Fe 3 O 4 magnetic nanocatalyst (Firouzjaee and Taghizadeh 2017 ). Transesterification of canola oil can be carried out using Li/Fe 3 O 4 and Li/ZnO–Fe 3 O 4 with a molar ratio of 3:1 and a small catalyst wt.% loading of 0.8.…”

Esterification of Palm Fatty Acid Distillate Using a Sulfonated Mesoporous CuO‐ZnO Mixed Metal Oxide Catalyst

“…b presents the BJH pore diameter distribution pattern of the mesoporous catalysts in the range of 2.88–3.35 nm. By applying a higher concentration of Cu, the pore diameter was shifted to lower values which were ascribed to the deposition of the metal oxide nanoparticles on the inner walls of the mesopores . However, with higher metal oxide concentration, the pore size distribution was still in the mesopore range, which confirmed that the mesopore structure had not collapsed after loading the metal oxide nanoparticles onto the host structure .…”

Fabrication and Optimization of Nanocatalyst for Biodiesel Production: An Overview

“…To overcome these shortcomings, Firouzjaee and Taghizadeh, 2017 reported the nanomagnetic based zeolite catalyst CaO/NaY-Fe 3 O 4 which shows excellent stability at high temperatures, along with ease in the separation process. Various parameters are being monitored, revealing a conversion efficiency of 95.37% using canola oil as feedstock material (Firouzjaee and Taghizadeh, 2017).…”
