“…Yan et al [94] reported that the Zn 3 La 1 catalyst they prepared was recycled 17 times in a batch reactor without loss of activity and maintained a high FAME yield (92.3%) for 70 days in a continuous tubular flow reactor. In comparison CaO and MgO based catalysts showed a high number of reuse potentiality as above 16 uses with Ca/Ce oxide [74]. Mixed KF/CaO could be a very attractive heterogeneous catalyst with repeatability for 16 cycles to achieve biodiesel yield 97% -91% [82].…”

“…Thitsartarn et al [74] prepared a Ca/Ce oxide catalyst which can be reused up to 15 cycles with the retained catalytic performance. After each reaction cycle, the catalyst was separated from the liquid product by filtration, washed with n-hexane to clean up the catalyst's surface, dried at 120˚C and reused for the next reaction cycle without recalcination.…”

The activity of a catalyst in transestrification reaction usually declines with repeated uses and this limits the possibility to use it many times. This paper presents a review of various techniques used to evaluate the activity changes, the recycling processes for calcium and magnesium oxides based heterogeneous catalysts for biodiesel production. The activity of calcium and magnesium oxides based catalysts declines due to leaching, surface or active sites poisoning by reactant or product molecules and modification of physical aspects. Physico-chemical methods (AAS, BET, CO 2 -TPD, EDS, FTIR, ICP-AES, SEM, TG/DTA and XRD) were used to check the catalyst modification and to confirm the deactivation. When separated from the reaction mixture by filtration, the catalyst could be reused without any treatment or recycled by washing, drying or/and recalcination. Between various recycling processes for calcium and magnesium oxides based catalysts, mixed oxides showed less leaching and performed FAME or FAEE yield >90% with reusability.

“…Within the variety of solid basic catalysts that are currently produced, those supported on mesoporous silica are of interest since the dispersion of the active phase on a large specific surface (>800 m 2 ) usually generates a better active site availability and promotes mass transfer [23,24]. However, one of the drawbacks of using these materials is the leaching of the active species to the reaction mixture, which considerably reduces the useful life of the catalyst [25][26][27][28].…”

“…Further, Ca‐doped Ce‐integrated catalyst supported on SBA‐15 was prepared to catalyze an esterification reaction . The maximum Si/Ce molar ratio incorporated into the mesoporous framework was five and an impregnation of 30 wt % Ca showed good catalytic performance in the transesterification of palm oil with methanol.…”

Depletion of oil reserves, increasing prices of petroleum products, and environmental concerns related to air pollution are the main driving forces for utilizing renewable energy resources to replace fossil fuels. Vegetable oils can be used to produce biodiesel. Biodiesel is obtained by transesterification of vegetable oil with alcohol using homogeneous or heterogeneous catalysts. In the industry, biodiesel is produced by heterogeneous catalysts due to high activity and selectivity, better reusability, reduction in processing steps, and wastes. The catalytic activity of catalysts depends on the strength and type of intrinsic basic or/and acid properties. Biodiesel production using heterogenous catalysts depends on the various reaction parameters such as reaction time, temperature, molar ratio of alcohol to oil, catalyst amount, and stirring speed. In this paper, the catalytic transesterification of various feedstocks such as edible oil, non‐edible oil, and waste using heterogeneous catalysts has been reviewed and optimization parameters for maximum biodiesel production have been summarized.
