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.

“…%of catalyst, reaction temperature of 65°C and reaction time of 2.5 hr. Deng et al (2011) observed that hydrotalcite-derived particles with Mg/Al molar ratio of 3:1could be an effective method for the production of biodiesel from Jatropha oil with a 95.2% yield after 1.5 hrs at ultrasonic conditions. Reddy et al (2006) achieved a 99% biodiesel yield from soybean oil in room temperature by using nanocrystalline calcium oxides as a catalyst.…”

HIGHLIGHTSSignificant improvements in biomass conversion using nanocatalysts. Feasibility of utilization milder operating conditions by using nanocatalysts compared to the bulk catalysts. The role of nanocatalysts to overcome some challenges in biomass conversion, improving the products quality. GRAPHICAL ABSTRACTProducts from nanocatalytic conversion of biomass The world's increasing demand for energy has led to an increase in fossil fuel consumption. However this source of energy is limited and is accompanied with pollution problems. The availability and wide diversity of biomass resources have made them an attractive and promising source of energy. The conversion of biomass to biofuel has resulted in the production of liquid and gaseous fuels that can be used for different means methods such as thermochemical and biological processes. Thermochemical processes as a major conversion route which include gasification and direct liquefaction are applied to convert biomass to more useful biofuel. Catalytic processes are increasingly applied in biofuel development. Nanocatalysts play an important role in improving product quality and achieving optimal operating conditions. Nanocatalysts with a high specific surface area and high catalytic activity may solve the most common problems of heterogeneous catalysts such as mass transfer resistance, time consumption, fast deactivation and inefficiency. In this regard attempts to develop new types of nanocatalysts have been increased. Among the different biofuels produced from biomass, biodiesel has attained a great deal of attention. Nanocatalytic conversion of biomass to biodiesel has been reported using different edible and nonedible feedstock. In most research studies, the application of nanocatalysts improves yield efficiency at relatively milder operating conditions compared to the bulk catalysts. ARTICLE INFO ABSTRACT
