“…These kinds of catalysts have pulled in a lot of consideration from the scientic community because the uses of carbon as catalysts not only makes them reusable in the production process, but also greatly reduces the formation of the soap and increases the glycerol purity. 118 To date, different kinds of activated carbon-based catalysts have been developed and successfully exploited in biodiesel production, and some of them are briey discussed here (Table 18). Narowska et al 118 proposed the development of a novel carbon-based catalyst to replace the alkaline homogeneous catalyst as a solid catalyst, which has the potential to be reused multiple times, eliminating various limitations associated with other traditional catalysts.…”

“…Examples include a basic solid catalyst developed by the impregnation of KI on the calcined oyster shell, which was utilized in the transformation of soybean oil to FAME. [116][117][118][119] The authors reported that the impregnation and calcination increased the surface area to an extent of 32-fold, and therefore increased the catalytic activity. The main disadvantages of the catalyst are the reusability factor and higher loading of KI.…”

“…Green catalyst can be defined as solid catalyst derived from biological sources or biomass. Biodiesel has been successfully produced by using various biomass-derived catalyst including waste shell [12], animal bones biochars [13] and activated carbon [14]. The application of biomass-derived solid acid catalyst (SAC) is advantageous as it exhibits high catalytic activity due to their porous nature [15].…”

Homogeneous alkali catalyst produces soap as a by-product and generates a large amount of wastewater. This study investigates the potential of three types of biomass namely oil palm frond, coconut shell and groundnut shell to be developed as a solid acid catalyst for transesterification of waste cooking oil into biodiesel. The synthesis of solid acid catalyst is conducted by incomplete carbonization of biomass followed by sulfonation using concentrated sulfuric acid to incorporate the sulfonic group in the carbon body. The porosity of prepared catalyst was characterized by adsorption/desorption technique and surface acidity was evaluated by means of back titration method. Coconut shell showed the highest acid density of 0.51 mmol/g followed by groundnut shell and oil palm frond with 0.16 mmol/g and 0.12 mmol/g respectively. The biodiesel production was carried out at reaction conditions of methanol-to-oil ratio 20:1, reaction temperature 60 ºC, reaction time 6 h and catalyst loading 6 wt%. The highest biodiesel conversion was achieved using a coconut shell as a catalyst with 86.5%, followed by groundnut shell and oil palm frond. The use of solid acid catalyst derived from biomass could explores new market value for waste material while minimizing the solid waste production and further reduces cost and energy consumption in biodiesel production

<p>An ever-increasing energy demand and environmental problems associated with exhaustible fossil fuels have led to the search for an alternative renewable source of energy. In this context, biodiesel has attracted attention worldwide as an alternative to fossil fuel for being renewable, non-toxic, biodegradable, carbon-neutral; hence eco-friendly. Despite homogeneous catalyst has its own merits, currently, much attention has been paid to chemically synthesize heterogeneous catalysts for biodiesel production as it can be tuned as per specific requirement, easily recovered, thus enhance reusability. Recently, biomass-derived heterogeneous catalysts have risen to the forefront of biodiesel productions because of their sustainable, economical and eco-friendly nature. Further, nano and bifunctional catalysts have emerged as a powerful catalyst largely due to their high surface area and potential to convert free fatty acids and triglycerides to biodiesel, respectively. This review highlighted the latest synthesis routes of various types of catalysts including acidic, basic, bifunctional and nanocatalysts derived from different chemicals as well as biomass. In addition, the impacts of different methods of preparation of catalysts on the yield of biodiesel are also discussed in details.</p>
