Trends in Biodiesel Production: Present Status and Future Directions

Potential of Virginia-type peanut (Arachis hypogaea L.) as feedstock for biodiesel production

“…Thus, the results obtained in this study are very attractive, because when is analyzed the profile of the used feedstocks for biodiesel production in Brazil as in the case of soybeans, that is the most used (ANP, 2015; Perez et al, 2014), their oil content is less than half of the peanut oil content. This opens a good prospect in relation to the potential of this oilseed as alternative feedstock for biodiesel production mainly in the southeastern region, where the peanut production is considered to be the highest in Brazil (CONAB, 2014).…”

Biodiesel production from heterogeneous catalysts based K2CO3 supported on extruded γ-Al2O3

“…Particularly, biodiesel, which is the focus of this work, is very attractive because it can be used in diesel engines without any modification and, moreover, can be produced by chemically and biochemically route. The world production of biodiesel in 2017 was 30.7 billion liters whose global ranking is led by transesterification using homogeneous alkaline catalyst such as KOH or NaOH or their corresponding alkoxide (CH 3 ONa + or CH 3 OK + ) and methanol as reactant alcohol [2].…”

Extruded Catalysts with Magnetic Properties for Biodiesel Production

“…Basically, in Brazil, the conventional biodiesel production at industrial scale is carried out by chemical transesterification by homogeneous catalysis and using methanol as reactant alcohol although there are some plants that produce ethanolic biodiesel [3]. e predominant feedstock is soybean oil, which corresponds to 64.84% of the national production, followed by beef tallow with 15.50% and finally other raw materials, such as pork fat, palm oil, and various fatty sources which represent 19.66% [1].…”

In this scenario, attention must be paid to two important aspects in this conventional process that lead to technological and/or environmental problems which have already been reported: (a) the use of homogeneous catalysts and (b) the use of methanol as a reactant alcohol [3,4]. In the first case, the catalyst solubilizes in the reaction medium preventing its reuse and, therefore, this makes the process more expensive.…”
