dc.descriptionWFC, waste from sugar beet processing, is a very active basic catalyst after calcination (900 ◦C, 2 h) in the transesterification of rapeseed oil under relatively mild reaction conditions (methanol-to-oil molar ratio of 9:1, temperature of 60 ◦C, and catalyst loading of 4–10%), ensuring a high oil conversion of 97.9% in 1 h. Therefore, it can be used as a lowcost and environmentally friendly source of CaO-based heterogeneous catalysts for producing biodiesel from rapeseed oil by a “green” process, reducing its costs. The high catalytic activity of the CFC catalyst is comparable to the activities of other CaO-based catalysts prepared from the WFC and natural sources. The biodiesel produced from rapeseed oil over the CFC had good fuel properties, which compile the specifications set by EN 14214. Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.en_US
dc.description.abstractA solid catalyst was prepared from waste filter cake (WFC) from a sugar beet processing plant and used, after calcination at 900 ◦C within 2 h, for biodiesel production from rapeseed oil and methanol. The calcined WFC (CFC) catalyst was characterized by XRF, FTIR, XRD, TGA/DTG, TPDe, TPD-CO2, SEM, N2 physisorption, and Hg porosimetry. The CFC is a CaO-based catalyst with a rigid, sustainable macroporous structure with the largest particles of 2.0 × 0.5 µm, a specific surface area of 7.3 m2/g, and a basicity of 0.27 mmol/g. It provides high conversion of 97.9% in 1 h at the methanol-to-oil molar ratio of 9:1, the temperature of 60 ◦C, and the catalyst loading of 10% of the oil mass. Its catalytic efficiency is comparable to the WFC-based nanocatalysts and CaObased catalysts from natural sources. CFC was reused twice with a negligible decrease in catalytic activity, ensuring a FAME content above 97% in 1 h. The biodiesel produced from rapeseed oil over the CFC catalyst has good fuel properties that fulfill most of EN 14214. Therefore, WFC is a promising source of a low-cost, highly active, basic, and environmentally friendly CFC catalyst, which could reduce biodiesel production costs. From this point of view, this catalyst has great potential for developing the process at the commercial level.en_US
