Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Elsevier, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
Biodiesel production from rapeseed oil over calcined waste filter cake from sugar beet processing
(Elsevier, 2022)
A 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) ...
Kinetics and optimization of biodiesel production from rapeseed oil over calcined waste filter cake from sugar beet processing plant
(Elsevier, 2023)
A low-cost, highly active CaO-based catalyst was prepared from waste filter cake (WFC) from a sugar beet processing factory by calcination in air at 900 °C for 2 h, referred to as the calcined filter cake (CFC). It was ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
