Catalytic performance and characterization of Cs–Ca/SiO2–TiO2 nanocatalysts for biodiesel production

“…Increasing the surface significantly increases the reactivity of the nanoparticles, since the number of molecules or atoms existing on the surface are very high compared to the number of atoms or molecules in the sample bulk. The heterogenization of palladium catalysts on renewable supports is very important from both economic and environmental points of view …”

The palladium metal nanoparticles doped on the modified chitosan nanofibers with 2-aminobenzaldehyde (CSNFs-2-ABÀ Pd (0)) were thoroughly characterized and applied as a novel heterogeneous catalyst in Heck and Suzuki CÀ C coupling reactions. This catalyst is exceptionally simple to handle and ecologically safe and temperate. The catalyst was essentially reused from the reaction mixture and reused sequential five times with low leakage. CSNFs-2-ABÀ Pd (0) was characterized using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and Fourier transform infrared.

“…The use of heterogeneous nanomaterials as a catalyst offers an innovative pathway for production and exploitation of biodiesel. Other oxide catalysts such as Cs-Ca/TiO 2 -SiO 2 [19], SiO 2 [20], ZnO [21], Ca/Sn [22], MgO [23] KF/CaO [24], Cd/Sn [25],SiO 2 /TiO 2 [26] and so forth were also used in an effective manner. The catalysts, after the reaction, maintain their physical and chemical properties, and it can be reused without significant deactivation [14].…”

Biodiesel is considered as an alternative fuel which can replace the traditional fuels easily with its less hazardous effects and economical pricing. This study compares an ultrasonic‐assisted catalytic transesterification using ZnO nanocatalyst for waste cooking oil (WCO) with the conventional stirring method. The structural and morphological characterizations of prepared catalysts were done by XRD and FESEM with EDX methods. The effect of reaction parameters such as oil to methanol ratio, catalyst amount and reaction time was investigated to optimize the transesterification conditions. GC/MS and FTIR analysis have been carried out to identify and confirm the presence of fatty acid methyl esters (FAME) under optimum conditions. The FAME conversion yield up to 96% under ultrasonication method was calculated. Two important fuel properties like density and viscosity were analyzed and compared with the standard biodiesel. These studies provided the clear evidence that WCO can be employed as a substantial source of biodiesel as fuel in diesel engines. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1176–1182, 2018
