Biodiesel, as renewable and biological origin alternative diesel fuel, has been receiving a lot of concern throughout the world due to the energy needs and environmental awareness. However, at present, it is not economically feasible to use food-grade vegetable oils to produce biodiesel because of the surge in feedstocks price. Much attention has been devoted to the application of lower-cost feedstocks to produce biodiesel. This paper provided a comprehensive review of biodiesel production from lower-cost non-edible oil sources, such as waste cooking oil (WCO), grease, soapstock, Jatropha oil, and algae. The engine performances of biodiesel produced from these feedstocks were further evaluated. This review also investigated the various applications for the value-added products from glycerol, the byproduct of biodiesel. Moreover, the challenges in terms of different feedstocks and by-product applications were further pointed out.

“…It finds several applications in different industrial sectors, especially as a polar high boiling solvent or intermediate in organic syntheses, monomer in the synthesis of polycarbonates, polymeric materials in the plastic field [19]. It is also used as a precursor in biomedical applications, a protection group in the carbohydrates chemistry [20], a component in membranes for gas separation, in the synthesis of polyurethanes [21] and in the production of surfactants [22].…”

Understanding the Role of Tantalum in Heteropoly Tungstate Catalysts for the Synthesis of Glycerol Carbonate from Glycerol and Urea

Tantalum exchanged tungstophosphoric acid (Ta x TPA) catalysts were prepared and studied for the synthesis of glycerol carbonate from glycerol and urea. These catalysts were characterized by FT-IR, X-ray diffraction, Laser Raman, pyridine adsorbed FT-IR and temperature programmed desorption of ammonia. The characterization results indicate that the Keggin ion structure of tungstophosphoric acid (TPA) is intact. The activity towards the synthesis of GC over the Ta x TPA catalysts depended on the number of Ta 5? ions exchanged in the secondary structure of heteropoly tungstate. Presence of Ta in TPA leads to the generation of Lewis acidic sites. Catalysts with partially exchanged Ta with the protons of TPA showed high activity due to the presence of both Brønsted and Lewis acidic sites. Different reaction parameters such as reaction temperature, glycerol to urea molar ratio and catalyst loading were studied and optimum conditions were established. These catalysts exhibited reusability. Graphical Abstract1 2 3 4 5 0 10 20 30 40 50 60 70 80 90 100 Selectivity (%) Conversin (%) Reaction time (h) 0 10 20 30 40 50 60 70 80 90 100

“…It has been investigated as a novel component of gas-separation membranes, polyurethane foams [6], surfactants [7], coatings, paints, and detergents, and as a nonvolatile reactive solvent for several types of materials. GC could thus serve as an inexpensive source of new polymeric materials for the production of polycarbonates and polyurethanes [8].…”

Catalytic performance of polymer-supported ionic liquids in the synthesis of glycerol carbonate from glycerol and urea

et al. 2011

View full text Add to dashboard Cite

Ionic liquids (ILs) immobilized onto a structurally modified Merrifield peptide resin (MPR) were prepared through the reaction of imidazole with alkoxylated MPR. Elemental analysis and scanning electron microscopy (SEM) observations showed that the immobilized IL groups were effectively incorporated on the support. The MPR-supported ILs (MPR-ILs) proved to be effective heterogeneous catalysts for the synthesis of glycerol carbonate (GC) from glycerol and urea. MPR-ILs with longer alkyl chain linkers and fewer sterically hindered counteranions resulted in higher conversion of glycerol. High temperature, high degree of vacuum and the presence of zinc oxide co-catalyst were favorable for glycerol conversion. The MPR-ILs could be reused in up to three consecutive runs without significant loss of their catalytic activity.
