“…Recently, immobilized ionic liquid catalysts are also tested for the glycerolysis of urea. For ionic liquids catalysts, as always, the length of the carbon chains and the sterical structure had significant effects on their catalytic performances besides their inherent nature of active sites (364,365,366,367,369). Remarkably, the use of a co-catalyst system consisting of inorganic oxides and immobilized ionic liquids significantly enhanced the catalytic activity (369).…”

Nevertheless, to put the glycerolysis of urea into use in industry, in addition to the catalysts, the separation and purification of glycerol carbonate are also critical, yet these are rarely reported (350,364,370).…”

The article underlines and discusses the state-of-the-art accomplishments in the catalytic conversion of glycerol (1,2,3-propanetriol) to fuels and value-added chemicals in the past five years (2008)(2009)(2010)(2011)(2012). The reactions include steam reforming, aqueous-phase reforming, hydrogenolysis, oxidation, dehydration, esterification, etherification, carboxylation, acetalization, and chlorination. Typical products are hydrogen, propanediols, dihydroxyacetone, glyceric acid, acrolein, glyceride, polyglycerol, glycerol carbonate, acetals, ketals, and epichlorohydrine. Recent studies on the catalysts, reaction conditions, and possible pathways are primarily discussed. They indicate that major breakthroughs are achieved by the use of multifunctional catalysts, process intensification and integrated reactions. Literature survey suggests that future work on the catalytic conversion of glycerol for commercial goals particularly requires new catalysts, innovative reactor engineering, and close multidisciplinary partnership.

“…Of particular interest is to immobilize ILs through heterogenization of ILs onto suitable solid supports like organic polymers and inorganic materials [116,117]. By the reaction of imidazole with alkoxylated Merrifield peptide resin (MPR), ILs incorporated on the MPR catalysts MPR-ILs were successfully developed [118]. MPR-ILs with longer alkyl chains and fewer sterically hindered counteranions demonstrated better catalytic performance in GC synthesis, giving 80.9% e Mg-Al hydrotalcite catalyst was investigated in GC production, and the hydrotalcite-like compounds containing Mg, Zn, and Al metals showed an excellent catalytic performance [97].…”

Versatile polymers with highly adjustable characteristics and a broad range of applications are possibly developed owing to the contemporary industrial polymerization techniques. However, industrial production of large amounts of chemicals and polymers heavily depends on petroleum resources which are dwindling and unsustainable. Of particular interest is to utilize sustainable and green resources for the manufacture of polymeric materials. The efficient transformation of bio-glycerol to the relevant functional derivatives are being widely investigated owing to the increasing demand for enhancing the value of glycerol manufactured by biodiesel and oleochemical industries. With respect to glycerol-based polymer chemistry and technology, considering the economy and environmental benefits, using effective catalysts for the selective transformation of bio-glycerol and urea into glycerol carbonate (GC) as a polymer monomer is of great significance. In this review, recent studies on GC synthesis involving the catalysts such as zinc, magnesium, tungsten, ionic liquid-based catalysts, reaction conditions, and possible pathways are primarily described. Some critical issues and challenges with respect to the rational development of heterogeneous catalytic materials like well-balanced acid-base sites are also illustrated.

“…Furthermore, our biosolids-based catalyst is comparable with cobalt nanoparticles supported on ZnO [37], and zinc-tin catalysts [38] that reached conversion around 69% at 150 °C. Other expensive catalysts such as Au and Pd nanoparticles [39], ionic liquids [40] or lanthanum oxides [41] could be used achieving conversion up to 84% and selectivity around 87%, but they require several steps for preparation and high control of reaction conditions. Nevertheless, a key advantage to our biosolids-based catalyst is the fact that it can be generated from a negative-value waste stream using a thermal treatment that has also been shown to drastically improve settling rates [31].…”

Although thermal hydrolysis of digested biosolids is an extremely promising strategy for wastewater management, the process economics are prohibitive. Here, a biosolids-based material generated through thermal hydrolysis was used as a catalyst for urea glycerolysis performed under several conditions. The catalytic system showed remarkable activity, reaching conversion values of up to 70.8 ± 0.9% after six hours, at 140 °C using a catalyst/glycerol weight ratio of 9% and an air stream to remove NH3 formed during the process. Temperature played the most substantial role among reaction parameters; increasing temperature from 100 °C to 140 °C improved conversion by 35% and glycidol selectivity by 22%. Furthermore, the catalyst retained good activity even after the fourth catalytic run (conversion rate of 56.4 ± 1.3%) with only a slight decrease in glycidol selectivity. Thus, the use of a biosolids-based catalyst may facilitate conversion of various glycerol sources (i.e., byproduct streams from biodiesel production) into value-added products such as glycidol, and may also improve the economic feasibility of using thermal hydrolysis for treatment of biosolids.
