The activity of nanopowder and mesoporous titanium catalysts for the analysis of fatty acids in triglycerides by pyrolysis methylation with dimethyl carbonate

Analytical study on the pyrolytic behaviour of cellulose in the presence of MCM-41 mesoporous materials

“…Sn-MCM-41 gave a broad (1 0 0) diffraction peak, suggesting a partial disturbance of the hexagonal ordering, probably due to the larger ion radius of Sn 4+ with respect to Si 4+ . In fact, the XRD pattern of Sn-MCM-41 evidenced the occurrence of tin oxide as an additional phase, likely formed from excess Sn not included into the pores, similarly to what observed for Ti-MCM-41 [20].…”

“…The synthesis of MCM-41 mesoporous materials was performed under mild conditions as previously described [20]. In a typical procedure, a weighed amount of metal salt (4.4 mmol of metal) was added into 120 ml of an aqueous solution of CTAB (2.4 g) until complete dissolution.…”

Recent applications in analytical thermochemolysis

“…Fabbri's group also tried nanopowder and mesoporous titanium catalysts with dimethyl carbonate for the analysis of fatty acids in triacylglycerols [63]. TiSiO 4 as a catalyst compared to some other nanopowder metal oxides produced the highest yield of fatty acid methyl esters.…”

Catalytic effect of tin oxide nanoparticles on cellulose pyrolysis

“…This behavior of nano SnO 2 can be explained by accelerated primary and secondary decomposition reactions of hazelnut shell due to the nano size and large external surface area of the nanoparticles [21]. Nowadays, it has been seen an increase in papers about metal oxide catalyzed pyrolysis [17,[20][21][22][23][24][25][26][27][28][29][30][31][32] in the literature and also some of them about bulk metal oxides [17,23,[25][26][27][28]32]. The aim of this study is, using SnO 2 nanoparticles as a catalyst in the conversion of cellulose which is the major component of biomass (40-60% (w/w)) [ determining the effects of products distribution, with this respect, nano SnO 2 was used as a catalyst for the pyrolysis of cellulose to test whether they had the capability to upgrade the properties of pyrolytic oil and gaseous fractions.…”
