“…Previous studies on the hydrogenolysis of cyclohexane over the Ru/Al 2 O 3 catalyst show that Ru was less selective to desired n-hexane formation than Rh, and had a high cracking selectivity. 56 Kustov et al have also reported that the hydrogenolysis of cyclohexane was unselective over 1 wt% Ru/Al 2 O 3 as the reaction temperature reached 280 1C, which led to a 100 wt% yield of light products (C1-C3). 57 Moreover, the ring opening of MCP shows that C1-C5 cracking products were favored in the presence of 1.5 wt% Ru/SiO 2.…”

“…Very interestingly, the integration ratio for the peak at 1.26 ppm vs the peak at 0.86 ppm is almost equal to 1:1, which indicates a relatively clean ring opening process to produce n -hexane from cyclohexane. The reported , possible intermediate, methylcyclopentane was not observed by 2 H NMR. There are several possible reasons: the produced intermediate does not have any 2D atoms, which indicates a self-transformation; the methylcyclopentane is much more active than cyclohexane, which will accomplish the ring opening completely; and finally, the methylcyclopentane may not be the intermediate for the ring opening of cyclohexane.…”

In this study, a pyroprobe−deuterium ( 2 H) NMR system has been used to identify isotopomer products formed during the deuteration and ring opening of lignin model compounds. Several common model compounds for lignin and its upgraded products, including guaiacol, syringol, toluene, p-xylene, phenol, catechol, cyclohexane, methylcyclohexane, and methylcyclopentane, have been examined for selective ring opening. Similar pathways for upgrading of toluene and p-xylene has been found, which will undergo hydrogenation, methyl group elimination, and ring opening process, and benzene, cyclohexane, and methylcyclohexane have been found as major intermediates before ring opening. Very interestingly, the 2 H NMR analysis for the deuterium-traced ring opening of catechol on Ir/γ-Al 2 O 3 is almost identical to the ring opening process for phenol. The ring opening processes for guaiacol and syringol appeared to be very complicated, as expected. Benzene, phenol, toluene, cyclohexane, and methylcyclohexane have been determined to be the major products.

“…The opening of cyclohexane with the formation of n hexane was shown to proceed on oxide Rh , Ru , or Pt containing catalysts under certain conditions [32][33][34]. Among these metals, ruthenium is of special interest as it is the cheapest one.…”

Abstract⎯In recent years, the opening of the rings of aromatic and naphthene hydrocarbons has been con sidered as a way way of improving the quality of motor fuels. In gasolines, the opening of monocyclic com pounds like di and trialkylcyclohexanes allows the synthesis of high octane components (C 7 -C 10 iso paraf fins). In diesel fuels containing considerable amounts of bi and trinuclear polycyclic compounds such as derivatives of naphthalene (decaline), phenanthrene, and indane, this allows the synthesis of monocyclic compounds and alkanes, thus leading to a reduction in the freezing temperature of the fuel and, when obtain ing predominantly linear alkanes, to an increase in the cetane number. In this work, we conduct a brief anal ysis of accumulated data on the opening of cyclic compounds on oxide and zeolite supported catalysts.
