Alternative energy is a future necessity to society regarding the restricted supply of fossil fuel. Considering this, the formation of a liquid fuel product from the degradation of lignin, a component of biomasses and plentiful “biowaste”, would be a major advance. Previously it was shown that porous metal oxides (PMO) containing copper, aluminum, and magnesium were promising catalysts in the process of hydrodeoxygenation of lignin.  It was proposed that the reactivity of these catalysts was enhanced by the addition of Lewis acidic elements. Thus, the selectivity of such new prepared mixed metal oxides was investigated. Each reaction was conducted at 300°C with supercritical methanol as the media. Under these conditions it was found that copper gallium oxide fully converts dihydrobenzfuran (DHBF), a model compound of lignin, into ethylbenzene, an energy rich product, and 2-ethyl-cyclohexanol. Copper oxide and a mixture of copper oxide with titanium oxide showed good transformation of DHBF to ethylbenzene, cyclohexanol, methylcycolhexanol, 2-ethyl-cyclohexanol, and 2-ethyl-phenol. Furthermore, 5% copper alumina silica, copper praseodymium oxide and copper samarium oxide displayed favorable conversion of DHBF to phenol.
