Abstract
A lignocellulosic starting material can be converted into an aqueous phase and a hydrocarbon phase in a one-step process by subjecting a mixture of the lignocellulosic starting material, an amorphous and unsupported sulfided nickel-molybdenum catalyst, and optionally a co-feed, to not less than a stoichiometric amount of hydrogen, elevated pressure and a temperature in the interval of 350-450° C. A novel catalyst for use in said process and a method for its production are also disclosed.
Claims16
A process for the conversion of a lignocellulosic starting material into an aqueous phase and a hydrocarbon phase, characterized in that the lignocellulosic starting material, an amorphous and unsupported sulfided nickel-molybdenum catalyst, and optionally a co-feed, are mixed and subjected to not less than a stoichiometric amount of hydrogen, elevated pressure and a temperature in the interval of 350-450° C., producing an aqueous phase and a hydrocarbon phase.
A nickel-molybdenum sulfide catalyst, characterized in that said catalyst has the empirical formula with regard to molybdenum (Mo), nickel (Ni) and sulfur (S):
- MoxNiySz
- wherein x=1, 0.1<y<0.2 and z≤1.0.
