Abstract

The present development is a method for the selective conversion of furfural to 2-methylfuran (2-MF) using a catalyst comprising non-toxic and non-noble metals and wherein the method requires relatively mild processing conditions. The catalyst comprises copper metal particles, used alone or in combination with cobalt, nickel, manganese, ruthenium, gallium, zinc, aluminum or a combination thereof, on a nanowire support. The catalyst is stable in liquid phase reactions and in the presence of water. The present development also includes a process for producing the catalyst.

Claims13

Dependent claims

A method for the selective conversion of furfural to 2-methylfuran (2-MF) comprising:

(a) providing a catalyst comprising copper metal particles and a metal oxide nanowire support wherein the catalyst is formed by plasma oxidation of a paste formed by mixing precursors of the copper metal particles with the metal oxide nanowire support;
(b) loading a reactor with the catalyst;
(c) reducing the catalyst;
(d) cooling the reactor to room temperature;
(e) feeding a hydrogen source and furfural into the reactor;
(f) heating the reactor to a predetermined temperature between 180° C. and 250° C.;
(g) pressuring the reactor to a predetermined pressure of less than 300 psi;
(h) allowing the furfural to react with the hydrogen source in the presence of the catalyst for a reaction time of less than 12 hours;
and,
(i) recovering 2-methylfuran from the reactor.
