The present invention describes a procedure for the production of liquid fuel having a content high in alkanes and low in oxygenated compounds, comprising as a minimum: —a first step of alkylation of 2-methylfuran (commonly denominated Sylvan) with a furan alcohol 2 having the formula: (2), wherein R
1
is H or an aliphatic or aromatic or heteroaromatic moiety, R
2
is H or an aliphatic or aromatic or heteroaromatic moiety, and R
3
is H, hydroxymethyl or an aliphatic or aromatic or heteroaromatic moiety, in the presence of a catalyst, —a second step of hydrogenation and dehydration of the compound obtained in step 1 in the presence of hydrogen, utilising suitable hydrogenation and dehydration catalysts.

through catalytictransferhydrogenation of furfural in the liquid phase has been investigated over a Ru/Ccatalyst in the temperature range of 120–200 °C using 2-propanol as a solvent. It has been found that furfuralhydrogenation produces furfuryl alcohol, which undergoes hydrogenolysis to methyl furan. Small amounts of furan and traces of tetrahydrofurfuryl alcohol are also produced via furfural decarbonylation

effect of alcohol hydrogen donor on methyl furan production through catalytic transfer hydrogenation of furfural in the liquid phase has been investigated over a mildly calcined Ru/C catalyst in the temperature range of 110–200 °C. It has been found that several parameters contribute to furfural hydrogenolysis, including alcohol dehydrogenation activity, solvent properties, as well as sidereactions such
