PROCESS FOR THE PRODUCTION OF ALCOHOLS BY CATALYTIC HYDROGENATION OF LEVULINIC ACID IN ONE STEP

摘要

The invention relates to a process for converting a feedstock comprising levulinic acid to monoalcohol in the presence of hydrogen, said process operating in one step, at a temperature of between 80 ° C and 250 ° C, at a pressure of between 0.5 and 20 MPa, and in the presence of a catalyst comprising a metal of groups 7 to 10 selected from platinum (Pt), ruthenium (Ru), iridium (Ir), rhenium ( Re), said metal being used alone and a support selected from titanium oxide (TiO2), zirconium oxide (ZrO2), and silica (SiO2), alone or in admixture. The process according to the invention makes it possible in particular to obtain butanol and preferably 2-butanol at a selectivity greater than 15 mol%,
