In this work, nickel-copper-containing alloy catalysts with different contents of nickel oxide were prepared and used in the furfural hydroconversion to 2-methylfuran and furfuryl alcohol. The most active catalyst (7Ni19Cu61Fe13Al) was chosen. We selected the reaction conditions, providing a high yield of 2- methylfuran (81 wt. %) at 100 % furfural conversion in a batch reactor: T = 200 C, P(H2) = 5:0 MPa, reaction time 4 h. The selected catalyst was studied by a complex of physicochemical methods; we determined the phase and surface composition, the morphology of the active component, and the possible cause of catalyst deactivation during the reaction due to the irreversible sorption of reactants and reaction products, as well as their polymeric structures on the catalyst surface. We have demonstrated the possibility of obtaining 2- methylfuran for the 7Ni19Cu61Fe13Al catalyst with a selectivity of 70 % at 87 % conversion of furfural in a flow-type reactor without solvent at LHSV = 6 h-1, T = 200 C, P(H2) = 5:0 MPa.

Сплавные никель-медьсодержащие катализаторы с различным содержанием оксида никеля были приготовлены и протестированы в процессе гидроконверсии фурфурола до 2-метилфурана и фурфурилового спирта. Выбран наиболее активный катализатор (7Ni19Cu61Fe13Al), а также подобраны условия реакции, обеспечивающие высокий выход 2-метилфурана (81 мас. %) при 100 % конверсии фурфурола в реакторе периодического действия: Т = 200 °С, Р(Н2) = 5,0 МПа, время реакции 4 ч. Выбранный катализатор исследован комплексом физико-химических методов, определены его фазовый и поверхностный составы, морфология активного компонента, выявлена причина дезактивации катализатора в ходе реакции, возникающая за счет необратимой сорбции реагентов и продуктов реакции, а также продуктов их взаимодействия на поверхности катализатора. Показана возможность получения 2-метилфурана в присутствии катализатора 7Ni19Cu61Fe13Al с селективностью 70 % при 87 % конверсии фурфурола в проточном реакторе без растворителя при LHSV = 6 ч-1, 200 °С, давлении водорода 5 МПа.
