Title:
COPPER-BASED CATALYST PRECURSOR, METHOD FOR MANUFACTURING SAME, AND HYDROGENATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/034879
Kind Code:
A1
Abstract:
Provided are a copper-based catalyst precursor capable of obtaining a high conversion ratio and high selectivity in isomerization reaction of β,γ-unsaturated alcohol moieties, a method for manufacturing the copper-based catalyst precursor, and a hydrogenation reaction in which the copper-based catalyst precursor is used. Specifically, there are provided: a copper-based catalyst precursor obtained by firing, at 500 to 1000°C, a mixture containing copper, iron, aluminium, and calcium silicate, the atomic ratio of iron and aluminum relative to copper ((Fe + Al)/Cu) being 1.71 to 2.5, the atomic ratio of aluminum relative to iron (Al/Fe) being 0.001 to 3.3, and the calcium silicate content being 15 to 65 mass%; and a hydrogenation method in which the copper-based catalyst precursor is used.
