catalyst of copper cromito esuo for use in the preparation of alcohol from furfural by furfurilico procedure or by a discontinuous process in liquid phase.

摘要

A copper chromite catalyst having improved activity is prepared by forming a basic copper ammonium chromate complex in a known manner. The complex is decomposed by sintering at temperatures near 300 DEG C. to yield a copper chromite catalyst of improved activity. The copper chromite catalyst is especially useful in liquid phase production of furfuryl alcohol from furfural by hydrogenation. The hydrogenation reaction takes place at low pressure, e.g. under 30 atmospheres, due to the increased activity of the catalyst.
