Document Type and Number:
Japanese Patent JP3636206
Kind Code:
B2
Abstract:
In one embodiment,the invention relates to a formed copper chromite catalyst prepared from a blend comprising from about 20 to about 80% by weight of copper chromite and from about 20 to about 80% by weight of at least one extrudable inorganic binder material wherein the catalyst has a surface area of from about 20 to about 225 m2/g, and the total pore volume of the pores in said catalyst having a diameter of up to about 95,000 ANGSTROM is between about 0.35 to about 1 cc/g. In another embodiment, the invention relates to a process for preparing the formed copper chromite catalyst of the invention, and the process comprises (A) preparing a blend comprising from about 20 to about 80% by weight of copper chromite, from about 20 to about 80% by weight of at least one extrudable inorganic binder material, from about 1 to about 10% by weight, based on the weight of the binder, of a peptizing agent, and sufficient water to form an extrudable blend; (B) extruding the blend to form an extrudate; and (C) calcining the extrudate. The invention also relates to a process for hydrogenating aldehydes, ketones, carboxylic acids and carboxylic acid esters with catalysts of the type described.
