Abstract
Foraminate nickel catalysts (for use in the hydrogenation of furfural and furfuryl alcohol) may be prepared by alloying nickel with a metal which is more soluble in acid or alkali, converting the alloy into granular form, and treating the granules with acid or alkali so as to remove a part of the alloying metal. Suitable alloying metals are aluminium, zinc and silicon. Catalysts so prepared from nickel-aluminium and nickel-silicon alloys may be reactivated by treatment with a current of hot dilute caustic soda solution passed preferably in the opposite direction to the flow of the materials during the reaction. Examples are given in which furfural and a mixture thereof with tetrahydrofurfuryl alcohol are hydrogenated by passage through a tube packed with alternate layers of foraminate nickel-aluminium catalyst and silicon chips. Specifications 570,843 and 608,565, [Group IV (b)], are referred to.ALSO:Tetrahydrofurfuryl alcohol is prepared from furfural or furfuryl alcohol by a liquid-phase hydrogenation process in which the starting material and hydrogen are caused to flow at a raised temperature and pressure past a foraminate nickel catalyst. The process may be effected continuously at 50-200 DEG C. and 50-500 atm. pressure, and a part of the reaction product may be returned to the reaction zones. Hydrogen substantially free from carbon monoxide, sulphur and ammonia is preferably used, but the process may be effected either under anhydrous conditions or in the presence of water. An alkali, such as sodium carbonate, may also be present. Examples are given in which furfural and a mixture thereof with tetrahydrofurfuryl alcohol are hydrogenated by passage through a tube packed with alternate layers of foraminate nickel-aluminium catalyst and silicon chips. The Provisional Specification states that cobalt may also be used as the catalyst. Catalytic agents, preparation and treatment of. Foraminate nickel catalysts may be prepared by alloying nickel with a metal which is more soluble in acid or alkali, converting the alloy into granular form, and treating the granules with acid or alkali so as to remove a part of the alloying metal. Suitable alloying metals are aluminium, zinc and silicon. Catalysts so prepared from nickel-aluminium and nickel-silicon alloys may be reactivated by treatment with a current of hot dilute caustic soda solution passed preferably in the opposite direction to the flow of the materials during the reaction. Specifications 570,843, [Group III], and 608,565 are referred to.
