To obtain a catalyst capable of advantageously performing the hydrogenation, dehydrogenation and hydrocracking of an organic and inorganic body by forming the catalyst only from a catalytic alloy and specifying total pore volume or the like in a molded metal-fixed bed catalyst containing a catalytic metal, an alloy component capable of eluting and if necessary, a co-catalyst.
In the metal-fixed bed catalyst, the catalyst is formed only from the catalytic alloy, attains 0.1-0.6 ml/g total pore volume and a part of an outside layer 0.1-2.0 mm thick from the surface is activated by the elusion of the alloy component capable being completely or partially eluted. And as the preferable catalyst component, nickel, cobalt, copper or iron and as the alloy component capable of eluting, aluminum, zinc or silicon is used. And the weight ratio of the catalyst metal and the alloy component capable of being eluted is setted to (30:70) to (70:30). Further s the co-catalyst, ≤15 wt.% element, such as chromium, iron, cobalt, tungsten, molybdenum, titanium per the weight of the catalytic alloy is added.
