PURPOSE:To obtain a fixed bed catalyst having large contact area between a fluid and the catalyst, and capable of smoothly passing the fluid through and dispersing it into the catlyst, by using a pack of bulky activated carbon fibers are a carrier. CONSTITUTION:Activated carbon fibers impregnated with an activated component, such as Ru, of a catalyst entwined each other, for example, felt of acrivated carbon fibers is used for forming an intended fixed bed catalyst. This felt persists <=0.2g/cm<3> at >=1kg/cm<3> compression force. Therefore, even if a fluid is forced to flow by pressure, it causes no appreciable deformation, retaining bulkiness, and spaces among the fibers, permitting smooth flow of the fluid with low resistance. As a result, large contact area between the fluid and the catalyst, and large contact area between liquid wetting the fibers and gas can be retained stably. In addition, an amt. of activated component of the catalyst to be held on the carrier is usually 0.01-10wt%. |
