ALUMINA CARRIER
To provide an alumina carrier to be used for a catalyst for gas phase reaction, highly activating catalytic reaction, and reduced in a yield of by-products, and to provide a gas reaction catalyst carried with a metallic compound on the alumina carrier.SOLUTION: An alumina carrier to be used for a catalyst for gas phase reaction has a cylindrical shape having at least one penetrating hollow hole. The alumina carrier is such that: a BET specific surface area is 140-280 m2/g; a volume (total pore volume) of pores having a pore diameter of 15 nm or more and 20,000 nm or less, measured by a mercury press-in method is 0.04-0.15 cm3/g; a volume of pores having a pore diameter of 1,000 nm or more and 20,000 nm or less is 0.02 cm3/g or less; and a tapping bulk density is 620-780 g/L.SELECTED DRAWING: None
【課題】気相反応用の触媒に使用され、触媒反応が高活性になり、且つ副生成物の収率が低減されるアルミナ担体、さらには、当該アルミナ担体に金属化合物を担持させた気相反応触媒を提供する。【解決手段】気相反応用の触媒に使用するアルミナ担体において、貫通する中空孔を少なくとも１つ有する筒状形状を有しており、ＢＥＴ比表面積が１４０～２８０ｍ２／ｇであり、水銀圧入法で測定した細孔直径１５ｎｍ以上２００００ｎｍ以下の細孔の容積（全細孔容積）が０．０４～０．１５ｃｍ３／ｇであり、且つ細孔直径１０００ｎｍ以上２００００ｎｍ以下の細孔の容積が０．０２ｃｍ３／ｇ以下であり、タッピング嵩密度が６２０～７８０ｇ／Ｌであること、を特徴とするアルミナ担体。【選択図】なし
