Summary:PROBLEM TO BE SOLVED: To provide a method for producing a propylene production catalyst which allows production quantities of ethylene, a paraffin component such as propane, and an aromatic component to be made smaller and which is excellent in propylene yield, a propylene/propane ratio and catalyst life.SOLUTION: The propylene production catalyst is used for producing propylene from one or more selected from the group consisting of methanol, dimethyl ether and 4-8C olefin and comprises a binder-less crystalline aluminosilicate molded body having 500-10,000 silicon/aluminum atomic ratio. The crystalline aluminosilicate contains a MFI crystal structure and/or a MEL crystal structure and is observed within a range of 3,715 cmto 3,735 cmby infrared spectroscopic analysis. A peak position of a hydroxyl group of the binder-less crystalline aluminosilicate molded body exists within another range of 3,725 cmto 3,735 cm. The method for producing the propylene production catalyst comprises a conversion step of converting a silicon component and an aluminum component into the crystalline aluminosilicate by contacting a raw material molded body with a saturated steam-containing atmosphere, which body consists of solid components containing the silicon component, the aluminum component and a structure directing agent component. 【課題】エチレン、プロパンなどのパラフィン成分、芳香族成分の生成量が少なく、プロピレン収率、プロピレン／プロパン比、触媒寿命に優れたプロピレン製造用触媒の製造方法を提供すること。【解決手段】メタノール、ジメチルエーテルおよび炭素数が４〜８のオレフィンからなる群から選択される１種または２種以上からプロピレンを製造するためのプロピレン製造用触媒であり、該触媒がケイ素／アルミニウム原子比が500〜10000であるバインダーレス結晶質アルミノシリケート成型体からなり、結晶質アルミノシリケートがMFI型の結晶構造及び／またはMEL型の結晶構造を含み、赤外分光分析で、3715cm-1から3735cm-1の範囲内に観察されるバインダーレス結晶質アルミノシリケート成型体の水酸基のピーク位置が、3725cm-1から3735cm-1の範囲内にあるプロピレン製造用触媒の製造方法であって、ケイ素成分、アルミニウム成分、及び構造規定剤成分を含む固体成分からなる原料成型体を、飽和水蒸気を含む雰囲気に接触させて、ケイ素成分及びアルミニウム成分を結晶質アルミノシリケートに変換する変換工程を含むことを特徴とするプロピレン製造用触媒の製造方法である。【選択図】なし
