    Abstract: 本発明は、海水式気化器用海水供給装置に関し、海水式気化器で散水された海水を集水部に集めて集水した後、海水放流管部と海水循環管部で前記海水式気化器に再び再供給することにより、海水式気化器の作動時、海水式気化器に供給される海水の温度を海洋生物が生息しにくい温度以下に維持させることで、海水式気化器の作動時に供給される海水に塩素溶液の注入を必要としないようにし、近隣海の汚染を防止する。

    Abstract: PROBLEM TO BE SOLVED: To provide a mixed catalyst used for producing dimethyl ether, which is used for producing dimethyl ether selectively at a high conversion rate of carbon monoxide from a gaseous mixture containing hydrogen, carbon monoxide and carbon dioxide.
    SOLUTION: The mixed catalyst comprises a methanol synthesis catalyst which is produced from a sodium carbonate solution and a metal nitrate solution formed by adding a promoter including at least one selected from Mg, Zr, Ga, Ca and the oxide thereof to a main catalyst which is a solution where a copper nitrate solution, a zinc nitrate solution and aluminum nitrate solution are mixed, and a dehydration catalyst which is formed by mixing aluminum phosphate (AlPO
    4 ) with gamma alumina. A ratio of the main catalyst to the promoter in the methanol synthesis catalyst is in a range of 19 to 99. A ratio of aluminum phosphate to gamma alumina in the dehydration catalyst is in a range of 1:0.82 to 1:1.22. A mixing ratio of the methanol synthesis catalyst to the dehydration catalyst is in a range of 1:0.4 to 1:0.65.
