Description
・ アセチレンのエチレンへの水素化は、少量のアセチレンからのエチレンの精製のためだけに用いられる。これらの方法は、エチレンを生成するための多量のアセチレンの水素化には使用できない。
・ アセチレン水素化からのエチレンの気相精製の従来のプロセスでは、これらの触媒の選択性が低いために、エチレンがある程度損なわれる。
・ Pd系触媒上での従来の気相アセチレン水素化の最中に、触媒の表面上でグリーンオイルが形成され、触媒が失活されてしまう。
・ 従来の気相水素化プロセスは、水素のアセチレンに対する比に関して制限されており、この比は、エチレンの選択性を高く維持するために特別に制御しなければならない。
触媒の調製
TiO2、SiO2などの必要量の担体を、ゲルまたは緻密な懸濁液の形態で調製した。次いで、その担体をPd(NO3)2またはPdCl2などの有機塩または無機塩、もしくはPd(NO3)4(OH)2などの組成物から、イオン吸着法によって、パラジウムで活性化させた。担持触媒を120℃で乾燥させ、次いで、40〜60メッシュの粒径に粉砕し、所望であれば、同じサイズの石英粒子で希釈し、最後に、反応前に1時間に亘り水素により還元させた。
本発明による方法を、10%のC2H2+20%のCH4+60%のH2と10%のCO2との混合物を用いて、4mmの内径を持つ金属製反応装置内で行った。反応装置に提供した触媒を、2時間に亘り350℃で水素により処理し、次いで、混合物を、230℃の温度で120cm3/分の流量で反応装置に供給した。反応装置は、非等温条件に維持され、反応装置の入口側で230℃、出口側で90℃の温度プロファイルを有した。反応装置内の圧力は大気圧であった。
実施例2において、異なる温度での120cm3/分の流量による、触媒が提供されたウォッシュコートされた金属製反応装置内のアセチレン転化が示されている;供給組成物:10%のC2H2+60%のH2+30%のCH4。
実施例3において、固定床触媒が提供された石英製反応装置内のアセチレン転化に対する流量および温度の影響が示されている。供給組成物:10%のC2H2+60%のH2+30%のCH4、反応時間:40時間。
実施例4において、230℃での固定床触媒が提供された石英製反応装置内のアセチレン転化の結果が示されている;流量120cm2/分;供給組成物:10%のC2H2+60%のH2+30%のCH4;反応時間:60時間。
実施例6において、60℃での固定床触媒が提供された石英製反応装置内のアセチレン転化の結果が与えられている;流量:500cm3/分;触媒:0.02g;供給組成物:10%のC2H2+60%のH2+30%のCH4;反応時間:60時間。
