Abstract

Bu bulus, gelistirilmis özelliklere sahip bir katalizörün hazirlanmasi için bir isleme iliskindir; bahsedilen islem, bir tasiyicinin seçilmesini, tasiyici yüzeyinde bulunan iyonlasabilir türlerin konsantrasyonunun azaltilmasini ve bir veya daha fazla katalik olarak reaktif metalin katalitik olarak etkili bir miktarinin tasiyici üzerine çökeltilmesini içerir. Bulus ayrica, bu islemle hazirlanan katalizörlere ve bu tür katalizörlerin, bir alken epoksitleme isleminde kullanilmasina da iliskindir. Örneklerde, iyonlasabilir türlerin konsantrasyonunun azaltilmasi, alfa alüminyum oksit tasiyicinin, kaynar suyla yikanmasiyla elde edilir. Daha sonra kurutulan tasiyiciya, bir promotor madde ve gümüs emdirilir.
