Autor: Zs. Koppány, Zoltán Schay, István E. Sajó, Andrea Beck, Anita Horváth, O. Geszti, László Guczi, Gy. Stefler

Publikováno v: Topics in Catalysis. 44:115-121

Bimetallic AuPd catalysts were prepared by deposition of bimetallic aqueous sols formed in different ways: (i) co-reduction of the precursor Au and Pd ions by Na-citrate/tannic acid mixture, (ii) reduction of Au(III) ions onto preformed Pd sol, and (

Promoter Effect of Pd in Hydrogenation of 1,3-Butadiene over Co-Pd Catalysts

Autor: A. Sarkany, Z. Zsoldos, L. Guczi, Gy. Stefler, Joe W. Hightower

Publikováno v: Journal of Catalysis. 157:179-189

Addition of a second metal or metal oxide often improves the selectivity of a supported catalyst for the hydrogenation of 1,3-butadiene impurities in commercial n -butene streams. This research has explored the effect of adding Pd to cobalt supported

Participation of support sites in hydrogenation of 1,3-butadiene over Pt/Al2O3 catalysts

Autor: Gy. Stefler, Joe W. Hightower, Antal Sárkány

Publikováno v: Applied Catalysis A: General. 127:77-92

The effect of acidic sites on activity and product selectivity has been investigated in 1,3-butadiene hydrogenation over platinum catalysts prepared with high purity Al2O3 supports (Condea SB, Woelm N, Degussa Alumina C, ICN-N). Degassing the reduced

Hydrogenation of 1,3-butadiene over catalysts prepared from amorphous Pd2Ni50Nb48 ribbon: Effect of self-poisoning on competitive adsorption

Autor: Antal Sárkány, Gy. Stefler, Zoltán Schay, L. Guczi, L. Borkó, Joe W. Hightower

Publikováno v: Applied Catalysis A: General. 124:L181-L187

Hydrogenation of 1,3-butadiene was investigated on catalysts prepared from an amorphous ribbon of composition Pd2Ni50Nb48, activated by oxygen and hydrogen treatments at 683 K. The hydrogenation activity of the sample decreased gradually with time, i
