The Sintering of Supported Metal Catalysts
Sieghard E. Wanke,Peter C. Flynn +1 more
TL;DR: In this article, the use of these supported metal catalysts increases the utilization of the metal as a catalyst since a large fraction of the surface metal atoms are at the surface of the small metal crystallites.
Journal ArticleDOI
A model of supported metal catalyst sintering: I. Development of model
Peter C. Flynn,Sieghard E. Wanke +1 more
TL;DR: In this article, an interparticle transport model for the sintering of supported metal catalysts is developed, which postulates escape of atoms from crystallites to the support surface, rapid migration of these atoms along the surface, and their recapture by crystallites upon collision.
Journal ArticleDOI
The sintering of supported metal catalysts: II. Comparison of sintering rates of supported Pt, Ir, and Rh catalysts in hydrogen and oxygen
TL;DR: In this paper, changes in dispersion of alumina supported Pt, Ir, and Rh catalysts due to thermal treatment (250-800 °C) in oxygen and hydrogen atmospheres were measured.
Journal ArticleDOI
The sintering of supported metal catalysts: I. Redispersion of supported platinum in oxygen
R. Fiedorow,Sieghard E. Wanke +1 more
TL;DR: In this article, the effects of treatment in oxygen at elevated temperatures on the dispersion of five Pt/MAl2O3 catalysts (0.5 to 4.0 wt% Pt) were determined.
Journal ArticleDOI
Effect of molecular structure distribution on melting and crystallization behavior of 1-butene/ethylene copolymers
TL;DR: In this article, the melting and crystallization measurements on PTthis article fractions of the two polymers showed that the melting temperature, crystallization temperature and enthalpy of fusion of the PTthis article fraction for the Ziegler-Natta polymer decreased substantially with increasing SCB content.
