Acidity and catalytic activity of zeolite catalysts bound with silica and alumina
(Texas A&M University, 2004-09-30)Zeolites ZSM-5 (SiO2/Al2O3=30~280) and Y(SiO2/Al2O3=5.2~80) are bound with silica gel (Ludox HS-40 and Ludox AS-40) and alumina (γ- Al2O3 and boehmite) by different binding methods, namely, gel-mixing, powder-mixing and ... -
Applications of hydrogenation and dehydrogenation on noble metal catalysts
(2009-05-15)Hydrogenation and dehydrogenation on Pd- and Pt- catalysts are encountered in many industrial hydrocarbon processes. The present work considers the development of catalysts and their kinetic modeling along a general and ... -
Catalysts for the hydrolysis of thiophosphate triesters
(Texas A&M University, 2005-02-17)The degradation of phosphate triesters is efficiently catalyzed by organophosphate hydrolases (OPH). While a number of recent studies have focused on optimizing the rate of hydrolysis observed with the native enzyme, no ... -
