Adsorption behavior of NO and CO as well as their reaction was investigated on cobalt supported zeolite beta (Co/BEA) prepared by solid-state ion exchange (S SIE) and by impregnation (IMP). By temperature programmed desorption (TPD), two NO desorptio

Isomerization of n -hexane over Pt containing sulfated zirconia (Pt/SZ) and SZ was followed by in situ IR measurements. A constant conversion and high selectivity to iso-hexanes were only observed with Pt under hydrogen as carrier gas. In the IR spec

On a fresh BEA zeolite, skeletal isomerization of 1-pentene is accompanied by various side reactions, such as dimerization–cracking, hydrogen transfer and coking. Coking causes a significant increase in skeletal isomerization and a decrease in the

The skeletal isomerization of 1-pentene at 1.2 bar total pressure and 30 mbar 1-pentene partial pressure was investigated by in situ IR measurements over FER and BEA zeolites. If the reaction was carried out isothermally a small loss of Bronsted acid

Differently prepared Ni and Pt containing HMFI, HMOR and HBEA zeolites for the hydroconversion of n-nonane were studied. The objective was to investigate the role of acid and metal site density, the influence of the kind of the metal, and the pore di

Nickel containing HMFI, HMOR and HBEA zeolites was prepared by impregnation and liquid- and solid-state ion exchange. The kinetics of the solid-state ion exchange of the protons (Bronsted acid sites) with NiCl 2 was followed by IR and TPE measurement
