The alkylation of toluene with methanol and the isomerization of xylene were investigated separately and in detail on zeolite H-ZSM-5 as catalyst. The influence of crystal size alone on rates and product distributions was studied for two Si/Al ratios

The kinetics of cracking of n -decane and n -hexane were investigated by observing the composition of the gas phase in contact with zeolite catalysts H-ZSM-5 and HY in a well-mixed closed system (gradientless batch-reactor). Catalyst temperature was

The concept of a rate-controlling process in compound kinetics is examined critically. A logically consistent foundation of the concept requires consideration of the dynamics of the entire system in different hypothetical states. Rate expressions for

The authors have shown recently that the isomer distribution in the xylene resulting from the methylation of toluene by methanol on zeolite H-ZSM-5 is independent of conversion as long as reactant methanol is not exhausted, and that it depends inter

Die Umwandlung von Rohstoffen in nutzliche Materialien und fertige Produkte und die Ruckfuhrung von Abfallen in Stoffkreislaufe sind Gegenstand des Chemieingenieurwesens. Stoff Umwandlung bedeutet oft auch die Durchfuhrung chemischer Reaktionen im te

The catalytic properties of pentasil-zeolites in the disproportionation of toluene at 640 – 730 K were investigated with respect to the influence of composition (Si : Al-ratio) and mode of synthesis (template) of the zeolite. The catalytic activity

The kinetics of sorption in most commercial adsorbents (e.g. charcoals or zeolites) results from the interaction of several distinct steps of mass transfer. In order to understand and analyse the compound kinetics it is expedient to design experiment
