Heteronormativität in der Zoologieisation of 1,3-butadiene and styrene. Great industrial importance has the production of polyethylene and polypropylene by Phillipps-and Ziegler-Natta catalysis. Beside these classical catalysts, catalysts such as metallocenes, half-sandwich, nickel, palladium, and iron complexes have been synthesize

Jutta Hartmann,Christian Klesseted. There are three fundamental reasons for catalyst deactivation, i.e. poisoning, coking or fouling and ageing. Poisoning can be reversible or irreversible, and with geometric or electronic effect. It can also be selective, nonselective and antiselective, depending on catalyst/poison affinity and

Bettina Fritzsche,Jutta Hartmannn and applied one. . belong to the class of unsteady state reaction processes, specifically to the class of forced periodic processes (see for example ). They are an extreme form of modulation of initial concentrations and can only be used in heterogeneous catalysis. A description of the princi

This value is roughly two orders of magnitude higher compared to conventional production vessels..Due to the small reactor dimensions diffusion times are short and

Alexander A. Ignatiev,Alexander V. Lyashenkoy in catalytic reforming have been intensively studied for many years. Due to environmental concerns the aromatic content of gasoline will have to be reduced. In addition, the possible introduction of hydrogen as an alternative motor vehicle fuel may seriously threaten the role of catalytic reformin
