Low Speed Collision Avoidance Systemnt Si/Al ratios. The reactions were done in the vapor phase, using a fixed bed continuous flow reactor at different temperatures and for different contact times..With acetic acid only pentasil zeolites with intermediate acid strength were inducing zeolite-dependent selectivities, giving in this way

Jürgen Valldorf,Wolfgang Gessner On each of the zeolites, the coke was characterized by conventional analysis (GC, HPLC, NMR, MS) of the solvent extracts obtained after dissolution of the zeolite framework by hydrofluoric acid. Coking, aging rates and coke composition are definitely dependent on the zeolite porous structure, which

In two examples (the constraint index and the selectivity of m-xylene transformation) we show that numerous other factors can influence these select
