A natural erionite ore has been exchanged with ammonium and nickel salts to yield a Ni/H erionite catalyst that is active and stable for selectively hydrocracking only the n-paraffins from light straight-run naphthas. The primary product is a C[sup 5

A sulfided Ni/H-erionite catalyst was prepared from the natural mineral, and its catalytic characteristics for hydrocracking n-alkanes were studied. Because of its shape selectivity toward straight chain hydrocarbons, branched products were largely a

Previous studies reported that synthetic TMA-offretite is an open large-pore (12-membered oxygen ring opening) zeolite. Closer reexamination of the odd l lines using high intensity X-ray diffraction and additional catalytic diagnostic studies suggest

Thermal hydrogasification of heavy petroleum oils was investigated under conditions of short reaction time (0.5-15 s products residence time) and varied heating rates to elevated temperatures (50-850 /sup 0/C/s to > 550 /sup 0/C). Total pressures and

Methanol, in the presence of toluene, was completely converted to hydrocarbons above 400 °C. However, depending on the ratio of toluene to methanol in the feed mixture and the reaction severity, only a fraction of the methanol participated in the to

Under high hydrogen pressure, zeolites X and Y exchanged with Ce, La, or mixed rareearth ions showed sustained catalytic activity in cracking n -hexadecane. The carbon number distribution of the cracked product agrees well with that obtained with hyd
