<p>In a process for disproportionation of an olefinic feedstock, such as FCC gasoline, the feedstock is contacted with a catalyst comprising an inorganic, porous, non-layered crystalline phase material having, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than about 18 Angstrom units with a relative intensity of 100 and having a benzene adsorption capacity greater than 15 grams of benzene per 100 grams of said material at 6.7 kPa (50 torr) and 25 °C.</p> |
