Abstract
A porous ceramic composition suitable for use as a catalyst support for demetalation of asphaltene-containing feedstocks is made from the tubular form of the clay halloysite by dispersing the rods of the clay.
Claims4
A porous composition of matter comprising:
- dispersed rods of halloysite, and 0-15 percent by weight of a binder oxide, based on the total weight of said halloysite and binder oxide having a pore volume of at least 0.35 cc/gm of which at least 70 percent of the pore volume is present as pores having a diameter of between 200-700 Angstroms and at least 70 percent of said pores have a diameter of 300-700 Angstroms.
