Abstract
Novel zeolite-containing particles. The particles are free-flowing, discrete, rounded, rigid, frangible, hollow, and opaque. The shell or wall of each particle is porous to gases and fluids. The particles are useful as catalysts for refining processes. They are essentially completely de-coked upon regeneration, and they retain their catalytic activity even after several cycles of use-regeneration.
