摘要: 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.

摘要: Process for refining hydrocarbon feedstocks comprising contacting a hydrocarbon feedstock with zeolite-containing particles that are free-flowing, discrete, rounded, rigid, frangible, hollow, and opaque. The zeolite-containing particles are essentially completely de-coked upon regeneration, and then retain their catalytic activity even after several cycles of use-regeneration.
