COMPOUND CATALYST COMPOSITION

摘要

A compound catalyst composition, useful for many chemical processes, comprises a compounding refractory oxide and a precursor catalyst composition with one or more functional surface active constituents integrated on and/or in the substrate surface. The precursor catalyst composition comprises a substantially nonmicroporous/nonmesoporous substrate having macropores having a total surface area between about 0.1 m²/g and 50 m²/g; and preferably, a predetermined isoelectric point (IEP) obtained in a pH range greater than 0, preferably greater than 6.0, but less than or equal to 14. At least one catalytically-active region may be contiguous or discontiguous and has a mean thickness = about 30 nm. Preferably, the precursor catalyst composition is a functional surface catalyst composition comprising a glass having a SARC_Na = about 0.5. The compounding refractory oxide and the precursor catalyst composition are intermixed after the precursor catalyst composition is produced.
