    摘要: The present invention relates to a process for the formation of acetone from acetic acid. The process is conducted at an elevated temperature of above 225° C. by contacting a feed stream containing acetic acid, and an optional carrier gas, with a catalyst. The catalyst comprises a support that is favorable for the production of acetone. The support may comprise titania, zirconia, ceria, silica, iron oxide, and carbon, but preferably is titania, zirconia, and ceria.
