Production of Maleic or Fumaric Acid from Levulinic Acid

Anargyros Chatzidimitriou (Inventor), Jesse Bond (Inventor)

Research output: Patent

Abstract

The production of maleic acid and fumaric acid (or the anhydride form of either, maleic anhydride) via gas-phase, oxidative cleavage of levulinic acid in a single packed bed reactor over a reducible oxide catalyst. The production may be carried out in an initial mixing vessel into which levulinic acid is continuously charged and mixed with both inert (He, N2, Ar, etc.) and oxidizing (O2, air, etc.) gases. The feed stream can then be safely heated to reaction temperature, which generally ranges from 200-500° C., without initiating polymerization, in a second stage preheater that thermally equilibrates the gaseous mixture of LA, O2, and inert diluent and fed to a third stage catalytic reactor for final processing.
