Latest Patents
Sumida's latest patents revolve around processes for producing metal oxide catalysts. The first patent describes a method for producing a metal oxide catalyst suitable for the production of acrylic acid or acrylonitrile through a catalytic oxidation reaction of propane. This innovative process utilizes fine particles of metallic tellurium, which are obtained by reducing a tellurium compound with a reductant. The resulting catalyst, which includes metal elements such as Mo, V, Nb, and Te, allows for a higher yield of acrylic acid, achieving not less than 40%.
The second patent also focuses on a process for producing metal oxide catalysts capable of generating acrylic acid or acrylonitrile in a single stage. This invention employs finely ground metallic tellurium or antimony in water or an organic solvent as raw materials. The catalyst produced from this method can yield acrylic acid in a high yield of 35% or more from propane.
