Latest Patents

Okada is associated with 1 patent, titled “Method for Producing a Catalyst for Unsaturated Carboxylic Acid Synthesis.” The invention describes preparing a catalyst by drying and heat-treating a mixed liquid containing source compounds for the catalyst’s component elements. The resulting dried material, or powder derived from it, is supported on a carrier as a particle aggregate to form a catalyst precursor, which is then calcined.

The method specifies limits for the powder’s mass loss: less than 5 percent at 300°C, and a difference of 1 to 6 percent between its mass loss at 370°C and at 300°C. These conditions define key parameters in the catalyst-production process.
