MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202647101899 A) filed by Mitsubishi Chemical Corporation on August 24, 2026, for Catalyst Filling Method, Method For Producing (meth)acrylic Acid, And Reaction Tube.
Inventor includes Nitta Masanori.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Provided is a catalyst filling method with which it is possible to improve the yield of a target product in a reaction using a catalyst without performing a special catalyst manufacturing process. Provided is a method for filling a reaction tube 1 provided to a fixed-bed reactor with a catalyst 2, wherein the catalyst contains a solid catalyst and a fine powder catalyst, and the fine powder catalyst satisfies the relationships 0.010 mass% = X1 + X2 = 2.300 mass% and X1 X2 (X1 represents the amount (mass%) of the fine powder catalyst present in a reaction-gas-outlet-side region A1 with respect to 100 mass% of the total amount of the catalyst, and X2 represents the amount (mass%) of the fine powder catalyst present in a reaction-gas-inlet-side region A2 with respect to 100 mass% of the total amount of the catalyst, the reaction- gas-outlet-side region being a region in which 50 mass% of the total amount of 100 mass% of the solid catalyst is present by integrating from the reaction-gas-outlet 1B side, and the reaction-gas-inlet-side region being a region in which 50 mass% of the total amount of 100 mass% of the solid catalyst is present by integrating from the reaction-gas-inlet 1A side.
