Patent number: 6410786Abstract: A process for vapor phase catalytic oxidation of methacrolein to produce methacrylic acid at high yield and with stability over a prolonged period is provided. The process is characterized, in the occasion of producing methacrylic acid by vapor phase catalytic oxidation of methacrolein using a fixed bed shell-and-tube reactor, in that (1) the catalyst layer in each reaction tube is divided into at least two layers in the axial direction of the tube to provide plural reaction zones, and (2) each of the reaction zones is filled with the catalyst in such a manner that the amount of the catalytically active component per unit volume of the reaction tube decreases from the gas inlet portion toward the gas outlet portion.Type: GrantFiled: April 24, 2000Date of Patent: June 25, 2002Assignee: Nippon Shokubai Co, LtdInventors: Hideo Onodera, Naomasa Kimura, Eiichi Shiraishi
