Title:
CATALYST MOLDED ARTICLE, CATALYST MOLDED ARTICLE FOR PRODUCING METHACROLEIN AND/OR METHACRYLIC ACID, AND METHOD FOR PRODUCING METHACROLEIN AND/OR METHACRYLIC ACID
Document Type and Number:
WIPO Patent Application WO/2020/196853
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a catalyst with which it is possible to produce methacrolein and/or methacrylic acid stably over an extended period of time while maintaining high reactivity in raw-material compounds and high selectivity, and a method for producing methacrolein and/or methacrylic acid. A catalyst molded article that satisfies formula (1) and formula (2), where X is the density (g/cm3) of the catalyst molded article, Y is the filled bulk density (g/cm3) of the catalyst molded article, and Z is the representative length (cm) of the catalyst molded article. Formula (1): 0.700 (g/cm3)2 ≤ (X × Y) ≤ 1.200 (g/cm3)2
Formula (2): 0.050 g/cm2 ≤ (X × Z) ≤ 0.130 g/cm2
