| titleOfInvention | Process for preparing unsaturated aldehyde and unsaturated carboxylic acid |
| abstract | The present invention utilizes a shell-and-tube type fixed bed reactor filled with a molded catalyst to form one or more starting compounds selected from propylene, isobutylene, t-butanol and methyl-t-butyl ether. , An improvement in the process for producing unsaturated aldehydes and unsaturated carboxylic acids by gas phase catalytic oxidation with oxygen molecules or oxygen-containing gases, which effectively suppresses the occurrence of hot spots or excessive heat generation at these hot spots and provides high yields. It relates to a process capable of producing unsaturated aldehydes and unsaturated carboxylic acids. The process is characterized in that a plurality of shaped catalysts having different activity levels are prepared by varying: [I] the content of inert components of the shaped catalyst and [II] (a) the occupied volume of the shaped catalyst, ( b) one or more elements of the type and / or amount of alkali metal (s) in the shaped catalyst, and (c) the calcination temperature of the shaped catalyst; Here the catalyst is charged to each reaction tube in such a way that the level of catalyst activity increases from the inlet side to the outlet side of each reaction tube. |
