Catalyst manufacturing method and acrylic acid manufacturing method |
| abstract |
The method for producing a catalyst provided by the present invention is a catalyst used in the gas-phase catalytic oxidation reaction for the production of unsaturated carboxylic acids such as acrylic acid and methacrylic acid from unsaturated aldehydes such as acrolein and methacrolein. It is a catalyst with high raw material conversion rate and product selectivity, and excellent unsaturated carboxylic acid yield. The method for producing a catalyst of the present invention includes a method for producing an unsaturated carboxylic acid synthesis catalyst including a step of forming a powder containing each catalyst component element to form a catalyst precursor; In this forming step, a sulfur-containing inorganic compound is added and the powder is formed. |
