A catalyst fibrous structure having a catalyst metal carried on a fibrous structure, wherein (a) a Log differential micropore volume distribution curve thereof obtained by measurement using a mercury intrusion technique has a peak having a maximum micropore diameter in the range of from 0.1 &#x3bc;m to 100 &#x3bc;m: (b) a Log, differential micropore volume at the peak is 0.5 mL/g or more; and (c) an amount of a catalyst metal compound and a binder carried per unit volume is 0.05 g/mL or more. Also, a production method for producing a catalyst fibrous structure.

Method for producing catalyst fibrous structure

Provided is an aldehyde production method that can provide target aldehydes with excellent aldehyde selectivity and a high conversion for a long period of time. The method includes bringing a mixed gas containing a vaporized primary alcohol and an inert gas into contact with a film-type dehydrogenation catalyst so as to dehydrogenate the primary alcohol in the mixed gas, thereby obtaining an aldehyde. The partial pressure of the primary alcohol in the mixed gas is 50 kPa or lower, and the film-type dehydrogenation catalyst is formed by providing a thin film catalyst layer on a support.
