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.

Method for producing aldehyde

The invention is a column contact apparatus for contacting gas with liquid in an upflow in a column container, containing two or more stages of honeycomb structural bodies in the column container in a vertical direction, a space portion formed between the respective stages of the honeycomb structural bodies and a flow-aligning portion as back-flow prevention means provided in the space portion between the respective stages such that the flow-aligning portion is not brought into contact with the honeycomb structural bodies, the flow-aligning portion including a plurality of holes with hole diameters of 0.5 mm to 8 mm.

Column contact apparatus and method for operating the same

The present invention provides a method for manufacturing a film catalyst, including forming a catalyst layer on one side or each side of a base material to obtain a film catalyst, bending the film catalyst, and optionally cutting the film catalyst, wherein the bending step is conducted by bending the film catalyst with a bending tool composed of two gears that are oppositely arranged as meshing each other while a protective material having a compressibility of 40 to 95% is inserted between the catalyst layer of the film catalyst and the two gears.

The invention provides a method of using an alcohol and a primary or secondary amine as the starting material to produce the corresponding secondary amine easily at a high yield and a catalyst used therein. The invention relates to a film-type catalyst for production of a tertiary amine, which is used in producing a tertiary amine from an alcohol and a primary or secondary amine as the starting material, and a process for producing a tertiary amine, which includes reacting an alcohol with a primary or secondary amine in the presence of the film-type catalyst.

Process for producing tertiary amine

A molded sheet containing at least an oxidizable metal, a moisture retaining agent, and a fibrous material and having a content of components other than the fibrous material of 50% by weight or higher. The sheet has a thickness of 0.08 to 1.2 mm and a breaking length of 100 to 4000 m.

Molded sheet

A process of producing a heat generating molded article comprising the steps of making an intermediate product by a papermaking process from a raw material composition containing at least an oxidizable metal powder, a moisture retaining agent, a fibrous material, and water and incorporating an electrolyte into the resulting intermediate product.

Method for producing heat-generating formed product

A pulp molded container comprising a pulp molded article () having on the inner surface and/or the outer surface thereof a resin layer () with a thickness of 5 to 300 &#x3bc;m formed by applying a coating, wherein the thickness ratio of the resin layer () to the molded article () (former/latter) is 1/2 to 1/100, and the surface roughness profile of the outer or inner surface of the pulp molded article is such that a centerline average roughness (Ra) is 0.5 to 20 &#x3bc;m.
