The present invention addresses the problem of providing a bonded body which has a high airtightness and exhibits excellent durability under high-temperature and high-pressure conditions. This problem is solved by a bonded body in which a complex of a zeolite and an inorganic porous support, and a dense member are bonded together by an inorganic glass or an inorganic adhesive. The inorganic glass or the inorganic adhesive has a thermal expansion coefficient of 30×10/K to 90×10/K, and the inorganic glass has a softening point of 550° C. or lower. The present invention also addresses the problem of providing a method of efficiently producing an alcohol by installing a separation membrane in an alcohol synthesis reactor based on a bonding method that gives good sealing performance and durability under high-temperature and high-pressure conditions and in the presence of methanol vapor. This problem can be solved by an alcohol production method of obtaining an alcohol by allowing a raw material gas, which contains at least hydrogen and carbon monoxide and/or carbon dioxide, to react in the presence of a catalyst in a reactor. In the reactor for carrying out the reaction, an alcohol-selective permeable membrane bonded with a dense member is installed, and an alcohol generated by the reaction permeates and is recovered through the selective permeable membrane.

Bonded body, separation membrane module equipped with same, and method for producing alcohol

An alcohol production method in which an alcohol is produced from a carbonyl compound, the method including producing an alcohol by using a catalyst, the catalyst including a metal component including rhenium having an average valence of 4 or less and a carrier supporting the metal component, the carrier including zirconium oxide. A catalyst for producing an alcohol by hydrogenation of a carbonyl compound, the catalyst including a carrier including zirconium oxide and a metal component supported on the carrier, the metal component including rhenium having an average valence of 4 or less.

Method and catalyst for producing alcohol

A method for manufacturing a catalyst, which comprises regenerating a catalyst comprising a CHA zeolite as an active ingredient and having an ethylene conversion lowered through reaction of producing propylene by bringing into contact with ethylene in a vapor phase, by bringing the catalyst into contact with a gas which does not comprise oxygen and comprises hydrogen having a hydrogen partial pressure of 0.01 MPa or more as an absolute pressure thereof.
