A method for producing an alcohol having 8 or more and 22 or less carbon atoms includes the following steps: step 1: forming a porous layer on a surface of a porous material having a pore size mode of 30 nm or more and 200 nm or less to obtain a bimodal carrier; step 2: supporting cobalt on the bimodal carrier obtained in step 1 to obtain a catalyst having peaks of pore distribution in a range of 1 nm or more and 25 nm or less and a range of 30 nm or more and 200 nm or less, respectively; and step 3: reacting carbon monoxide with hydrogen at a gauge pressure of 2 MPa or more and 100 MPa or less in the presence of the catalyst obtained in step 2.

Method for producing alcohol

The present invention discloses a method for producing an olefin through decarbonylation of a carboxylic acid having a &#x3b2;-hydrogen atom or a derivative thereof in the presence of a catalyst containing at least one metal element selected from Groups 9, 10, and 11 metals under conditions with a concentration of carbon monoxide of not less than 41 mmol/L.

Method for producing olefin

The present invention provides a method for producing an olefin from a carboxylic acid having a &#x3b2;-hydrogen atom or an anhydride thereof in the presene of a catalyst containing at least one metal element selected from metals of Group 8, Group 9 and Group 10 and bromine element at a reaction temperature of 120&#xb0; C. to 270&#xb0; C.
