An apparatus and method for producing hydrocarbons including aromatic hydrocarbons and/or lower olefins including propylene from CO H 2 while inhibiting reduction in catalyst activity and enhancing selectivity. The apparatus produces hydrocarbons including aromatic hydrocarbons having 6-10 carbon atoms and/or lower olefins including propylene, and is provided: a first supply unit which supplies a raw material gas containing CO and H 2 ; and a hydrocarbon production unit to which the raw material gas is supplied from the first supply unit, and which produces the hydrocarbons from CO and H 2 contained in the raw material gas while heating a catalyst structure at a temperature of 150° C. or more and less than 300° C. or at a temperature of 350° C. or more and less than 550° C., the catalyst structure includes supports having a porous structure and including a zeolite-type compound, and a metal fine particle present in the supports, the supports have channels communicating with outside the supports, and a portion of the channels have an average inner diameter of 0.95 nm or less. |
