PROBLEM TO BE SOLVED: To provide a catalytic reaction device which actuates in a wide temperature range including a low temperature (for example below the freezing point), which includes a warm-up function allowing stable reproduction at a temperature lower than the conventional temperature (for example around 160°C) and which exhibits high catalytic activity irrespective of a use temperature environment.SOLUTION: A catalytic reaction device includes: a warm-up means (40) including a chemical thermal storage material which radiates heat when ammonia is immobilized and stores heat when ammonia is desorbed; and a catalyst reaction part (20) including a catalyst layer A (10A) including a purifying catalyst which purifies gas and performing heat exchange with the warm-up means, and a catalyst layer B (10B) including the purifying catalyst which purifies gas and arranged on the side which does not oppose to the warm-up means of the catalyst layer A. |
