The present disclosure relates to a fixed-bed gas-liquid hydrogenation reactor and a method for producing neopentyl glycol including the same, and more particularly, a plurality of holes through which a liquid raw material formed at the bottom passes and a plurality of gas raw materials passed through the bottom. A first distributor having cylindrical chimneys and cylindrical caps having a slot extending from the bottom while completely covering the chimney with a space therebetween; And a second distributor disposed below the first distribution plate at predetermined intervals and having a plurality of holes formed in the bottom thereof, wherein the height of the slot in the first distribution plate is the height of the chimney. 0.5 times or more, and the hole of the first dispersion plate is smaller than the hole of the second dispersion plate relates to a fixed bed gas-liquid hydrogenation reactor and a method for producing neopentyl glycol using the same. According to the present disclosure, through rapid mixing of the reaction raw materials and even dispersion into the catalyst layer, the catalyst utilization is increased without dead volume, so that the hydrogenation reaction yield is greatly improved, local side reactions are suppressed, and by-product formation is suppressed. In addition, there is an effect of providing a fixed-bed gas-liquid hydrogenation reactor and a process for preparing neopentyl glycol including the same, the reaction heat control being easy in a uniform reaction.
