Abstract
A reactor for synthesizing hydrogen sulfide in which sulfur and hydrogen are subjected to gas-phase reaction in the absence of a catalyst to synthesize hydrogen sulfide, the reactor including: a reactor body that retains liquid sulfur in a bottom portion thereof; a heating unit that gasifies part of the liquid sulfur; a hydrogen gas supply unit that supplies hydrogen gas into the liquid sulfur; and a heat-exchanging portion provided in a gas-phase reaction region located above the liquid surface of the liquid sulfur in the reactor body, wherein heat-exchanging portion is configured such that the reaction temperature in the gas-phase reaction region is controlled to be within a predetermined temperature range by changing the heat exchange amount per unit volume in a gas-phase reaction region located farther from the liquid surface from the heat exchange amount per unit volume in a gas-phase reaction region located closer to the liquid surface.
