This invention discloses a reactor for water-gas shift reaction and its application. The reactor is suitable for water-gas shift reaction processes containing gaseous and liquid reactants. A
reaction chamber is set inside a hollow, sealed cylinder formed by the reactor walls. The
reaction chamber is a hollow, sealed chamber surrounded by porous material as its wall surface. A gaseous reactant inlet
pipe penetrates the reactor wall and extends into the upper part of the
reaction chamber, a liquid reactant inlet
pipe penetrates the reactor wall and extends into the cylinder, and a
reaction product outlet
pipe penetrates the reactor wall and extends into the lower part of the reaction chamber. The catalyst for the water-gas shift reaction is packed in the reaction chamber. The water-gas shift reaction can be carried out under near-isothermal conditions. Water in the liquid reactant does not need to be pre-vaporized and is directly fed into the reactor in liquid form, saving the
energy consumption required to transport the corresponding amount of
water vapor. Simultaneously, a high
molar ratio of water to
carbon monoxide is maintained within the reactor, promoting complete conversion of
carbon monoxide.
