| Abstract |
This invention provides a reactor for exothermic heterogeneous synthesis reaction for producing compounds such as ammonia, in which the synthesis gas is reacted in several catalytic beds with axial-radial of just radial flow, the reacted gas is collected at the outlet from the last catalytic bed and is transferred to a reaction heat recovery system situated at the top of the reactor. The reactor comprises three catalytic beds with at least two inverted curve bottoms, a first quenching system with its distributor situated inside the first upper bed, immediately under the imperforated portion of the internal wall of said bed, a gas/gas exchange central to at least one of the two upper beds, a water bottleneck, and an internal central tube to take to the top the reacted gas collected in the third bed. |
