Reactor and method for equilibrium-limited reactions

1. A reactor for implementation of equilibrium-limited reactions, the reactor comprising:

a reaction space;

a reactant feed;

an outlet for reaction products;

a device for accommodating catalyst material; and

a stirrer device comprising:

a hollow shaft with a gas inlet opening at one end of the hollow shaft;

a first stirrer paddle with gas exit orifices mounted on the hollow shaft; and

a second stirrer paddle mounted on the hollow shaft proximate the device for accommodating the catalyst material.

2. The reactor as claimed in claim 1 , further comprising:

a liquid phase zone in a lower region of the reaction space; and

a gas phase zone above the liquid phase zone;

wherein the first stirrer paddle is disposed in the liquid phase zone and the second stirrer paddle is disposed in the gas phase zone.

3. The reactor as claimed in claim 2 , further comprising a liquid sorbent disposed in the liquid phase zone.

4. The reactor as claimed in claim 1 , wherein the second stirrer paddle comprises a radially conveying stirrer.

5. The reactor as claimed in claim 1 , wherein the first stirrer paddle extends radially with respect to the hollow shaft between 20% and 30% of a diameter of the reactor space.

6. The reactor as claimed in claim 1 , wherein an effective velocity of the first stirrer paddle is between 5 m/s and 15 m/s.

7. A method of implementing equilibrium-limited reactions, the method comprising:

introducing a catalyst material into a reactor;

introducing reactants into the reactor;

stirring the reactants with a stirrer comprising a hollow shaft;

reacting the reactants resulting in a product; and

transporting a gas mixture from an upper region of the reactor through the hollow shaft into a lower region of the reactor;

wherein the stirrer sucks in the gas mixture and discharges the gas mixture from gas exit orifices in a first stirrer paddle mounted on the hollow shaft into the catalyst mixture; and

a second stirrer paddle mounted on the hollow shaft disperses the gas mixture throughout the catalyst material.

8. The method as claimed in claim 7 , further comprising supplying a liquid sorbent to the reactor;

wherein the liquid sorbent accumulates in a liquid phase zone in the lower region; and

discharging the gas mixture into the liquid phase zone with the first stirrer paddle.

9. The method as claimed in claim 8 , further comprising distributing the gas mixture in a radial direction with the second stirrer paddle in a gas phase zone above the liquid phase zone.
