Abstract
In reactors for heterogeneous synthesis, comprising a boiler and a heat exchanger inserted at least partially into the end catalytic beds, and at least an intermediate catalytic bed, two airspaces are now provided in each catalytic bed by introducing couples of annular walls, one of said airspaces being produced between the cartridge's internal wall and the perforated wall inserted close to it.
Claims5
A system to increase reactor yield of a reactor for heterogeneous synthesis which includes an internal boiler and an internal heat exchanger inserted at least partially into a catalytic layer comprising:
- a first catalytic layer, the first catalytic layer being partly connected to a boiler;
- a second catalytic layer, the second catalytic layer being party connected to a heat exchanger;
- at least one intermediate catalytic layer disposed between the first catalytic layer and the second catalytic layer;
- each catalytic layer having an internal annular wall and an external annular wall for defining a first airspace and a second airspace for each catalytic layer, the internal annular wall and external annular wall of each catalyst layer being at least partially perforated;
- the external annular wall of the first catalytic layer being perforated along an entire length thereof, the first airspace of the first catalytic layer being defined by the perforated external annular wall of the first catalytic layer and a cartridge wall of the reactor;
- the internal annular wall of the first catalytic layer being perforated along a length less than the length of the external annular wall of the first catalytic layer, the second airspace of the first catalytic layer being defined by the perforated internal annular wall of the first catalytic layer and a wall of the boiler;
- the external annular wall of the second catalytic layer being perforated along an entire length thereof, the first airspace of the second catalytic layer being defined by the perforated external annular wall of the second catalytic layer and the cartridge wall of the reactor;
- the internal annular wall of the second catalytic layer being perforated along a length less than the length of the external annular wall of the second catalytic layer, the second airspace of the second catalytic layer being defined by the perforated internal annular wall of the second catalyst layer and a wall of the heat exchanger.
