摘要:
Disclosed is a reactor-exchanger or an exchanger comprising at least 3 levels, each of which includes at least one region with millimeter channels promoting heat exchange and at least one distribution region upstream and/or downstream of the region with millimeter channels, characterized in that the reactor-exchanger or exchanger is a unit that has no mounting interfaces between the various levels.
摘要:
The invention relates to a catalytic reactor including at least two catalytic cellular architectures and at least one structural element, inserted between the two catalytic cellular architectures, in which the entire outer perimeter is in contact with the inner wall of the reactor, the cellular architecture and the structural element being arranged coaxially.

The invention relates to a method for producing a packing structure, characterised in that it includes the following main steps: a) a step comprising the hydrothermal synthesis of the packing mass, performed using a mixture of quicklime and silica; and b) a step comprising the drying of the packing mass produced in step (a) at a temperature T2 of between 110°C and 500°C, possibly with at least one intermediate stage performed at a temperature of between 111°C and 350°C over a period t2 selected such that the physisorbed water content of the packing mass is less than 0.5%.
