Abstract
A reactor for performing endothermic catalytic reactions is disclosed formed of a monolithic counterflow reactor with parallel heating and reaction channels. The internal walls of the reaction channels are coated with a catalyst for the catalytic reaction to be performed, while the internal walls of the heating channels have a catalyst for the catalytic combustion of a fuel gas/air mixture.

A reactor for performing an endothermic catalytic reaction, comprising:
- an arrangement of a plurality of heating channels and a plurality of reaction channels running parallel to each other in a monolithic block, the heating channels and the reaction channels having walls containing a heat-resistant and gas-impermeable ceramic material, wherein:
- the reaction channels have internal walls coated with a catalyst for an endothermic catalytic reaction,
- the heating channels have internal walls coated with a catalyst for catalytic combustion, and
- the heating channels and the reaction channels are arranged in parallel strata which contain one or more layers of heating channels or reaction channels respectively in each strata.
A reactor for performing an endothermic catalytic reaction, comprising:
- an arrangement of a plurality of heating channels and a plurality of reaction channels running parallel to each other in a monolithic block, the heating channels and the reaction channels having walls containing a heat-resistant and gas-impermeable ceramic material, wherein:
- the reaction channels have internal walls coated with a catalyst for an endothermic catalytic reaction,
