This heat exchanger (100) includes a core portion (1), a header portion (2), and an intermediate member (3), and the curvature radius of a corner (31a to 31d) of the intermediate member is configured to be smaller than the curvature radius at a header portion side.

Certain configurations described herein comprise a reformer that is operative to liberate hydrogen gas from a hydrogen-rich feedstock in a catalytic reforming reaction, where a hydrogen purifier is effective to remove and purify hydrogen gas, in a thermally integrated assembly combining the reformer and purifier. Methods of using the combined reformer/purifier are also described.

The invention relates to a device, stacked plate reactor and to a method for investigating chemical processes to be carried out simultaneously or almost at the same time on a large number of functional element variations of the process parameters.
