HYDROGEN GENERATOR USING SOLAR ENERGY FOR DISSOCIATION OF WATER

摘要

Hydrogen is produced by dissociation of water in a rotary tubular reactor (1) having a receiving end capped with a cap (2) transparent to solar radiation and provided with a small window (12) connecting a collecting chamber ( 3) has an insulated opaque heating chamber (5). The tubular reactor (1) constitutes a "dark room" furnished with two series of tubes (7, 8) for heating and dissociation of water. Tubes (7) have a porous section (7a) for the separation of hydrogen by molecular diffusion from Knudsen. The concentrated solar radiation entering through the small window (12) falls on one end of the tubes (7, 8) and is absorbed for the most part by multiple reflections on these tubes. Slow rotation of the reactor (1) compensates for the bending effects due to gravity.
