An experimental device for catalytic decomposition of water over zeolites with possibilities of measuring the mass variation of zeolites during UV radiation was built.

Hydrogen was produced in a quartz reactor from the overheated steam of water using zeolites activated at 500°C under a vacuum of 10−2 mmHg.

Fossil fuels use has caused serious environmental impacts worldwide, mainly related with the greenhouse effect intensification. One strategy to mitigate such impacts is the use of hydrogen in combustion processes. Additionally, hydrogen can be utilized as an energy vector for storage purposes...

Formulating passive energy design strategies require an understanding of the climatic influence on buildings and the thermal comfort of their occupants. This paper presents the bioclimatic approach in building design as well as the techniques which are applied to formulate various strategies in...
