HYDROGEN PRODUCTION BY CATALYTIC DECOMPOSITION METHANE OVER CARBON BLACK CATALYST IN A PILOT SCALE FLUIDIZED BED REACTOR
The thermos catalytic decomposition of methane is an environmentally attractive approach to CO2-free production of hydrogen. The fluidized bed was proposed for the continuous withdrawal of product carbon from the reactor. The usage of carbon black was reported as stable catalyst for decomposition of methane and the rubber grade carbon black was used as catalyst.
HYDROGEN PRODUCTION BY ANODIZED TIO2 NANOTUBE UNDER UV LIGHT IRRADIATION
Photocatalytic water splitting into H2 and O2 using semiconductors has received much attention, especially for its potential application to direct production of H2 for clean energy from water utilizing solar light energy. Since the report of Fujishima and Honda on the water splitting by photo electrochemical cells, numerous different semiconducting materials have been used as photo catalysts for hydrogen generation from water. Among them, platinized titania significantly accelerates for hydrogen generation from water. For geometrical improvement of TiO2 particle, porous TiO2 structure was proposed and studied such as nanofiber, nanorod and nanotubes.
