Leidy Peña
Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...

Thermochemical Hydrogen Production by Alkali Metal Oxides

Oct 16, 2011
Hiroki Miyaoka
In this work, we have focused a thermo chemical hydrogen production from water by using alkali metal oxides. This system consists of three step reactions. First one is H 2 generation by the reaction of hydroxide and metal 2MOH+2M→2M 2 O+H 2 (endothermic). From the oxide as the product of first...

Fouling Monitoring Techniques for Water Treatment Membrane Processes
