hydrogen as an ideal energy carrier can play a very important role in future energy systems for hydro-gen production can be used a variety of technologies and sources. one of the most promising methods for large-scale hydrogen production is thermo-chemical water decomposition using heat energy from nuclear, solar and other sources. the water splitting thermo-chemicals cycles are processes where...

Hydrogen is a valuable gas as a clean energy source and as feedstock for some industries. Therefore, demand on hydrogen production has increased considerably in recent years. Electrolysis of water, steam reforming of hydrocarbons and auto-thermal processes are well-known methods for hydrogen gas production, but not cost-effective due to high energy requirements. Biological production of hydroge...

BACKGROUND Second generation hydrogen fermentation technologies using organic agricultural and forestry wastes are emerging. The efficient microbial fermentation of hexoses and pentoses resulting from the pretreatment of lingocellulosic materials is essential for the success of these processes. RESULTS Conversion of arabinose and glucose to hydrogen, by extreme thermophilic, anaerobic, mixed ...

an eight week study was conducted to investigate the effect of inclusion of tomato waste meal in layer diets on laying performance, egg quality and lipid profile as a means to reduce feed cost and pollution. four laying diets containing tomato waste meal (twm) at four levels of 0, 3, 6 or 9% were assigned randomly to 4 groups of 40 birds divided among four replicates of 10 birds in each dietary...

A new thiosemicarbzone compound was prepared by the reaction of acenaphthenequinone and thiosemicarbazide (1:1 molar ratio) in absolute methanol at 70°C. The crystal structure of this compound, acenaphthenequinone thiosemicarbazone mono methanol, was determined by X-ray crystallography. The unit cell parameters are as follows: a = 7.0384(14) Ǻ, b = 14.202(3) Ǻ, c = 14.270(3) Ǻ, β = 104.26(3)°. ...

Rhodopseudomonas acidophila KU001 was isolated from leather industry effluents and the effect of different cultural conditions on hydrogen production was studied. Anaerobic light induced more hydrogen production than anaerobic dark conditions. Growing cells produced more amounts of hydrogen between 96 and 144 h of incubation. Resting and growing cells preferred a pH of 6.0 ± 0.24 for hydrogen p...

Hydrogen has been known as a clean and suitable fuel to replace conventional fossil fuels. One of the common hydrogen production methods is using water electrolysis process. This method produces oxygen as well as hydrogen by ratio of 1:2. The aim of this work is to investigate the effects of inlet air enrichment by adding produced hydrogen and oxygen to an internal combustion engine. For this p...
