Hydrogen gas has been successfully produced from sewage sludge by supercritical water gasification. Therefore, whether …

from various lignocellulosic biomasses was investigated by strain AK54, a saccharolytic, thermophilic ethanol and hydrogen … ethanol, acetate, lactate, hydrogen and carbon dioxide. By lowering the partial pressure of hydrogen during glucose … degradation, the end product formation was directed towards hydrogen, acetate and ethanol but away from lactate. Hydrogen and …

We researched the structural effect of titania photocatalysts on the yield of hydrogen gas from water splitting. We … (XRD), scanning electron microscopy (SEM), and UV–Vis spectra. After analysis of photocurrent and hydrogen generation, we … concluded that with different structures, MTTFs generate photocurrents and hydrogen with different efficiencies. The results …

A new method for the methanation of hydrogen and carbon dioxide is presented. In a novel anaerobic trickle-bed reactor … hydrogen electrolysis (or other methods of hydrogen production). The combination with conventional biogas plants under hydrogen …

Using wavelet-based multiresolution analysis, this study investigates the effect of hydrogen addition on cyclic … air ratio of 1.4 is used. Three cases are examined: natural gas with no hydrogen added, and natural gas with the addition … of 23% and 40% hydrogen by volume. The time series of the indicated mean effective pressure are analyzed over 192 engine …

diesel engine with naturally aspirated hydrogen at the engine speed of 1800revmin−1 under five engine loads. Hydrogen was … to high loads. At 90% load, abnormal combustion occurs with more than 30% hydrogen addition as indicated by the drastic … emissions (except for formaldehyde) can be efficiently reduced. More than 30% of hydrogen addition can reduce the HC emission at …

Fermentative hydrogen production from biomass wastes is a promising technology combining waste treatment and clean fuel … from heat pre-treated anaerobic digestion sludge, to directly examine the substrate consumption and hydrogen production … during the co-fermentation of monosaccharides and amino acids. Hydrogen was mainly produced from the fermentation of …

was evaluated in anaerobic single-batch reactors at 37 °C for 70 h. Hydrogen production from cassava, dairy and citrus WW … year−1, the highest in this study. Cassava WW showed the highest hydrogen production potential (97.9 mL), when compared with … hydrogen and methane process could increase energy recoveries and economic yields to values near 10.48 kJ g−1 COD and US$ 0 …
