clean hydrogen is the major energy carrier for power production. the conversion of co to co2 and zero emission during hydrogen energy production causes high capital cost. it is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. in this era, coal gasification is the most promising technology for t...

In this study, the effect of the levels of hydrogen addition to methane-air premixed flame in a micro-stepped reactor has been studied numerically. In addition, the effects of mixture velocity and walls’ thermal conductivity (Kw) on the flame’s location, temperature, and species distribution in a micro reactor were calculated using a 2D numerical laminar steady code. The results ...

The hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of H+ to NaBH4. The sulfonated porous carbon (SPC) is used as a source of hydrogen ion and catalyst. It is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of NaBH4 to generate hydrogen gas at room temperature in comparison to Amberlyst-15 and Nafion-NR50. The ki...

To solve problems related to global warming, environmental pollution, and green energy fields, a lot of research is now devoted the catalysis biofuels biogas transformation into syngas hydrogen [...]

millions of dollars are being spent worldwide on the repair and maintenance of sewer networks and wastewater treatment plants every year. the production and emission of hydrogen sulfide has been identified as a major cause of corrosion and odor problems in sewer networks. prediction of hydrogen sulfide production in the sewer system helps the engineers and manager to obtain a proper strategy fo...

The growing environmental concerns associated with global warming along the exponential rise in energy demand are boosting production of clean energy. combined process biomass pyrolysis and in-line catalytic steam reforming is a promising alternative for selective hydrogen from renewable sources. This Primer provides general overview fundamental aspects that influence potential process. Recent ...
