Addressing recent environmental regulations on fossil fuel power systems and both biomass fuel supply and coal greenhouse gas issues, biomass/coal co-gasification could provide a feasible transition solution for power plants. In the quest for an even more sustainable process, steam...

Integrated Gasification Combined Cycle (IGCC) represents a commercially proven technology available for the combined production of hydrogen and electricity power from coal and heavy residue oils. When associated with CO2 capture and sequestration facilities, the IGCC plant gives an answer to the...

The production of hydrogen combined with carbon capture represents a possible option for reducing CO2 emissions in atmosphere and anthropogenic greenhouse effect. Nowadays the worldwide hydrogen production is based mainly on natural gas reforming, but the attention of the scientific community is...

With the rapid development of industry, more and more waste gases are emitted into the atmosphere. In terms of total air emissions, CO2 is emitted in the greatest amount, accounting for 99wt% of the total air emissions, therefore contributing to global warming, the so-called “Greenhouse...

This study investigates configuration of a module for withstanding high pressure and temperature for CO2 capture from a coal gasifier. In order to increase the durability of the module at high pressure and temperature, a flange-type unit-cell module was installed in a high-pressure chamber....

Coal use for electricity generation will continue growing in importance. In the present work the optimization of a high efficiency and zero emissions coal-fired plant, which produces both hydrogen and electricity, has been developed. The majority of this paper concerns an integration of...

The thermodynamics of a solar thermochemical cycle for the capture of CO2 from air are analyzed. The cycle encompasses 3 reactors: an aerosol-type carbonator for capturing CO2 from air using a spray of Ca(OH)2 aqueous solution, a solar calciner for thermally decomposing CaCO3 into CaO using...

Hydrogen, a promising and clean energy carrier, could potentially replace the use of fossil fuels in the transportation sector. Currently, no environmentally attractive, large-scale, low-cost and high-efficiency hydrogen production process is available for commercialization. Solar-driven...

The most thermodynamically favorable operating conditions at which glycerol can be converted into hydrogen with maximum hydrogen yield by autothermal reforming using supercritical water were identified in a previous paper. As a second part of the study, a conceptual design based on energy...
