Methane Reforming with H<sub>2</sub>S and Sulfur for Hydrogen Production: Thermodynamic Assessment

نویسندگان

چکیده

Nowadays, most of the hydrogen is obtained from fossil fuels. At same time, effort and resources dedicated to development sustainable manufacturing processes are rapidly increasing promote energy transition toward renewable sources. In this direction, a potential source could be sulfide, produced as byproduct in several processes, particular oil extraction refinery operations. Methane reforming using H2S has recently attracted much interest for its economic environmental implications. Its conversion, fact, provides viable way elimination hazardous molecule, producing high-added value product like hydrogen. some still open key aspects process coke deposition due thermal pyrolysis methane endothermicity. work, with by co-feeding sulfur investigated through detailed thermodynamic analysis alleviate critical highlighted process. A parametric was conducted assess best conditions terms pressure, temperature, feed composition. Changing sulfur, H2S, composition can enhance system improving production yield, reducing carbon deposition, removal efficiency, necessary duty.

Thermodynamic analysis of methane reforming with CO2, CO2+H2O and CO2+O2 for hydrogen and synthesis gas production

Dry reforming of methane for the production of hydrogen and syngas has attracted much attention from both industrial and environmental aspects. The major problem encountered in the application of this process is the rapid deactivation of the catalyst, which is mainly due to coke accumulation and sintering of the catalyst. As an alternative to reduce the coke formation, the combination of CO2 re...

CO-Free Production of Hydrogen via StepwiseSteam Reforming of Methane

CO-free hydrogen is produced by the reversible cyclic stepwise steam reforming of methane for use in fuel cells and other processes that are sensitive to CO poisoning. The process consists of two steps involving the decomposition of methane in a first step followed by steam gasification of the surface carbon in a second step. The ease of carbon removal in step II is strongly dependent on temper...

Heat and Power Integration Opportunities in Methane Reforming based Hydrogen Production with PSA separation

Hydrogen is getting increasing attention by government and industry leaders, [1], as a very environmentally attractive and clean fuel because its oxidation leads only to water formation. There is abundance of hydrogen in nature, although it is only available for exploitation in a combined state, either in water, hydrocarbons, or coal [2]. Its recovery from these natural resources requires the a...

Comparison of several glycerol reforming methods for hydrogen and syngas production using thermodynamic analysis

This paper focuses on the comparison of different glycerol reforming technologies aimed to hydrogen and syngas production. The reactions of steam reforming, partial oxidation, autothermal reforming, dry reforming and supercritical water gasification were analyzed. For this, the Gibbs energy minimization approach was used in combination with the virial Equation of state. The validation of the mo...
