H2 enrichment from synthesis gas by Desulfotomaculumcarboxydivorans for potential applications in synthesis gas purification and biodesulfurization

Biodesulfurization of Flue Gases Using Synthesis Gas Delivered as Microbubbles

Introduction Anaerobic treatment processes for biodegradation of hazardous materials have increasingly been gaining attention in environmental applications. Microbial processes utilizing sulfate reducing bacteria (SRB), in particular, have found potential applications in variety of treatment processes such as flue gas desulfurization [1,2], gypsum reclamation [3], sulfur recovery from sulfitdsu...

Investigation of CO2 and H2O Addition to Natural Gas for Production of Synthesis Gas

General modeling and optimization of syngas production via noncatalytic autothermal partial oxidation of methane are carried out using our developed scientific software which was based on the minimization of total Gibbs energy. In this work, a novel application of the direct search and Newton-Raphson methods was introduced to apply to optimization of a complex chemical reaction. Sensitivity ana...

Carbon Dioxide Capture and Hydrogen Purification from Synthesis Gas by Pressure Swing Adsorption

Global warming has become more and more serious, which is caused by greenhouse gases. Cutting down the emission of CO2 has already become one of the major research target in the world. This study utilized a pressure swing adsorption (PSA) process to separate high-purity hydrogen and to capture CO2 from synthesis gas, which is the effluent stream of water-gas-shift reactor. The purified H2 can b...
