Graded Solvation‐Structure Electrolyte for Synergistic Polysulfide Confinement and Interfacial Stabilization in Potassium‐Sulfur Batteries

Carbon Energy, EarlyView.
A graded solvation structure is designed through a strongly–moderately–weakly solvating strategy to synergistically regulate potassium polysulfide dissolution and K‐anode deposition behavior. This tailored electrolyte effectively stabilizes the electrode/electrolyte interphases and accelerates sulfur redox kinetics.

Investigation of hydrogen sulfide adsorption in metallic scaffold MOF-5 nanocomposite based on activated carbon for the use of respiratory mask cartridge

بهداشت و ایمنی کار, 2019
Introduction: Hydrogen sulfide is one of the most important impurities in natural gas. Due to the fact that this gas is hazardous, toxic, corrosive and volatile, therefore, the removal of hydrogen sulfide has been studied using several methods.

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Reversible Cystine Disulfide Scaffolding Enables Carbonyl Sulfide‐Mediated Intramolecular Peptide Bond Formation via Cyclocystine: Implications for Prebiotic Chemistry

Chemistry – A European Journal, EarlyView.
Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Composition of Purified CO2 From Steel Mill Processes—A Classification and Analytical Comparison With Commercial CO2

Chemie Ingenieur Technik, EarlyView.
Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.

On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal

Chemie Ingenieur Technik, EarlyView.
Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...
