A Medium-Scale 50 MWfuel Biomass Gasification Based Bio-SNG Plant: A Developed Gas Cleaning Process
Energies, 2015 Natural gas is becoming increasingly important as a primary energy source. A suitable replacement for fossil natural gas is bio-SNG, produced by biomass gasification, followed by methanation.

Organic sulfur was integral to the Archean sulfur cycle [PDF]
Nature Communications, 2019 AbstractThe chemistry of the Early Earth is widely inferred from the elemental and isotopic compositions of sulfidic sedimentary rocks, which are presumed to have formed globally through the reduction of seawater sulfate or locally from hydrothermally supplied sulfide.

, 2007 Sulfur is a necessary dietary component that can be toxic at excessive concentrations. Animal bodies are about 0.15% sulfur by weight ([NRC, 1988] and [NRC, 1998]). Sulfur is incorporated into many essential molecules, including biotin, chondroitin sulfate, cartilage mucopolysaccharides, co-enzyme A, fibrinogen, glutathione, heparin, lipoic acid ...

GEOCHEMICAL JOURNAL, 1966 Sulfur and sulfur compounds involved in the chemical reaction, 3H2SO3= 2H2SO4+S+H2O in the temperature range from 150 to 300°C have been quantitatively determined. After the disproportionation reaction of sulfurous acid is completed, sulfur decreases according to the chemical reaction, 4S+4H2O = 3H2S+H2SO4.

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...
