Effect of pyrolysis temperature on desulfurization performance of high organic sulfur low rank coal [PDF]

Journal of Mining and Metallurgy. Section A: Mining, 2021
The sulfur in coal not only influences the coke quality but also pollutes the environment during the combustion. The desulfurization of high organic sulfur coal is a key issue in coal cleaning science.

Organic sulfur: A spatially variable and understudied component of marine organic matter

Limnology and Oceanography Letters, 2020
Sulfur (S) is a major heteroatom in organic matter. This project evaluated spatial variability in the concentration and molecular‐level composition of organic sulfur along gradients of depth and latitude.

Effects of elemental sulfur and sulfur-bearing minerals on the thermal evolution of aromatic compounds in solid bitumen

Shiyou shiyan dizhi, 2021
Previous studies have shown that some of the aromatic compound parameters have good correlation with the maturity of organic matter. However, it is still unknown whether the widely used aromatic maturity-related parameters are available with the co ...

Modulating the sulfurization procedure to decrease by-product formation for one-step catalytic synthesis of sulfur-containing chemicals

Fuel Processing Technology
The one-step synthesis of sulfur-containing chemicals, methanethiol (CH3SH), from syngas and hydrogen sullfide (H2S) mixtures shows the enormous potential for extending the application of both C1 chemistry and sulfur resource recycling and utilization ...
