Perspectives on strategies for improving ultra-deep desulfurization of liquid fuels through hydrotreatment: Catalyst improvement and feedstock pre-treatment

open access: yesFrontiers in Chemistry, 2022
Reliance on crude oil remains high while the transition to green and renewable sources of fuel is still slow. Developing and strengthening strategies for reducing sulfur emissions from crude oil is therefore imperative and makes it possible to ...

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

open access: yesFuel 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 ...

Sulfur-bound biomarkers of a Monterey shale and a Greenland lake sediment

open access: yes, 2009
Seeking to reconstruct the biogeochemical processes that produced organic sulfur compounds in two unique depositional environments, we used the nickel boride desulfurization reaction to release hydrocarbons from sulfur-bound macromolecules not otherwise ...

Effects of plant sulfur nutrition on acrylamide and aroma compounds in cooked wheat

open access: yes, 2008
Wheat flour from plants deficient in sulfur has been shown to contain substantially higher levels of free amino acids, particularly asparagine and glutamine, than flour from wheat grown where sulfur nutrition was sufficient. Elevated levels of asparagine

Molecular interaction between N-butylpyridinium tetrafluoroborate and cyclic sulfur compounds: A DFT study

open access: yesJournal of Ionic Liquids
Extraction of sulfur compounds from crude oil is one of the problems of industries related to crude oil. The use of ionic liquids (ILs) as a green solvent to extract these sulfur compounds, especially cyclic sulfur compounds, can be considered a ...
