Kinetics and mechanism of phase transfer catalyzed synthesis of aromatic thioethers by H 2 S-rich methyldiethanolamine

Nanolayered cobalt–molybdenum sulphides (Co–Mo–S) catalyse borrowing hydrogen C–S bond formation reactions of thiols or H2S with alcohols

“…Nowadays, the emission of the H 2 S produced in most of the refineries is commonly mitigated through the conventional Claus process, which converts this harmful gas into elemental sulphur 29. However, the consumption of sulphur relative to its current production is too high, and therefore the development of new methodologies to transform H 2 S into valuable and more in-demand products is highly desirable 30…”

Hydrogen sulfide capture and removal technologies: A comprehensive review of recent developments and emerging trends

“…Conversion of captured H 2 S directly to value-added chemicals is another pathway to circular economy. For example, a multiphase reactor using phase transfer catalysis could potentially replace the expensive regeneration column in the alkanolamine-based absorption process and convert dissolved H 2 S to dibenzyl sulfide bypassing the need for a sulfur recovery unit [482]. This could have a huge impact on the overall economics and sustainability of H 2 S removal processes [483].…”

Recently developed applications for natural hydrophilic polymers

“…Large quantities of nickel and sulfur in crude oil make the refining process heavier; unfortunately, the current conventional processes to remove these materials require a significant investment and long reaction times [188][189][190][191]. Wang et al Chitosan compounds have also been used as oxidants [193][194][195][196][197][198][199].…”
