“…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…”

“…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].…”

“…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].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
