Abstract:

One of the important sulfur volatile organic molecules found in fossil fuels, especially natural gas, is ethyl mercaptan. Sulfur content should be kept as low as feasible in accordance with widely recognized international rules. One of the most promising methods for cleaning the environment and the economy is still the adsorption of pollutants or toxins. Although the affordability and simplicity of use make adsorption a very appealing and desired way of cleaning and separation, the choice of adsorbent determines or is crucial to the efficacy of adsorptive technology. For many years, a variety of industrial, environmental, and biological applications have used carbon and its modified forms, metal–organic frameworks, clays, zeolites, silica-based materials, and supported metal or metals as adsorbents. The major developments in various adsorbents for adsorptive desulfurization of sulfur compounds in fuels, natural gas, and crude oil are the main topic of this review.
