A catalyst-free process for gas ozonation of reduced sulfur compounds

Abstract

Feasibility of gas ozonation of RSCs was investigated for industrial application.• Whereas H 2 S was removed up to 80%, MES and DMDS were weakly removed by ozone.• SIFT/MS was used to measure RSCs concentrations and to calculate their removals.• Primary products generation of RSCsozone reaction were determined by SIFT/MS.

Tuning Interaction and Diffusion for Dimethyl Disulfide Adsorption on Cu-BTC Frameworks via Low Transition-Metal Doping

“…All samples were characterized using multiple techniques. Considering the high removal difficulty of disulfides from light hydrocarbons because of the low reactivity of disulfide compounds, , we performed the adsorption measurement using DMDS as the adsorbate to examine the adsorption performances of synthesized samples. Combined with computational simulation, the influences of low metal doping on structures and DMDS adsorption are discussed carefully.…”

Enhanced Biodesulfurization with a Microbubble Strategy in an Airlift Bioreactor with Haloalkaliphilic Bacterium Thioalkalivibrio versutus D306

“…This is an important problem, resulting in high costs of catalyst regeneration and replacement. Moreover, H 2 S separation and control processes are necessary to reduce the pollution before releasing it into the environment. − Generally, there are systematic approaches, such as chemical processes, to remove and treat H 2 S in the industry, but these processes result in environmental issues and large amounts of energy consumption. An alternative route is biological desulfurization, also known as biodesulfurization; it is a more environmentally friendly option that reduces production costs and currently is generating considerable interest from the industry. − …”
