Adsorptive desulfurization of diesel by regenerable nickel based adsorbents

Effects of alumina phases as nickel supports on deep reactive adsorption of (4,6-dimethyl) dibenzothiophene: Comparison between γ, δ, and θ-alumina

“…SO 2 evaluation profile showed a peak at 713 K. Furthermore, this observation showed that a threshold temperature of about 713 K was required to oxidize the adsorbed sulfur species and remove them from the adsorbent surface before it could be reused for the subsequent reduction and adsorption steps. This agrees well with the TPO results reported by Dasgupta et al [52]. As is seen in Fig.…”

A Review on Desulfurization Techniques of Liquid Fuels

“…Souman Das Gupta et al [29] reported adsorptive desulfurization of diesel by used of nickel-based adsorbent. The investigators reported that under optimized conditions (pressure 4 bar and temperature 350°C) nickel based adsorbent(NiMCM-41) could reduce the sulfur concentration from 450ppm to 50ppm.…”

A vapor phase adsorptive desulfurization process for producing ultra low sulphur diesel using NiY zeolite as a regenerable adsorbent

“…In continuation of our earlier work [24,25,26] on adsorptive desulphurization process development, in the present work we have studied feasibility of ultra deep desulfurization of a low sulphur (50 ppm) commercial diesel using a zeolite based vapor phase adsorption process.…”

“…A simplified schematic of the unit has been reported in our earlier publications[25,26]. The unit has the provision of in situ thermal regeneration/activation of spent adsorbent under oxidizing and reductive atmosphere.…”
