Effects of magnetic fields on improving mass transfer in flue gas desulfurization with a fluidized bed are investigated in the paper. In this research, the magnetically fluidized bed (MFB) is used as the reactor in which ferromagnetic particles are fluidized with simulated flue gas under the influence of an external magnetic field. Lime slurry is continuously sprayed into the reactor. As a cons...

The biological oxidation of ferrous to ferric ion by iron oxidizing bacteria is potentially a useful industrial process for the removal of H2S from industrial gases, desulphurization of coal, and removal of sulfur dioxide from flue gas. In the bioprocess of H2S removal an aqueous Fe2(SO4)3 solution is used as an absorbent. H2S is absorbed and oxidized to elemental sulfur. At the same time, Fe i...

mixed-addenda vanadium substituted polyoxometalate supported on anatase tio2 crushed nano leaf was synthesized by an unusual reaction with titanium tetraisopropoxide at 100 ºc via sol–gel method under oil-bath condition. the materials characterized by xrd, tem,  ir and uv–vis  techniques.  in  the  present  work,  efficient  oxidative  of  thiols  with  polyoxometalate-tio2/hydrogen  peroxide  ...

Organosulphur compounds can be easily and selectively oxidized to sulfones using a small excess of Oxone(®) (1.6 eq.) under solventless mechanical milling conditions. This green procedure has been efficiently applied to a series of model compounds and to the desulphurization of medium/high sulphur content paraffins (up to 3000 mg kg(-1)).

Industrial coal combustion ashes as well as laboratory-scale experiments were used for the evaluation whether CaO, Al2O3 and Fe2O3 can help with the retention of volatile and acid-forming elements (S, Cl, Br, As and Se). Both industrial ashes evaluation and laboratory combustion experiments lead to the conclusion that CaO can efficiently help with the capture of not only S, but also of Cl, Br, ...
