Desulfurizer-Enhanced Carbothermal Reduction of MoS2 to Synthesize Mo2C

A novel sulfur‐emission free route for preparing ultrafine MoSi2 powder by silicothermic reduction of MoS2

“…Modeling of infiltration of liquids in porous media is a well-studied subject, especially in the field of hydrology where it is used to model seepage of water through porous soils and rocks. 29,30 The physics of resin flow into a mold under pressure is similar to the seepage problem and so similar approaches have been used also to model the flow of resin into a mold containing fiber mats. 23,[31][32][33][34][35][36][37][38] The models are used in these cases to determine the resin flow front and mold filling times corresponding to different infiltration conditions.…”

“…Many reports demonstrated that Mo, Mo 2 C, or their mixture could be prepared by lime-assisted reduction with reducing agent of H 2 , C, or CH 4 . 25,[27][28][29] In those studies, lime was uniformly mixed with MoS 2 for the purpose of desulfurization, and finally the mixed products of Mo, Mo 2 C, or their mixture with the by-product CaS and unreacted CaO were obtained. However, it is difficult to separate the Mo-containing products from the sulfide-containing by-products in an environmentally way due to both acidic leaching and water leaching will release sulfur-containing gas and cause environmental pollution.…”

Study on preparation and properties of supported compound desulfurizer for Bayer dissolution

“…This paper focuses on the preparation and desulfurization of in wet process desulfurization, and also puts forward related requirements for desulfurizer in view of the problems in dissolution process, such as high activity, high sulfur capacity, fast reaction speed, stability and easy to control the side reaction [7]. The results of Westmoreland and Harrison's thermodynamic study of a series of sulfidation reactions of 28 metal oxides at medium and high temperatures showed that oxides of 11 metals can be used for desulfurization [8], namely Ba, Ca [9], Co, Cu [10], Fe [11], Mn, Mo, Sr, W, V and Zn. The oxides of these metals have the ability to desulfurize at medium and high temperatures and are easily regenerated.…”
