synthetic slag process decreases sulfur and phosphorus contents of steel, improves inclusion removal, protects steel from atmosphere and prevents temperature drop of the liquid steel in the ladle. in this study, the synthetic slags of ternary cao-al2o3-sio2,and quaternary cao-al2o3-sio2-na2o and cao-al2o3-sio2-sro systems were pre-melted and then were kept in contact with the liquid steel in a ...

A compound catalyst (RA) consisted of Ni, ZnO and HZSM-5 with functions of reactive adsorption desulfurization (RADS) and olefin aromatization for fluid catalytic cracking (FCC) gasoline upgrading was prepared. X-ray powder diffraction (XRD), temperature-programmed reduction and low-temperature N2 adsorption were used to characterize the properties of the catalysts. Performance evaluation by FC...

1-C and 2-C-branched carbohydrates are present as substructures in a number of biologically important compounds. Although the synthesis of such carbohydrate derivatives is extensively studied, the synthesis of 1,2-cis-2-C-branched C-, S-, and N-glycosides is less explored. In this article a synthetic strategy for the synthesis of 1,2-cis-2-C-branched-aryl-C-glucosides is reported via a hydrogen...

Desulfurization of fossil fuels demands a high technology as the crude oil is very complex mixture of molecules with a largest hydrocarbons form in composition. Hydrogenic method for desulfurization, takes higher cost and energy and also sulfur is not separated completely from heterocyclic poly-aromatic compounds. Researchers are focused on the use of microbial desulfurization [Biodesulfurizati...

This study shows the ability of sodium humate from alkaline treatment sludge on removing sulfur dioxide (SO2) in the simulated flue gas. Experiments were conducted to examine the effect of various operating parameters, like the inlet SO2 concentration or temperature or O2, on the SO2 absorption efficiency and desulfurization time in a lab-scale bubbling reactor. The sludge sodium humate in the ...
