Phosphorus as phosphate and nitrogen as ammonium or nitrate are the main nutrients in wastewaters and agricultural sludges. They runoff easily to waterways and cause eutrophication in water bodies. However, ammonium and phosphate could be precipitated simultaneously and used as recycled nutrients. In this research, dolomite calcined …
May 01, 2020· Dolomites become chemically active after being calcined at a temperature above 900 °C. The calcined dolomites are generally referred to as cracking catalysts with formula CaO.MgO. These oxides in calcined dolomite have the ability to eliminate tar by steam and dry (CO 2) reforming reactions, . As can be seen, from Eq. (1) and Eq.

Notes. Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns. This refractory work well for ladles because it creates MgO in solution in the slag, which provides an buffering because MgO particles ...

Calcined dolomites, limestones, and magnesites are active and inexpensive solids for cleaning raw hot gas from biomass gasifiers with steam. The variations of their activities with time-on-stream are studied here. Simultaneous coke formation and coke elimination by steam gasification increases the life of these "naturally occurring" catalysts under some circumstances.
