Feb 12, 2018· The calcination temperature of BCZT powders could be reduced to 800 °C. This could be attributed to sol–gel process, by which high activity powders were usually obtained at a low calcination temperature. Also, this was related to the organic raw material used in this work. At this temperature, the obtained BCZT powders were cubic phase ...
Apr 15, 2008· Abstract. Thermochemical equilibrium calculations indicate the possibility of considerable fuel savings and CO{sub 2} emission avoidance in the three steps of the Pidgeon process: (a) calcination of dolomite; (b) production of ferrosilicon from quartz sand, coal, and iron oxide; (c) silicothermic reduction of calcined dolomite by ferrosilicon to magnesium.

A process is described for increasing the efficiency of para-xylene production using a two stage isomerization sequence. In the first stage of the process, a C9+ aromatics feedstock is subjected to ethylbenzene conversion and xylene isomerization. Non-C¿8? aromatics are removed from the effluent, which is then processed in a second stage of the process to remove para-xylene and isomerize the ...
