A pyroscrubber is the device used in petroleum coke Calcining industry to oxidize the carbonaceous contents, including hydrocarbon volatiles of the exhaust gas from the calcination kiln, so as to recover energy to produce electricity and leave no more than small traces of unburned volatiles, solid carbon, ashes, or emissions (e.g. CO, NOx and SOx) in the flue gas finally discharged. Motivated b...
In this research, the starting precursor material is metakaolin, which was obtained by calcining domestic kaolinite clay. Thermodynamic parameters: densities, viscosities, speed of sound and refractive index four series alkaline activatorswere determined over temperature range from 15 to 60oC process geopolymerization. The samples were characterized X-ray diffraction (XRD), FTIR Raman Spectrosc...
a facile co-precipitation method for the synthesis of well-dispersed ndfeo3 nanocrystals is developed in the presence of octanoic acid as surfactant. co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. the product is characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microsc...
A general approach has been designed to blue, green, and red pigments by metal ions doping hollow TiO(2). The reaction involves initial formation of PS at TiO(2) core-shell nanoparticles via a mixed-solvent method, and then mixing with metal ions solution containing PEG, followed calcining in the atmosphere. The as-prepared hollow pigments exhibit uniform size, bright color, and tunable density...
Influence of calcining temperature on formation of the high-Tc phase in the Bi-Pb-Sr-Ca-Cu-O system.
In this work we have prepared nano-sized Bi-YIG powders, using mechanochemical processing. In this process, a part of the activation energy, which is necessary for chemical reactions, is provided by high-energy mills. The as milled powders obtained by this technique need a lower annealing temperature in comparison with those obtained by conventional ceramic technique to become a single phase ga...
