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...

The incorporation of several industrial wastes in ceramic matrixes had been attempted as an effective low expense technique for the fixation of metallic species in usable products or simply to reduce the residue volume for further disposal. However, the dominant mechanism of the inertization process and the relevant influent parameters are still unknown, mostly due to the complexity of the syst...

The current investigation demonstrates that it is possible to molecularly design supported niobium oxide catalysts with the assistance of molecular characterization methods such as Raman spectroscopy. The formation and location of the surface niobium oxide species are controlled by the surface hydroxyl chemistry, and the surface niobium oxide species are located in the outermost layer of the ca...

Thin layers of titanium dioxide were fabricated by direct inkjet patterning of a reverse micelles sol-gel composition onto soda-lime glass plates. Several series of variable thickness samples were produced by repeated overprinting and these were further calcined at different temperatures. The resulting layers were inspected by optical and scanning electronic microscopy and their optical propert...

A novel design of combustion catalysts is proposed, in which clay/TiO₂/MnAl-mixed oxide composites are formed by intermixing exfoliated organo-montmorillonite with oxide precursors (hydrotalcite-like in the case of Mn-Al oxide) obtained by an inverse microemulsion method. In order to assess the catalysts' thermal stability, two calcination temperatures were employed: 450 and 600 °C. The composi...

Synthesis of an inorganic molecularly imprinted polymer (MIP) composed of tetraethoxysilane (TEOS) for recognize sulfonamides using a sol-gel process have been developed. The template, sulfamethazine (SMZ), was dissolved in acid aqueous solution and added into TEOS to formed the precursor solution and adjusted the pH by various ammonium hydroxide (NH4OH) and reacted for 3 days. After the reacti...

spherical granules of the superionic conductor β/β́ lizr2(po4)3 in the range of sub 100 nm sizewere synthesizedvia freeze drying methodand fully reviewed in all aspects. samples were characterized by the x-ray diffractometry (xrd), the thermal analysis (tg, dsc), thefourier transform infra-red spectroscopy (ftir) and the scanning electron microscopy (sem).their structuredepends largely on the me...

Manganese oxides are one of the most important groups of materials in energy storage science. In order to fully leverage their application potential, precise control of their properties such as particle size, surface area and Mn (x) (+) oxidation state is required. Here, Mn3O4 and Mn5O8 nanoparticles as well as mesoporous α-Mn2O3 particles were synthesized by calcination of Mn(II) glycolate nan...

Introduction Heat transport in particulate materials is an essential component of modern technologies such as high performance cryogenic insulation, heterogeneous catalytic reactors, construction material and powder metallurgy. In catalyst manufacturing, heat transfer through granular media occurs in the drying and calcination stages. In this paper, we describe experiments and particle dynamics...

The current research was focused on synthesizing potassium sodium niobate (KNN) piezoelectric ceramics for the system (K0.48Na0.52) NbO3   by high energy ball milling process for 15h at the speed of 300 rpm.  The blended nano-crystalline powder was calcined in conventional box furnace at 700oC, 800oC and 900oC for duration of 5h, 7h and 10h.  Diffraction result of calcine powder confirmed the f...
