This work presents a detailed kinetic modelling study of the thermal pyrolysis of tetraethoxysilane (TEOS). A chemical mechanism is proposed based on an analogy between the hydrocarbon branches attached to the central silicon atom and an existing mechanism for the decomposition and combustion of ethanol. Important reaction pathways are identified through element flux and sensitivity analyses. I...

in this study, we synthesis one-dimensional (1d) manganese(iii) schiff base coordination polymer [mn(brsalophen)(μ1,3-n3)]n by reaction of mncl2·6h2o and tetradentate schiff base ligand brsalophen at the presence of nan3 in methanol and characterized by elemental analyses (chn) and ft-ir spectroscopy. it was used as a new precursor to prepare spinel type manganese oxide nanowires by a facile so...

as a new precursor, [tris(2-hydroxyacetophenato) triaqua(iii)], [y(hap)3(h2o)3]; complex was used in thermal decomposition process for the synthesis of rod-like high-temperature ceramic ybco with length of about 320-350 nm and diameters 60–90 nm. the as-synthesized products were characterized by xrd, ft-ir, tem, sem and edx analyses. the results showed that by using fine raw materials, the calc...

Pyrolysis, a first step in the biomass gasification, is the thermal decomposition of organic matter under inert atmospheric conditions, leading to the release of volatiles and formation of char. In the proposed kinetic model of this study, the kinetic scheme of biomass decomposition by two competing reactions giving gaseous volatiles and solid charcoal is used. Four different models are propose...

Thermal decomposition kinetics of calcium carbonate was studied by non-isothermal thermogravimetric analysis at different heating rates. The reaction mechanism was found to follow a two-dimensional phase boundary-controlled model by modelfree and model-fitting methods. Two non-Arrhenius equations (Harcourt–Esson equation and Berthelot–Hood equation) were used to interpret the decomposition kine...

Pentanol is one of the promising "next generation" alcohol fuels with high energy density and low hygroscopicity. In the present work, dominant reaction channels of thermal decomposition of three isomers of pentanol: 1-pentanol, 2-methyl-1-butanol, and 3-methyl-1-butanol were investigated by CBS-QB3 calculations. Subsequently, the temperature- and pressure-dependent rate constants for these cha...
