In the Boudouard reaction, where CO2 is reacted with carbon (char) to produce CO, very high temperatures are required to shift the equilibrium towards CO production. This endothermic reaction is inherently slow and catalytic species are effective to speed up the reaction rate at temperatures below 900 °C. In this study, the catalytic effect of some alkali (K, Na), alkaline earth (Ca) and transi...

The effect of basic magnesium carbonate (BMC), magnesium hydroxide (MH), and magnesium chloride hydrate (MCH) on thermal degradation of red gum wood was studied using cone calorimetry, Thermogravimetric-differential scanning calorimetry (TG-DSC) analysis, and X-ray diffraction (XRD) characterization. The results showed common fire retardation actions of the three compounds by releasing incombus...

The depletion of phosphate rock reserves has led to the search for new, alternative and environmentally friendly products processes. One safe sources is animal bone char (ABC), residue from pyrolysis meat meal (MBM), a slaughterhouse waste material. presented study investigated physico-chemical properties residues (ABC) obtained MBM under different treatment conditions. Two end temperatures (60...

In this paper, effects of the operating pressure on ash formation reported in the open literature have been reviewed. In particular, the recent significant advances achieved at the Cooperative Research Centre for Coal in Sustainable Development (CCSD) in Australia are highlighted. The operating pressure significantly influences the size and the chemistry of ash generated through its effects on ...

Experiments have been conducted to study the controlling mechanisms involved in the transition from smoldering to flaming of a porous combustible material, flexible polyurethane foam, with an air flow forced across one of the porous-fuel surfaces. The experiments are performed in a small-scale, vertical, combustion wind tunnel, with the air flow forced upward and parallel to an exposed foam sur...
