The so-called micro fluidized bed reaction analyzer (MFBRA) and a thermogravimetric analyzer (TGA) were adopted to comparatively investigate the non-isothermal gasification of coal char with CO2. Experimental results demonstrated that heating rate obviously affected the coal char gasification reaction. Raising heating rate evidently increased the temperatures at the initiating reaction (Ti), the maximal...
Polyhydroxybutyrate (PHB) is an energy storage material formed from renewable feedstock in many bacterial species. The biopolyester (C4H6O2)n was degraded, deoxygenated and reformed into hydrocarbon oil (C6–C18) on solid phosphoric acid (SPA) in one-pot reaction. The reaction started at 213°C and completed below 240°C as measured with a differential scanning calorimeter. In addition to the oil, other...
In order to improve leaching efficiency of vanadium pentoxide (V 2 O 5 ) from stone coal and to reduce its connected environmental pollution, this article investigated the oxidizing roasting of stone coal in a laboratory fluidized bed reactor to optimize the roasting method and conditions. The examined parameters included reaction temperature, reaction time and amount and mixing method...
The isothermal differential characteristics of the gas–solid reaction occurring in a micro-fluidized bed reactor were studied using the indigenously developed Micro-Fluidized Bed Reaction Analyzer (MFBRA). The combustion of graphite powder in micrometers was taken as the model reaction because of its negligible internal diffusion and chemical-reaction simplicity. With minimized inhibitions from both...
