In Brazil, due to its availability, sugar cane bagasse has a high potential for power generation. The knowledge of ignition behavior, as well as the knowledge of the chemical kinetics, in of fuels combustion process is important features in boilers projects and in the stability of the combustion process control. The aim of this study is to investigate the thermal behavior of sugar cane bagasse,...

The non-isothermal thermogravimetric method (TGA) was applied to a bituminous coal (PT), two types of biomass, chestnut residues (CH) and olive stones (OS), and coalbiomass blends in order to investigate their thermal reactivity under steam. Fuel chars were obtained by pyrolysis in a fixed-bed reactor at a final temperature of 1373 K for 30 min. The gasification tests were carried out by thermo...

Abstract Shengdong coal was single-step and multi-step pyrolyzed by pyrolysis-gas chromatography/mass spectrometry. In the pyrolysis process, Mono-ring aromatics contents reach a maximum value at 800°C, while phenolic are significantly reduced, which might be attributed to dehydroxylation of phenolics. Naphthalene content also reaches 800°C in process; however, naphthalene not detected process....

This study explored the possibility of using upgraded coal and coke from Indonesian lignite in ironmaking process, specifically pulverized Injection (hereafter, “PCI”) carbon composite pellets material (sintering binder material). The found that (1) injection into blast furnace will have same effect as lime - heavy oil slurry furnace, combined infusion highly volatile matter low ash coal, flash...

With the development of society and industry, treatment disposal sludge have become a challenge for environmental protection. Co-pyrolysis is considered sustainable technology to optimize pyrolysis process improve quality performance products. Researchers investigated co-pyrolysis with other wastes, such as biomass, coal, domestic waste, in laboratories. has reduced energy consumption improved ...

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 ...
