Kinetics of co-pyrolysis of sawdust, coal and tar [PDF]
Bioresource Technology, 2016 Two coals, sawdust and coal tar were selected to prepare briquettes. Thermogravimetric analyses at three heating rates (i.e. 10, 20 and 30°C/min) and up to 1000°C were carried out with the briquette components. Four blends were prepared and the experimental decomposition profiles were compared with the calculated data taking into account the amount of ...

Experimental Research of Heterogeneous Cracking of Pyrolysis Tars
Chemical Engineering Transactions, 2014 Biomass is the largest and the most important renewable energy source in the world. World production of biomass is estimated at 150–200 billion metric tons a year. Currently biomass provides approximately 14% of the total world energy consumption. The most effective way to convert biomass into energy is its conversion into combustible gas. However, the

Hydroconversion of coal tars: effect of the temperature of pyrolysis on the reactivity of the tars
Fuel Processing Technology, 1988 Abstract The hydroconversion of a low-temperature and of a high-temperature tar was carried out in the presence of a sulfided Ni and Mo on alumina catalyst — pure or mixed with an acid catalyst (HY zeolite). Significant amounts of light products can be obtained from low temperature tar, formed however through a non-catalytic process. On the contrary,
