Assessment of olive wastes as energy source: pyrolysis, torrefaction and the key role of H loss in thermal breakdown

Volpe, Roberto; Messineo, Antonio; Millan, Marcos; … - In: Energy 82 (2015) C, pp. 119-127

The present work describes the first stage of a multi-stage process seeking to develop a usable and cheap design for a downdraft gasifier fed with lingo-cellulosic olive waste. The thermochemical behaviour of two types of olive waste has been assessed during pyrolysis and torrefaction...

Influence of FeCl3 and lime added to sludge on sludge–coal pyrolysis

Folgueras, M.B.; Díaz, R.M. - In: Energy 35 (2010) 12, pp. 5250-5259

Copyrolysis of sewage sludge–coal blends at different ratios (0:100, 10:90, 50:50 and 100:0) was investigated using a simultaneous thermogravimetry–mass spectrometry analyser. During copyrolysis three thermal decomposition stages were identified between 180 and 800°C. From 180°C to 385°C,...
