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...

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,...
