Pyrolysis and gasification of two different sludges coming from a Spanish refinery have been performed at different experimental conditions. A physico-chemical (PC) and a biological (BIO) sludge have been studied. Runs at different heating rates (approx. 4 and 10 K/s) and with different contact time between gases and decomposed sludge have been performed. In general, the ratio H2/CO is higher in pyrolytic runs. The highest ratio is obtained in the pyrolysis at low heating rate and parallel flow, using both sludges. The maximum emission of CO, i.e. the worst combustion conditions, is given in the runs where contact time is minimized and at high heating rates.
► Two different sludges from refinery wastewater are used.
► Pyrolysis and combustion are studied in a laboratory reactor at different conditions.
► Analysis of the gas evolved from all runs is given.
► Special attention is given to hydrogen and carbon monoxide production.
► Important differences were found in the gas produced at the different heating rates.
