Hydrogen-Rich Syngas Production from Gasification and Pyrolysis of Solar Dried Sewage Sludge: Experimental and Modeling Investigations.

Solar dried sewage sludge (SS) conversion by pyrolysis and gasification processes has been performed, separately, using two laboratory-scale reactors, a fixed-bed pyrolyzer and a downdraft gasifier, to produce mainly hydrogen-rich syngas. Prior to SS conversion, solar drying has been conducted in order to reduce moisture content (up to 10%). SS characterization reveals that these biosolids could be appropriate materials for gaseous products production.

Production and characterization of bio-oil from the pyrolysis of waste frying oil.

In this present work, the disposal of waste frying oil was explored. The experiment tests were performed under nitrogen (N) atmosphere at 5 °C/min heating rate from the ambient temperature to 500 °C. In these operating conditions, the obtained pyrolitic liquid fraction was 76 wt% formed by 63.
