Pyrolysis of agriculture wastes for bio-oil and char production

•Pyrolysis of agricultural wastes at 500 °C for 15 min produced bio-oil and bio-coal.•Produced bio-oil can be used as it is in electrical generating station.•Bio-chars produced are suitable for carbon sequestration or long term storage CO2 for green house climate change.

This investigation deals with pyrolysis of seven different agriculture wastes. The produced liquid, char were quantified and determined the quality of each of them.Pyrolysis experiments were carried out in a bench scale tubular furnace reactor. For characterization, oil phase was analyzed by gas chromatography (GC/MS) and its calorific value was determined while produced char was subjected to elemental analysis and calorific values of solids were also calculated from elemental analysis results.Experimental results show that jatropha seeds gave highest weight percent of bio-oil with highest heating value (HHV) while on the other hand date stone produced relatively high weight percent of char with highest heating value.So we can say agricultural wastes have good potential for alternative fuel production by pyrolysis.
