Analysis of the Synthetic Gas Production from Saw Dust Gasification

Aims: Produce combustible gas from sawdust for domestic house use.

Study Design: A fluidized bed gasifier suitable for sawdust gasification was used.

Place and Duration of Study: The study was done at the federal university of technology akure, Ondo state Nigeria

Methodology: Sawdust was first processed by converting it to pellets. Tests were carried out on the pellets using a bomb calorimeter using the ASTM-E771 standard. On experimental, the pellets were loaded into the reactor and then fired. Air was forced into the plenum, after which the air distributor plate evenly distributed jets of air in the bed resulting in complete and incomplete combustion.

Results: Experimental tests showed that the pellets have a heating value of 16.36 MJ of energy per kg and a higher percentage of volatile matter of 57.62% (ASTM-E872) and a lower percentage of fixed carbon than the initial sawdust sample. The produced synthesis gas composed of methane 63.4%, Ammonia 1.09%, Carbon monoxide 0.63%, Hydrogen sulphide 0.84% and carbon dioxide 34.04%.

Conclusion: The gas was ignited showing it was combustible.
