Summary: | Recently, owing to environmental and economic considerations, interest in utilizing
biomass for the production of energy and chemicals is increasing. Palm oil shell wastes are
one of the main agriculture waste in Malaysia. Pyrolysis is one of the most promising thermochemical
techniques for recovering energy from biomass. Pyrolysis of oil-palm shell waste
was first carried out using thermogravimetric analysis (TGA). The effects of heating rate on
the pyrolytic properties were investigated. The kinetic parameters have also been determined
using integral method. This paper also describes the experimental results from a bench-scale
circulating fluidized-bed (CFB) test rig, installed at SIRIM Berhad, Shah Alam, suitable for
gasification and combustion experiments using different biomass materials. The purpose of
the tests was to investigate the suitability of the selected fuels for energy production using
Circulating Fluidised Bed Combustor (CFBC) while taking care of the flue gas emissions.
Operating parameters (such as temperature, type of biomass, feeding rate, heating rate,
pressure, primary air and reactor configuration) are believed to influence significantly the
pyrolysis of a biomass. Temperature is one of the most important operating variants so the
experimental studies were done to investigate the influence of temperature on pyrolysis. the
concentrations of CO, NOx and CO2 in the flue gas were measured. The combustion
performances were evaluated by varying the primary gas flow through the CFBC tubular
furnace. the emission of NOx ranged from 38–75 ppm while the CO emissions were high for
higher primary air flow rates.
