The worldwide demand for energy is ever escalating commensurate with increasing populations and development.
While fossil fuels as the current major energy resource are shrinking drastically, combustion of fossil
fuel releases greenhouse gases, which are the main culprit for global warming and climate changes. Development
of renewable energy appears to be a prominent solution to address these energy and environmental issues. Pyrolysis
process converting biomass into energy offers a promising alternative for renewable energy supply. This paper
reviews recent and state-of-art development of biomass pyrolysis research in producing biochar, bio-oil and biogas.
Factors affecting pyrolysis processes and intrinsic properties of the pyrolysis products produced from different operating conditions are
discussed. Advancement in pyrolysis technology as well as the challenges and prospects of pyrolysis for energy production are also outlined.
Keywords: Biochar, biogas, biomass, bio-oil, co-pyrolysis, pyrolysis, renewable energy.
