THESIS MUHAMMAD IDRIS

Abstrak

Climate change, global warming, and energy crisis are critical issues to be solved urgently in a global framework. Alternative energy and renewable energy technologies must be quickly developed to be substituted for fossil fuels like oil, gases, and coal. USA, UE, and Japan invested huge budgets to develop biomass renewable energy technology. Their target is to develop commercial base large-scaled plant. On the other hand, in developing countries, especially in rural areas, people who can access electricity is still less than 70%, To decelerate or prevent global warming, and improve electrification in rural areas, a new technology for wood pyrolysis, which requires low manufacturing cost and less maintenance, and of which gases are directly applicable to gas engine generator, was developed by the previous work. This work aims at understanding pyrolysis process in the pre-vacuum chamber in more detail and thus improving the plant performance, and carries out numerical analysis on the pyrolysis process taking into account fluid dynamics and chemical reaction inside the pre-vacuum chamber. The numerical results provide useful information to understand the pyrolysis process and to improve the plant performance.
