As the world's second largest producer of palm oil, Malaysia has more than four million hectares of its land cultivated with oil palm trees. The palm oil industry produces millions of tons of biomass annually, in which mostly are underutilized and of no value. With Malaysia's recent effort in promoting renewable energy through the launching of its National Green Technology Policy, oil palm biomass has since been actively studied for its potential as a green and renewable energy source. The Downdraft Gasification of Oil Palm Frond explores into the feasibility of oil palm frond to be utilized as fuel to produce heat and electricity. Readers will gain insight into the overview of the biomass, the underlying principle of gasification technology, as well as the valuable outcomes from the gasification of oil palm frond. Intended for researchers, engineers and technology enthusiasts alike, it is the hope of the authors that the book will be beneficial for readers to gain as much about the centuries-old gasification technology and that the oil palm frond to be valued as one of the most promising sources of alternative fuel in the near future.
