Daftar Isi:
- Indonesia now is the largest producer of palm oil in the world. Over seven million hectares in the cultivation and more than 400 palm oil mills in operation. The major biomass byproduct from the palm oil industry is empty fruit bunches (EFB) that have a great potency as basic raw materials used for alternative energy. We have introduced a new technology for utilizing biomass waste for producing alternative energy (bio-gasoline, bio-kerosie and bio-solar) by combining pyrolysis-catalytic cracking-gasification processes in a whole system, namely as integrated autothermal technology. By using this technology, energy supplied to the system can be reduced significantly. In this study, pyrolysis of Indonesian oil palm empty fruit bunches (EFB) was investigated using a middle-scale slow pyrolysis. The products were bio-oil, char and gas. Then, bio-oil produced from this pirolysis can be used as feedstock for catalytic cracking. The effects of various pyrolysis temperatures, water content and different feedstock on the yields of the products were investigated. The temperature of pyrolysis and water content were varied in the range of 400-600°C and 13-18 %wt, respectively. The different feedstock was varied in the range of 500; 1,000; and 1,500 grams. The average heating rate was at 12oC min-1 to a final pyrolysis temperature. Product yields were found to be significantly influenced by the pyrolysis process conditions. Under the experimental conditions, the optimum bio-oil yield was 10.83 %wt obtained at 500°C, with water content of 18 %wt. While different feedstock has no significant effect on bio-oil yield. The maximum yield of char was 35.39 %wt, obtained at a pyrolysis temperature of 400°C, feedstock of 1000 grams. Meanwhile, the optimum yield of gas was 37.71 %wt, which could be achieved at a pyrolysis temperature of 450°C, feedstock of 1000 grams.
