Abstract

The purpose of this work is to reuse bleached clay. It is used to produce pellet fuel with oil palm fronds and reactivation (microwave pyrolysis and acid activation) to be re-bleaching in the crude palm oil refining industry. In the production of pellet fuel, a torrefaction process is used to increase the fuel properties of oil palm fronds by using a microwave torrefactor result, torrefaction at 300oC for 20 minutes is the most suitable torrefaction condition due to its highest reliability and increased carbon stability. net calorific value and fixed carbon were 23.01 MJ/Kg and 46.06% respectively when used to produce pellet fuel together with used bleaching clay, it was found that the greater the amount of palm passage, the higher the calorific value of the pellet fuel both non- torrefied pellet fuel and torrefied pellet fuel have calorific values of 12.24 MJ/Kg and 18.40 MJ/Kg. respectively The calorific value of torrefied pellet fuel between oil palm fronds torrefied and used bleaching soil in the ratio of 70:30 is the highest and meets the benchmark ISO/TS 1 7 2 2 5 - 8 :2 0 1 6 Solid biofuels — Fuel specifications and classes (Part 8: Graded thermally treated and densified biomass fuels). In terms of reactivation, used bleaching clay. When analyzing the surface area and pore volume of pyrolysis used bleaching clay and pyrolysis used bleaching clay followed by acid activation. It becomes clear that pyrolysis used bleaching clay followed by acid activation has increased surface area and pore volume from pyrolysis used bleaching clay. But in comparison with pure bleaching clay. It was found that the surface area and pore volume of reactived bleaching clay were found to be both pyrolysis treated used bleaching clay and pyrolysis used bleaching clay followed by acid activation. It is less valuable than pure bleached clay. This is consistent with the effect of crude palm oil bleaching color values that showed lower pigmentation values of oil bleached with pure bleaching clay. The color value of the oil bleached with reactived bleached clay, both pyrolysis and pyrolysis followed by acid activation.
