Malaysia has about 4.2 million hectares of oil palm plantation. The palm oil milling industry has over 400 mills throughout the country with total milling capacity of 82 million tonnes fresh fruit bunches, FFB, per year. In 2003, the amount of FFB processed was 67 million tonnes, which generated solid wastes in the forms of empty fruit bunches, EFB (19.43 million tonnes), mesocarp fibres (12.07 million tonnes) and palm kernel shell (4.89 million tonnes). These wastes has moisture content of 60–70% for EFB and mesocarp fibre, and 34–40% for palm kernel shell, and calorific value of 5.0 – 18.0 Mj/kg. A processing technology was developed to process these low quality biomass fuels into high quality solid biofuel briquettes with moisture content in the range 8–12%. Depending on the formulations and the sources of the raw biomass, the final solid biofuel briquettes can have calorific values in the range of 18–25 Mj/kg. The production of the solid biofuel briquettes would be an attractive financial advantage for full exploitation of biomass fuels. Logistic problems due to the disperse nature of the biomass resources would significantly be addressed.

Palm oil production in Malaysia has increased over the years. As the consequence of high production of palm oil, surplus quantities of palm oil biomass wastes such as empty fruit bunches (EFB), palm kernel shell (PKS), and oil palm decanter cake (DC) are generated. Generally, these wastes are used as fuel to generate steam for boilers, which end up as ash. As several agricultural wastes are well-known to be rich in silica content, this study aims to investigate the bio-silica content of EFB, PKS and DC and their characteristics when calcined at various calcination temperatures from 400°C to 800°C. Several analyses were conducted such as weight loss, color, BET, SEM and FTIR. The results have shown that all samples favorably exhibited silica at higher temperatures, i.e., 800°C. Color analysis depicted that combustible elements were mostly removed at 800°C, leaving non-combusted silica in the waste ash. Weight loss analysis presented that EFB achieved the highest weight loss at 99.05%, followed by PKS at 95.65% and DC at 83.95%. This led to a relatively high amount or purity of silica in the sample. BET analysis showed highest surface area, 20.087m2/g (PKS) and the lowest is 9.492m2/g (DC) at 800°C which verified the high porosity of samples for further absorption applications. The presence of silica was also significantly observed in 800°C FTIR spectra for all waste samples. Overall, it is concluded that EFB, PKS, and DC are highly potential wastes to contribute to the production of bio-silica, which thus can be an option to overcome waste disposal issues in palm oil industries.

West Java has the potential of palm oil wastes such as empty fruit bunches (EFB) and palm kernel shell (PKS) that can be used for fabrication of briquettes as raw materials. Briquette as a solid fuel and as a substitute for fossil fuel must have a good quality to be accepted in the market, such as having a good thermal and good physical properties. This research, reviewing the effect of particle size parameter and the effect of adding adhesive on briquette to heating value, thermal properties and physical properties. Briquettes were determined by using varying EFB and PKS biomass ratios of 50:50 and by adding 7% adhesive from tapioca flour or molasses of the total mass of the briquette. Particle size variations are set for 20 mesh and 40 mesh. The best heating value was found at 5,898 cal/g in the sample briquette by using 40 mesh particle and tapioca flour adhesive. The thermal properties test shown the combustion rate of 0.34 g/minutes and combustion lenght of 111 minutes found in 40 mesh briquette sample by using tapioca flour adhesive. The physical properties test shown the best density value of 0.215 g/cm3 and shattering resistance of 66,23% found in the 40 mesh briquette sample by using tapioca flour adhesive. The best durable value found in sample briquette with 20 mesh particle with tapioca flour adhesive which is 54.35%. The result was indicated that briquette with 40 mesh particle size and tapioca flour adhesive gives the best result of heating value, thermal properties and physical properties

Fluidized Bed Combustor

Combustion efficiency is one of the most important parameters especially in the fluidized-bed combustor. Investigations into the efficiency of combustion in fluidized-bed combustor fuels using solid biomass waste fuels in recent years are increasingly in demand by researchers around the world. Specifically, this study aims to calculate the combustion efficiency in the fluidized-bed combustor. Combustion efficiency is calculated based on combustion results from the modification of hollow plates in the fluidized-bed combustor. The modified hollow plate aims to control combustion so that the fuel incorporated can burn out and not saturate. The combustion experiments were tested using palm oil biomass solid waste fuels such as palm kernel shell, oil palm midrib, and empty fruit bunches. The results of the measurements showed that the maximum combustion temperature for the palm kernel shell fuel reached 863 °C for M1 and 887 °C for M2. The maximum combustion temperature measurements for M1 and M2 from the oil palm midrib fuel testing reached 898 °C and 858 °C, respectively, while the maximum combustion temperature for M1 and M2 from the empty fruit bunches fuel was 667 °C and M2 847 °C, respectively. The rate of combustion efficiency with the modification of the hole plate in the fluidized-bed combustor reached 96.2%. Thermal efficiency in fluidized-bed combustors for oil palm midrib was 72.62%, for PKS was 70.03%, and for empty fruit bunches was 52.43%. The highest heat transfer rates for the oil palm midrib fuel reached 7792.36 W/m2, palm kernel shell 7167.38 W/m2, and empty fruit bunches 5127.83 W/m2. Thus, the modification of the holed plate in the fluidized-bed combustor chamber showed better performance of the plate than without modification.

Carbon dots (CDs), a nanomaterial synthesized from organic precursors rich in carbon content with excellent fluorescent property, are in high demand for many purposes, including sensing and biosensing applications. This research focused on preparing CDs from natural and abundant waste, palm kernel shells (PKS) obtained from palm oil biomass, aiming for sensing and biosensing applications. Ethylenediamine and L-phenylalanine doped CDs were produced via the hydrothermal and solvothermal methods using one-pot synthesis techniques in an autoclave batch reactor. The as-prepared N-CDs shows excellent photoluminescence (PL) property and a quantum yield (QY) of 13.7% for ethylenediamine (EDA) doped N-CDs (CDs-EDA) and 8.6% for L-phenylalanine (L-Ph) doped N-CDs (CDs-LPh) with an excitation/emission wavelength of 360 nm/450 nm. The transmission electron microscopy (TEM) images show the N-CDs have an average particle size of 2 nm for both CDs. UV-Visible spectrophotometric results showed C=C and C=O transition. FTIR results show and confirm the presence of functional groups, such as -OH, -C=O, -NH2 on the N-CDs, and the X-ray diffraction pattern showed that the N-CDs were crystalline, depicted with sharp peaks. This research work demonstrated that palm kernel shell biomass often thrown away as waste can produce CDs with excellent physicochemical properties.
