The effects of moisture content, fiber length and compaction time on African oil palm empty fruit bunches briquette quality parameters

Biomass wastes produced from oil palm mills and plantations include empty fruit bunches (EFBs), shells, fibers, trunks, and oil palm fronds (OPF). EFBs and shells are partially utilized as boiler fuel while the rest of the biomass materials like OPF have not been utilized for energy generation. No previous study has been reported on gasification of oil palm fronds (OPF) biomass for the production of fuel gas. In this paper, the effect of moisture content of fuel and reactor temperature on downdraft gasification of OPF was experimentally investigated using a lab scale gasifier of capacity 50 kW. In addition, results obtained from equilibrium model of gasification that was developed for facilitating the prediction of syngas composition are compared with experimental data. Comparison of simulation results for predicting calorific value of syngas with the experimental results showed a satisfactory agreement with a mean error of 0.1 MJ/Nm3. For a biomass moisture content of 29%, the resulting calorific value for the syngas was found to be only 2.63 MJ/Nm3, as compared to nearly double (4.95 MJ/Nm3) for biomass moisture content of 22%. A calorific value as high as 5.57 MJ/Nm3was recorded for higher oxidation zone temperature values.

Cutting Unit

Oil palm empty fruit bunches (OPEFB) are solid waste from the oil palm plantation industry with a fiber content of ± 70%, and can be used as a composite board reinforcement. From the results of previous studies found that the mechanical properties of composite boards of OPEFB fibers between the left, middle and right parts occur very large differences, this situation occurs because the length of the fiber used is not the same between 3-10 cm. The long fibers in addition to the adhesive mixing process are very difficult and long, also resulting in uneven strength of the boards on each side. The purpose of this study is to modify the design of the TKKS fiber chopping machine cutting unit using a reel type cutting cylinder, making the machine cutting unit, and testing the engine performance. From the results of engine design, the engine capacity is ± 85 kg / hour, the engine size is 110 cm x 36.5 cm x 49 cm, the motor power is 2.5 HP with a rotation of 1450 Rpm. The components of the chopper unit consist of the chopper holder measuring 8 cm x l5 cm x 13 cm, placed 3 pieces of planers which are 8 cm x 5 cm x 0.4 cm, the chopper shaft measuring 40 cm long and Ø 3 cm, the holder of the pin measuring Ø 16 cm with a thickness of 0.6 cm. From the results of engine performance testing, it is found that the capacity of the machine with 5 mm filter diameter is 35 kg / hour, diameter of 10 mm 48 kg / hour, diameter 15 mm 55 kg / hour and diameter of 20 mm is 65 kg / hour. The uniformity of the results in the filter hole 5 mm the average fiber length of 15-25 is 80%, the filter hole 10 mm fiber length an average of 30-40 mm by 82%, the filter hole 15 mm fiber length an average of 40-50 mm by 85%, and the filter hole 20 mm in fiber length an average of 50-60 mm by 80%.

Natural fiber-based hybrid composites with oil palm empty fruit bunches (EFB) and woven jute (Jw) fibers were prepared by hand lay-up method. Epoxy resin was used as matrix and tri-layer hybrid composites of EFB/ woven jute /EFB and woven jute /EFB/ woven jute were prepared by keeping the EFB/ woven jute fiber weight ratio constant at 4:1. The chemical resistance properties of the EFB/ woven jute/EFB and woven jute /EFB/ woven jute fiber-reinforced hybrid composites were studied by using three acids, three alkalies, and three solvents. It was found from the chemical resistance test that all the composites are resistance to various chemicals. It was observed that marked reduction in void content of composites with hybridization of oil palm EFB with woven jute fiber. Density and moisture content study demonstrated that density and moisture content property was enhanced in hybrid composites. The hybrid composites showed lower impact properties than pure EFB composite. Izod impact strength of EFB/woven jute/EFB and woven jute/EFB/woven jute hybrid was found to be 72.4 and 57.9 J/m, respectively. Impact fracture surface of the composites was studied with the help of scanning electron microscopy (SEM).

The study is aimed at investigating the thermal behavior and decomposition kinetics of torrefied oil palm empty fruit bunches (OPEFB) briquettes using a thermogravimetric (TG) analysis and the Coats-Redfern model. The results revealed that thermal decomposition kinetics of OPEFB and torrefied OPEFB briquettes is significantly influenced by the severity of torrefaction temperature. Furthermore, the temperature profile characteristics; Tonset, Tpeak, and Tend increased consistently due to the thermal lag observed during TG analysis. In addition, the torrefied OPEFB briquettes were observed to possess superior thermal and kinetic properties over the untorrefied OPEFB briquettes. It can be inferred that torrefaction improves the fuel properties of pelletized OPEFB for potential utilization in bioenergy conversion systems.

Strength Improvement

The potency of oil palm empty fruit bunches (OPEFB) fibers as one of the by-products of processing oil palm is increasing significantly so that proper management is needed in reducing environmental impact. One of the utilization of OPEFB fibers is as a substitution material in construction which usually the material is derived from non-renewable mining materials so that the number is increasingly limited. Therefore, it is necessary to study to know the performance of OPEFB fiber in making construction products especially concrete. In this case, the experiment was conducted using experimental method with variation of fiber addition by 0%, 10%, 15%, 20%, 25%, and 30%. Each specimen was tested by weight, slump value, compressive strength, tensile strength, elasticity and crack length. As the results, the variation of fibers addition by 10%, decrease of slump value is 7%, concrete weight is 3% and crack length is 8% while increase of the compressive strength is 2.7% and the modulus of elasticity is 33.3% but its tensile strength decreased insignificantly by 0.05% . Furthermore, the addition of fibers above 10% to 30% decreased compressive strength is still below 10% and tensile strength below 2% while the weight of concrete, slump value and crack length decreased. Therefore, the addition of 10% can replace the performance of concrete without fiber but the addition of above 10% can still be used on non-structural concrete.

Empty Fruit Bunches

Oil palm empty fruit bunches (OPEFB) fiber is a natural fiber that possesses many advantages, such as biodegradability, eco-friendly, and renewable nature. The effect of the OPEFB fiber loading reinforced fire retardant epoxy composites on flammability and tensile properties of the polymer biocomposites were investigated. The tests were carried out with four parameters, which were specimen A (constant), specimen B (20% of fiber), specimen C (35% of fiber), and specimen D (50% of fiber). The PET yarn and magnesium hydroxide were used as the reinforcement material and fire retardant agent, respectively. The results were obtained from several tests, which were the horizontal burning test, tensile test, and scanning electron microscopy (SEM). The result for the burning test showed that specimen B exhibited better flammability properties, which had the lowest average burning rate (11.47 mm/min). From the tensile strength, specimen A revealed the highest value of 10.79 N/mm2. For the SEM morphological test, increasing defects on the surface ruptured were observed that resulted in decreased tensile properties of the composites. It can be summarized that the flammability and tensile properties of OPEFB fiber reinforced fire retardant epoxy composites were reduced when the fiber volume contents were increased at the optimal loading of 20%, with the values of 11.47 mm/min and 4.29 KPa, respectively.
