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.

Effects of design parameters (magnetic driving force (M), cutting angle (S) and frond moisture content  (MC) on the specific cutting force (SCF) and specific cutting energy (SCE) for cutting oil palm fronds are investigated. Two types of linear magnetic actuators (500 N and 750 N) and three cutting angles (30o, 45o, and 60o) were tested on two levels of frond moisture content (<50% and >50% moisture content). Experiments conducted revealed that cutting angle and frond moisture content have a significant effect on SCF and SCE, but not the magnetic force. The minimum values of SCF and SCE were 0.3866N/cm2 and 2.0459N/cm, respectively (cutting angle of 45o, moisture content >50%), while the maximum values of SCF and SCE were 2.9432 N/cm2 and 4.1219 N/cm, respectively (cutting angle of 60o and moisture content <50%). The study also revealed that cutting drier fronds (low moisture content) increased the SCF and SCE significantly. A prototype of an oil palm magnetic cutter was developed. Functional tests carried out showed its cutting performance was 254-frond/hour, proving that magnetic force was capable to be used as cutter’s actuator.

The oil palm industry produces solid waste such as oil palm fronds (OPF) and empty fruit bunches (OPEFB), but the utilization of the OPEFB waste is still limited to composting. Even the palm fronds are only left on the farm without being processed. While both types of waste contain a lot of cellulose and can be processed into more economic value. In addition to compost, the two types of waste can be used as pulp and paper. Hence, in this study, the two wastes are processed into the paper with a variety of concentrations of solvents and mixtures. The aim is to determine the effect of solvent concentration in the process of making paper pulp and the effect of the comparison of the mixture of paper pulp with the characteristics of the paper produced. Each material is processed into pulp by the soda process using sodium hydroxide as a solvent. While the solvent concentration used is 20%, 30%, and 40% for materials from OPEFB, while the material from OPF is only mixed with 20% sodium hydroxide solution. Then the pulp, OPEFB pulp with various variations of solvent, mixed pulp with the ratio of OPF pulp and OPEFB pulp of 1: 3; 1: 1; and 3: 1 processed into paper. The resulting paper was analyzed to study folding strength, tear strength, and paper thickness. The results of the study prove that the folding endurance and tear resistance of the paper have smaller in the greater concentration of the solvent. By contrast, the thickness of the paper is greater. Besides, more the mass of OPEFB in the pulp mixture, then the folding endurance and tear resistance of the paper have less, while the thickness is decreasing.

This paper aims to understand the difference in characteristics of activated carbon produced from oil palm fronds (Elaeis guineensis Jacq) through the addition of two different activators, namely sodium carbonate (Na2CO3) and sodium chloride (NaCl). To do this, activator concentration of 10 percent each with activation temperature of 600 oC were applied in the experiment. Moreover, to determine the quality of activated carbon produced, a morphological analysis of activated carbon surfaces as well as FTIR spectra analysis on activated carbon. Identification using FTIR spectrophotometer revealed that the activated carbon in this study contained functional groups of O-H, C = O, C = C, C-C, and C-H.
