The Quality Test of Utilization of Palm Oil Solid Waste As a Raw Material For Refuse Derived Fuel (RDF) For Alternative Fuels.

The use of palm oil solid waste as a raw material for refuse derived fuel (RDF) is a promising alternative to overcome environmental and energy problems. This study aims to test the quality of RDF produced from palm solid waste by paying attention to the composition of the mixture and treatment method through quantitative experimental methods, which are divided into two stages: processing and quality testing. The results showed that the average calorific value of RDF reached 4,216.75 cal/g, moisture content 10.76%, ash content 4.37%, volatile matter 58.11%, and fixed carbon 26.75%, all of which showed great potential as an alternative energy source. Although the RDF calorific value of palm solid waste is higher than the industry standard, the moisture content and ash content are still below international standards, and the calorific value is slightly below the SNI class 1 standard but higher than that of class 2 and 3. These findings indicate that RDF from palm oil solid waste has the potential to be a good quality alternative fuel.

Catalytic Graphitization by Nickel Nitrate and Characterization on Palm Oil Solid Waste Graphite

Abstract Catalytic graphitization of biomass has been extensively studied. The conventional graphitization method uses high temperatures and non-renewable carbon sources. Temperatures below 1000°C was used in biomass graphitization. The aim of this study is to how these variables affect the structural and morphological properties of the graphite materials produced. In graphite production process, catalyst impregnation is followed by heat treatment. The graphitization process starting with amorphous carbon nanospheres, is investigated by Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD) studies. XRD was used to examine the graphitization behavior of palm oil solid waste. Based on the result, the position of the 2 theta peak intensity on the XRD graph of the Ni graphitized sample is extremely near to that on the XRD graph of the raw material and carbon sample. The morphological changes that occur in the SEM images for materials graphitized with nickel nitrate are characterized by structures comparable to those that occur in carbon samples. The circular structures in the graphitized sample are anisotropic and structured without orientation bias.

Conversion of palm oil fuel ash (POFA) into foamy geopolymer for lightweight building material application by aluminum powder addition

Palm Oil Fuel Ash (POFA) is produced from the burning of palm oil solid waste biomass. POFA is abundant in Indonesia considering that Indonesia is one of the world’s largest producers of Crude Palm Oil (CPO) and has the largest palm oil plantation. The main content of POFA is SiO2 around 60%, Al2O3 around 3-10% and CaO around 5-15% so that POFA has the potential to be developed as aluminosilicate inorganic polymers. The high SiO2/Al2O3 ratio in POFA needs to be reduced for the formation of Si-O-Al chains in geopolymers. Therefore, two stages of research were carried out. Preliminary research was conducted to obtain optimum Solid/Liquid ratio. Aluminum powder was then added with certain variations to get a certain SiO2/Al2O3 ratio as well as a foaming agent so that the product can later be used as a porous building material. The preliminary results showed that the optimum Solid/Liquid ratio obtained was 0.83. The addition of aluminum powder was optimum at 2% w/w with a compressive strength of 5.4233 MPa, a density of 1339.2175 kg/m3, and a thermal conductivity of 0.6233 Watt/m°K. This geopolymer product can be categorized as a lightweight building material with criteria: a compressive strength of 0.5-10 MPa, densities between 600-1800 Kg/m3, and a thermal conductivity of 0.1-0.7 Watt/m°K which can be used as panels in buildings, casting walls, and ornaments in parks.

A microwave thermogravimetric analyzer was used to measure the characteristics of a mixture of palm oil solid waste (fiber, shell, and empty fruit bunch) and polyethylene terephthalate (PET). In the study, the range of palm oil solid waste composition ratios to PET used was 100:0, 75:25, 50:50, 25:75, and 0:100 (by weight). The study included the influence of the quality of raw material on the heating process. The mixture of palm oil solid waste (fiber, shell, and empty fruit bunch) and PET proved to impact the heating rate, mass-loss rate, and energy consumption. Based on the observation, empty fruit bunch-PET mixture had the highest heating rate (average 1.5039oC/s) than shell (average 0.6058oC/s), and fiber (0.9119oC/s) and also had the highest mass-loss rate (average 0.0253 g/s). The highest biomass (shell, empty fruit bunch, and fiber) and PET composition ratio give the highest rate of heating rate (average 1.8264oC/s) and mass-loss rate (average 0.02875 g/s). In addition, the increasing ratio of fixed carbon and material density will impact the increasing heating rate and mass-loss rate and decrease energy consumption. Therefore, fixed carbon and material gaps significantly affect the heating rate.
