Oil Palm Ash

Oil Palm Ash is one of the abundance agricultural wastes found in Malaysia. This wastes need to be disposed properly. Oil palm ash contains compounds needed to produce glass. Most of raw materials (especially silica) used to produce existing commercial glass are imported; therefore it is the best time to highlight the potential of local natural waste as the raw material in glass production. In this study, raw material characterization, glass production and glass product evaluation has been done. A few parameters have been recognized to have effect on green glass production such as mixing compositions and firing temperature. Oil palm ash has been washed and dried then sieved to get uniformity of particle size. Then, oil palm ash is mixed with other glass materials such as alumina and flux and undergone melting process at 1400°C. Through the experiments, the best glass compositions are as follows: 80% palm ash, 10% kaolin and 10% feldspar or 10% dolomite while the suitable temperature being used for sintering process to produced end product is range between 1150°C to 1200°.

This study reports on the microstructure, compressive strength, and drying shrinkage of metakaolin (MK) based geopolymers produced by partially replacing MK by oil palm ash (OPA). The OPA was used as raw material producing different molar ratios of SiO2/Al2O3and CaO/SiO2. The geopolymer samples were cured at 80°C for 1, 2, or 4 hours and kept at ambient temperature until testing. The compressive strength was measured after 2, 6, and 24 hours and 7 and 28 days. The testing results revealed that the geopolymer with 5% OPA (SiO2 : Al2O3 = 2.88 : 1) gave the highest compressive strength. Scanning electron microscopy (SEM) indicated that the 5% OPA sample had a dense-compact matrix and less unreacted raw materials which contributed to the higher compressive strength. In the X-ray diffraction (XRD) patterns, the change of the crystalline phase after heat curing for 4 hours was easily detectable compared to the samples subjected to a shorter period of heat curing.

Oil Palm growths in Indonesia are getting higher every year. Oil palm plantationproduced various waste, including oil palm empty fruit bunches (OP-EFB). 95 % Indonesia energy demand still provided by the fossil fuel and only 5 % provided by renewable energy, which provide opportunity of OP-EFB biomass pellets to be utilized as alternative resource. The research of biomass still low, especially research of OP-EFB biomass pellets. Therefore, the research objectives were to determine the production process of OP-EFB and to define the most effective binder and binder ratio for the biomass pellets. This research experiments  consist of shredding, chopping, drying, grinding, and sieving as raw material pretreatment. Also, varying the binder and binder concentration of the mixture between raw materials was the part of this thesis research. The binders used in this thesis research are PVAC paste and tapioca based paste with 4 variations of concentration. The analyses of the biomass pellets characteristic are density,compressive strength, proximate analysis (moisture, ash, volatile matter, and fixed carbon), calorific value, combustion rate, and gas chromatographic & mass spectroscopy (GCMS). The result shows that OP-EFB biomass pellets are qualified to be considered as biomass pellets. The most effective OP-EFB biomass pellets is biomass pellets with 10% tapioca binder concentration.

The process of the raw materials mixture heat treatment in the foam glass production is of great importance in the formation of the finished product thermal characteristics. Selection of optimal temperature regimes at the stages when the process of glass particles melting is activated and thermal decomposition of the gasifier occurs is of particular importance. Otherwise, a situation when the gasifier has decomposed by mass on the layers close to the material surface at that the reaction has not been initiated at the raw materials mixture center may emerge. The problem can be solved by the uniform heating throughout the raw materials mixture entire volume. The fact that excessive heating can entail additional financial costs for manufacturers’ energy resources and as a result the cost of the material can be increased and affect its competitiveness among thermal insulation materials should be taken into account. A method for calculating temperature fields allowing to simulate the thermophysical heating process in the center of the material under study on the basis of its surface temperature indicators has been presented in the paper. Such an approach may make calculation of the rational time intervals for the raw material mixture heat treatment prior to the foaming stages and partially optimization of the production process possible.

Abstract A glass set with a high content of blast-furnace slag and a reduced amount of traditional raw materials requires optimization of the raw material composition and adjustment of its specificity to the temperature regime of melting, homogenizing and clarifying the glass mass. The introduction of an increased amount of blast-furnace slag allows to reduce the cost of raw materials: soda, limestone and high-class sand, reduce energy costs, whose consumption significantly decreases and reduces CO2 emissions in line with EU requirements. The tests of thermal analysis of a glass set with different contents of Calumite are aimed at learning the mechanism of its operation by determining the changes caused by its different presence in the course of subsequent reactions between the components of the glass set. Analysis of the influence of the addition of different Calumite slag contents treated as a substitute for the raw material on the melting process of glassware sets was analyzed. The tests were carried out using differential thermal analysis (DTA) and thermogravimetry (TG) based on the model glass [mass%]: 73.0% SiO2, 1.0% Al2O3, 10.0% CaO, 2.0% MgO and 14.0% Na2O. The effect of combining Calumite with sulphate and multi-component fining agent—mixtures of As2O3, Sb2O3, NaNO3 in proportions of 1:1:1 for chemical reaction and phase transformation, was investigated.

The Middle Ages

Scientific research and a series of important archaeological discoveries in recent years have opened up new perspectives on the study of ancient glass. Glass production seems to have been organised on a hierarchical basis. The primary workshops, mainly concentrated on the Syro-Palestinian coast, prepared the raw material by fusing sand from the river Belus with natron from Egypt. The product was then sent in blocks to all secondary workshops, the organisation of which was less elaborate. Here work was limited to re-fusing material that had already been worked. The widespread commercial movement of raw glass from East to West seems to have only come to a halt in the 9th c., when the export of natron from Egypt stopped. Consequently, a different flux was used, which was incompatible with the oriental sand. The adoption of local raw materials in the place of natron meant that the management of the entire production cycle became gradually autonomous, at different speeds and in different ways, during the course of the Middle Ages.

Preheating Temperature

In the conventional soda-lime glass production, loose raw materials are normally mixed into a glass batch for melting. Dusting and segregation of the loose glass batch are always occurred during the melting process inside the glass furnace. Also, the loose glass batch has low thermal conductivity which limits the glass melting ability and pulling rate of the glass furnace. Granulation and preheating of glass raw materials have been proposed to solve the problems. In this study, the granulated soda-lime glass batch (SiO2 50% Na2CO3 22.5% CaCO3 12% NaAlSi3O8 9.5% BaCO3 2.5% ZnO 1.75% Sb2O3 1% and K2CO3 0.75% by weight) was prepared to study the melting ability in an electric furnace. The granulated batch was also preheated at 500-600°C before melting. The preheating temperature was matched to the temperature of flue gas at the bottom of the stack in the glass furnace. The purpose behind this was aiming to recover the waste heat from the furnace. The experiment exhibited the increased melting ability for the granulated-preheated glass batch

Oil palm empty fruit bunch (OPEFB) is considered the cheapest natural fiber with good properties and exists abundantly in Malaysia. It has great potential as an alternative main raw material to substitute woody plants. On the other hand, the well-known polymeric hydrogel has gathered a lot of interest due to its three-dimensional (3D) cross-linked network with high porosity. However, some issues regarding its performance like poor interfacial connectivity and mechanical strength have been raised, hence nanocellulose has been introduced. In this review, the plantation of oil palm in Malaysia is discussed to show the potential of OPEFB as a nanocellulose material in hydrogel production. Nanocellulose can be categorized into three nano-structured celluloses, which differ in the processing method. The most popular nanocellulose hydrogel processing methods are included in this review. The 3D printing method is taking the lead in current hydrogel production due to its high complexity and the need for hygiene products. Some of the latest advanced applications are discussed to show the high commercialization potential of nanocellulose hydrogel products. The authors also considered the challenges and future direction of nanocellulose hydrogel. OPEFB has met the requirements of the marketplace and product value chains as nanocellulose raw materials in hydrogel applications.
